Has been years since i used it but was incredibly useful
I use a mobile app called Stellarium. You should note, it costs $2.49, but I thought the price was worth it. You basically choose a point on a map, or you can use GPS to have it locate where you are for you. Then once you have a location selected it will tell you everything that's in the sky, what direction it's in, and what time it'll be there. It will even tell you if the ISS is going to pass by. Personally I find it very handy.
If you have a smart phone stellarium is awesome

I live in the SF Bay and there are some nice planitriums here, are you sure there are none by you?
I also read spacenews.com daily I find their articles interesting.
You're still lucky though. Madalas, kahit gaano kaganda plans mo, from time, location and gears, pag tinamaan ka ng malas like masamang panahon or sadyang maulap, wala na.
Anyway here's the link to Stellarium Mobile hope this helps.
I use Stellarium, pretty good features for a free experience. You can use your hands to manipulate the UI or simply point your phone up at the sky and use it as a guide. You can see realtime satellite flybys, but I use a different app (ISS Detector) to notify me of those and Iridium flares, which are sadly gone forever now.

I'd say Mars yep.
If you're interested, You might want to get yourself an app like Stellarium. Just point your phone with the app at the star, and it'll tell you. You can also download it for PC/Mac
The easiest one I've found is Stellarium (https://play.google.com/store/apps/details?id=com.noctuasoftware.stellarium_plus&hl=en_US&gl=US&pli=1) - they do have a free version but I haven't used it so I can't speak to differences between that and the paid.
Just point your phone in the direction you're looking, and it will overlay stars, constellations, satellites, etc.
Hi!
Note that there are 2 distinct stellarium applications for mobile.
First one is Stellarium which was last updated on March 21 2019. This is the free version which I am guessing you are using and doesn't have the updated locations in it.
Second one is Stellarium Plus which was last updated on July 12 2020. This is a 10 USD paid app, which should have NEOWISE in it's database.
My humble opinion is that it is not so user friendly that you have to manually upgrade the desktop application's database and also it is not noted that the free mobile app does not get these database updates.
Phone, text, and email make up probably more than 95% of what I do on my phone, so my old S4 is more than adequate. I occasionally look something up on the net, and I sometimes use Stellarium to see what's in the sky at night, but that's about it.
(Here's the desktop version of Stellarium in case anyone is interested: http://www.stellarium.org/. Free and open-source, although the Android version is US$2.49.)
Una vez que pones tu ubicación te manda a la pagina principal y viste que te sale la lista de satélites? Haces click en alguno, los mas brillantes para verlo desde la ciudad son la ISS, el Hubble, los Iridium o si no fijate el que dice "Predicciones diarias para los satélites más brillantes". Algo mayor a magnitud 2.0 olvidate de ver en la ciudad (La magnitud es el brillo que tendrá, mientras menos magnitud mas brillo, osea que la ISS que a veces tiene -2 la ves bien).
Me fui de tema, volviendo a tu pregunta, para ver por donde y cuando va a pasar, hace click en el nombre de algún satélite, te abre un cuadro que te muestra la fecha, magnitud y la hora de inicio y para ver por donde va a pasar hace click en la fecha y te abre una carta celeste. Es fácil leerla, está hecha para que la pongas arriba de tu cabeza y apuntando los respectivos puntos cardinales tratá de localizar alguna constelación conocida y espera a que sea la hora nomas.
O si no queres complicarte mucho bajate este programa a tu pc o la app (busca el apk de la última versión si sos medio ratón), haces lo mismo de configurar tu ubicación y te simula tu cielo y si te fijas tiene una opción que te muestra el paso de los satélites
Stellarium - totally worth the $2.50. It's an amazing star-gazing app. I bought it when I wanted to do astro-photography. It tells you what's above you for any given time of day or location, and has a ton of lovely features I that if I tried to list would end up selling the app short- including red-light mode so its easy on the eyes to view the app at night.
Other must haves (for me) are:
- IMDB
- ES File Explorer
- Push Bullet
- Evernote
- Relay for Reddit
Stellarium, hands down. Google Sky Map hasn't been updated in ages, and it doesn't do a fraction of the things that you can do with Stellarium. I use this app both on my phone and on my laptop when out stargazing with the scope.
Stellarium is great also, you can superpose your phone onto night sky and identify stars and constellations.
You can also change your location, date amd see how the sky was/will be.
Also available on pc.
This image was created with 24 individual exposures of 30 seconds each. I have a remote shutter release button that I plug into my camera, and it can simulate me holding the camera button down. I set my camera to take 30 second exposures at ISO 400, removed the lens, and then bolted it to the back of an 8" Schmidt-Cassegrain telescope.
When you take long exposures of space through a telescope like this, the rotation of Earth about its axis will create star trails and blurred images. That's where the mount comes in! I have a Celestron CG-5 equatorial mount that I align to our planet's axis of rotation. Once it's set up, tiny motors in it make it rotate with the sky, eliminating the possibility of trailing stars. The alignment process takes me about a half hour because once once it's all fully aligned, you have to make slight adjustments and start over a few times. If people are interested in seeing how all of this is done, I might put up a video sometime in the near future showing how it's all done.
So here's a simple step by step for how to make your own image!
My materials (this is all mid-upper range stuff for an amateur I'd say):
Digital single lens reflex (DSLR) camera. I use a Nikon D5300. - $597
T-adapter. This goes onto the back of the telescope, one size shild fit all Schmidt-Cassegrain telescopes. - $24
T-ring for Nikon. This is what mates your camera to the t-adapter. Specific to camera manufacturer. - $10
Power supply. This powers the mount so it can track the rotation of Earth. - $57
Total price: $2288. You could definitely get by with a smaller telescope and a cheaper mount. You also don't need a $600 digital camera. Save your money and this is definitely an achievable purchase!
Imaging process:
Throw everything into the back of your car.
Go to this page to find the darkest area you can find. Light pollution from cities and even the moon will make a HUGE difference when you're taking long exposures of space.
Go to this page to see if the sky will be clear. It's surprisingly accurate. Just plug in your own address or coordinates. The coordinates that I linked are from where I took my pictures last weekend.
Drive to your dark sky site!
Set up tripod, attach mount facing as close to north as you can. Secure everything tightly, and then bolt down the optical tube assembly on top.
Balance the OTA on your mount by loosening the mount locks and moving the scope to the side. Adjust the mount's counterweight and the position of the scope in the mount slide. If you want, you can attach the camera now to account for its weight.
Attach mount to power supply. If it's going to be cold, I suggest leaving the power supply in your car and running the cord out the door jam. Batteries don't like cold temperatures.
Turn on mount, enter your time and location, begin alignment process! I use an app on my phone called Stellarium [iOS] [Android] to help me with the alignment. The mount will spit out a star name, and it will slew to where it thinks it should be. Use the direction buttons to fine tune it. If you can't see it and you're not used to the finder scope, try de-focusing the telescope. A big ring of light will show you where any nearby bright sources of light are.
After you have done the 2-star align and have added 2-3 calibration stars, go into the alignment settings and do a polar align. Follow the instructions, and it will tell you to adjust the mount itself (NOT the direction buttons). This fixes for human error when initially setting up the mount.
Now that you've aligned your telescope, turn off the power and do it again! Now that you've aligned the telescope's axis of rotation with that of planet Earth, performing another 2-star align (with calibration stars!) will make things better. If I know I'll be doing longer exposures, I cycle power and re-align my 'scope twice. It used to take me 45 minutes or so, but I've gotten it down to about 20 minutes for a good telescope alignment.
Next, tell the mount to point at something interesting! In my case with this image, I was killing time taking pictures of the Andromeda Galaxy and the northern lights until the constellation of Orion rose.
Once you have your subject in the scope, you probably won't see anything too interesting. Most bright images of nebulae will only look like a faint smudge. When shooting a dark nebula like the Horsehead Nebula, you won't see anything at all.
Attach your T-adapter, your T-ring, and then your camera to the back of your telescope. I use a corded remote to do my exposures because I can set my camera to "bulb" (exposures for as long as you're holding the shutter release). The remote has a lock that holds the shutter button down.
If you used an eyepiece to align your scope, now you'll need to readjust your focus. Go to live view mode on your camera, and set the ISO to as high as it gets. Adjust the telescope's focus until stars are super sharp. If you'd like, you can invest in a cheap filter to throw on the objective end of the 'scope called a Bhatinov mask that will create light artifacts that will show you how focused you are.
Start exposing! Have your camera set to manual mode (important, you don't want your flash going off!). Since the camera isn't connected to a lens, it has no control over focus or aperture. You've got image sensor sensitivity and exposure time. For Orion I shoot 30 second exposures. I lock down the shutter release with my corded remote so that it can take 30 second exposures immediately one after another. Take anywhere from 20-100 images. My image is 24 30 second exposures, for a total of 12 minutes of exposure time. Nothing special.
Throw all of your images into a software like Deep Sky Stacker (Free) and watch it do its magic. It will use image processing algorithms to combine all of your images into one higher quality photo! You can also add dark frames (literally exposures with the lens cap on) to cancel out image sensor grain (noise).
Really, anyone can do this. I'm just a normal dude with a fun hobby.
Jos ei ole star adventureria, ni tällainen vanha kikka päästää melkein samoihin tuloksiin ilman seuraavaa jalustaa:
Valotusaika 20 - 30 sekuntia (riippuu kuinka laajakulmanen objektiivi. Mitä laajakulmasempi, sitä pidempää suljinaikaa voi käyttää ilman että tähdet näyttää viivoilta.
Objektiivi laajakulmapäähän.ISO-arvo johonkin 3200 - 6400. Tää toimii ihan jees vielä Nikon d7000 kameralla, joka itsellä käytössä.F 1.8, tai 2.8, tai mikä ny onkaan suurin sun objektiivissa.Tarkennus äärettömään.
Tarkoituksena on siis ylivalottaa kuva. Kun kuva on otettu, taivaan pitäisi kuvassa näyttää lähes valkoiselta. Kato histogrammista kuitenkin, että ei klippaa mistään täysin valkoiseksi, vaan siellä on hiukan käppiä.
Kuvaat tietenkin RAW formaatissa. Sitten himassa avaat kuvan jossain kuvankäsittelyohjelmassa, esim. photoshopin RAW-filtterissä, tai affinity photossa, tai missä lie ja palautat sillä exposure arvoa taaksepäin niin kauan, että taivas näyttää normaalilta.Silloin tähtien pitäisi näkyä kuvassa ja voit kontrastia ja kaikkia näitä kliksuttelemalla vielä saada sen näkymään selkeemmin.
Kuvassa ei pitäisi näkyä kohinaa kauheen paljon johtuen ylivalottamisesta, joka hävittää suuren osan kohinasta.
Valosaaste pilaa kuvat. Katso hyvä paikka tällä: https://www.lightpollutionmap.info/

What are the apps like? I have a few Andrioid apps which I paid for because I like them. (Stellarium, My Boy! Gameboy emulator, and Mupen64PlusAE to name a few.)
I understand that apps probably aren't completely portable but I like the functionality of my Android device. This is the main reason I haven't rooted my device, I really like the 'it just works' part of my phone, and I am really hesitant to mess with something I rely on every day.
(Which is funny considering how I feel about Linux on my laptop. It's a standard, and I wouldn't be caught dead without it.)
All of these applications (aside from on PC's) allow for augmented star gazing. You simply point your phone up (or down, if you'd like) and the sky will be displayed on your screen. Stars are labeled, constellations are shown, deep space subjects are present, and our Milky Way is nicely displayed. The app also allows for you to go forward or back in time to plan your night of gazing/photographing. Stellarium is a very well known application for not only its ability to augment the stars, but for PC, the software can be hooked up to a telescope to even track the stars for great astrophotography.

Hi there! Welcome to this awesome hobby.
First of all, good choices! Either scope will suit you very well. 8" of aperture is plenty to show you the planets and many DSO's.
If I had to choose between the Orion XT8 or the Zhumell Z8, I would go with the Zhumell - the reason being that the Zhumell comes with better accessories than the Orion one does (better 2-speed focuser, two good eyepieces, a 1.25" moon filter, right-angle finder, and a few other things). Up to you, but I think the Z8 is the better of the two.
A 2" barlow would be a good addition to your collection, as it would effectively give you eyepiece focal lengths of 30mm, 15mm, 9mm, and 4.5mm, which would all fall within the limits of your telescope (see a lengthy comment I made the other day about eyepieces and barlows). You won't necessarily need to buy a moon filter if you choose the Z8, as it comes with a 1.25" moon filter (though, this filter cannot be used with the included 2" eyepiece).
What kind of skies to you plan to observe from? Do you live in the heart of a city? Do you live in a rural area? Dark skies are very important when it comes to deep-sky observing, as light pollution will effectively wash out most deep-sky objects.
If you plan to observe from dark skies, away from city lights, you may wish to consider a Telrad. The Telrad allows you to aim the scope with zero magnification, using only the stars you can see with the naked eye (hence why it's only really useful in dark skies).
If you plan to do deep-sky observing, you're going to want some sort of star chart or planetarium software/app to help you find objects, and also I suggest you do some reading to learn about star-hopping. If you would prefer to use a laptop, Stellarium (free) will likely be your best bet for planetarium software. If a smartphone or tablet is a better option for you, a few good apps that I know of are Stellarium Mobile ($2.49), SkEye (free), and Night Sky Tools (free) (all on Android, no idea what's out there for iOS). If you would prefer to use a printed star atlas, the best one I can probably recommend to you is the Pocket Sky Atlas ($19.95). Alternatively, you can download and print the "A" and "B" sections (skip section "C") of the TriAtlas (free), but you may find this atlas to be too cluttered and confusing.
If you live in or near a city, I highly recommend contacting a local astronomy club (good chance your local university might have one). They can give you some help that we can't, such as showing you telescopes in real-life (so, if you wanted to see what an 8" dob looks like before you pull the trigger, there's a good chance one of the members would have one as they're quite common). Also, they'll be the ones that will hold star parties, which can also give you a chance to get some advice from experienced observers while you're observing. Plus, it's more fun to observe with others. Oh, and don't be afraid to contact them - I can guarantee that they will be glad to help you out. :)
Anyway, hopefully that's useful, and feel very free to ask any other questions about telescopes that you might have! :)
Clear skies!
Hi there! Welcome to this great hobby.
Looks like you've done your research - all four of the scopes that you've mentioned are very capable scopes. Of course, the dobsonians will show you quite a bit more due to the extra 4-6" of aperture. It will ultimately be up to you whether you want to have a computerized scope for the expense of aperture, or learn the sky and learn how to star-hop (not as daunting as it sounds). However, I would suggest you go for the dobs - you'll probably thank yourself later for getting the extra aperture.
If you choose to go for a dob, I would suggest the Zhumell scopes over the Orion SkyQuest ones. The Zhumell scopes are made by GSO and tend to ship with better accessories (smooth 2-speed focuser, two pretty decent eyepieces, laser collimator, right-angle correct-image finder), as opposed to the Synta-built Orion SkyQuest scopes.
As for portability, a 10" dob shouldn't be too bad unless you have a really small car. Find a place for the tube (back seat), find a place for the base (passenger seat or trunk), and then stash eyepieces/finders/filters/etc somewhere (floor/trunk). Same goes for the 12", but just be sure your car is wide enough for the tube. Just be prepared that the tube for either will probably be a little bulky and awkward to carry around (most of the weight is in the mirror, so it's pretty lopsided).
For accessories, you'll first want to either get a star atlas (Pocket Sky Atlas and Sky Atlas 2000.0 are both good, kinda spendy though) or download Stellarium onto you laptop/smartphone (the laptop version is much more advanced, and free) so that you can navigate your way around the night sky. You may also consider purchasing a Telrad, which helps you find objects in cases where the finder scope isn't helpful. Other accessories to consider are an extra eyepiece or two and perhaps a narrowband/UHC filter. However, none of these are exactly crucial, so you can always think about these later.
For objects to look for, other than Moon and the planets, the first step is always to check out what Messier objects are up on any given night - all of these would be visible in either the 10" or the 12". Another good catalog to keep in mind is the Caldwell Catalog, which essentially picks up where Messier left off.
Anyway, hopefully that's helpful, and feel free to ask any other questions you might have!
Clear skies!
EDIT: Totally forgot about Michael Vlasov's Deep Sky Hunter Atlas. It's free to download and print. If that's too detailed, he also has a less detailed TheSky version.
whenever theres a particular star in the night sky that i cant identify, I usually refer to Stellarium app.
https://play.google.com/store/apps/details?id=com.noctuasoftware.stellarium&hl=en_US
Stellarium is a free download for both PCs and smartphones. This will show you where the stars are and you can accelerate time and move location.
The Photographers Ephemeris (TPE) - PC and Smartphone - http://app.photoephemeris.com/ - Shows sun/moon rise/set - blue and golden hours
Photopills - similar to TPE but on steroids - covers a WIDE range of applications - http://www.photopills.com/
Google Earth (free download for PCs) for photo locations and to see what others have shot
For LED lights - post at https://www.reddit.com/r/flashlight/ for help on everything for lights / batteries / chargers. Lots of friendly help. You will probably want two types - a thrower for long range spot, and a flood for a wide angle flooding light for a large area.
Stellarium is so much better.
I don't know what he's talking about, but I have a version of Stellarium for Android downloaded.
Caveat: I'm not sure that any of the money from the download actually goes to support work on the official project, but they don't appear to be in violation of the GPL, as far as I can tell, and the dev who created the app seems to be a contributor to the official project.
Another really neat astronomy related project you should check out is Celestia, which is a real-time 3D model of much of the known universe (or at least this galaxy). It's exactly as cool as it sounds.
I actually downloaded this app on my phone: https://play.google.com/store/apps/details?id=com.noctuasoftware.stellarium&hl=en
Just open the app, give it a couple of seconds to load and hold your phone up to the sky and scan the sky, Then you can look at that general direction and spot the comet.
Here is a screenshot of the app when I was holding my phone pointing at the comet: stellarium app
Hope it helps. :)
Get the Stellarium app and point your phone at the star, it'll tell you what it is.

May I recommend Stellarium on PC and on your iPhone or from the Google Play store
Point the phone version at the sky and it'll show you what is there.
I most enjoy Stellarium and The Guardian.
Yes!
Depending on airline, I usually wait until the day of my flight to upgrade my seat to get a window seat, typically where there is no one sitting next to me. This helps me have a place to manage my gear (amateur photog myself).
I'll also consider the prevailing winds and current weather for the locations I'm flying into and out of. Prevailing winds often dictate the direction an airport is facing, and the direction the air traffic navigates to and from the airprot.
Good wikipedia article on this very phenomenon.
I also use an app called Stellarium Mobile Sky Map which helps me figure out what the sky is going to look like at certain times. This app helped me get this pic of the moon peeking over the wing of my return flight from Punta Cana.
