Hello :-) Get a phone holder for $10-$20 off amazon/ebay /Aliexpress :-) It will make it much easier.
But don't spend too much on accessories. I started with a identical telescope (other brand) and it's limited regarding stability, and what a 3" aperture can show.
While you'll read that more magnification is possible, the 76mm reflector isn't really made for more than 120x or so. The image will just get dark and dull.
A 6mm gold-line is a good budget eyepiece and useful for future telescopes. 1, 2. Cheaper "Plössl" eyepeices of this focal-length have a too short eye-relief.
For deep-sky, you don't need high magnification. Something around 15 to 20mm will actually show fainter structures better.

Do you have a guide such as "Turn left at Orion"? It's the missing manual on what to observe, how to obseve, what to expect.
Sorry, despite the popular opinion, I can't be on-line and everywhere all the time and need sleep too ;-) Different time zones for me. And work, of course...
In the other topic there wasn't any question regarding eyepieces?
With 6" and 1270mm focal length, the same applies to the RV-6 than the typical recommendations for the 6" dobsonians, as the focal length is very similar.
Sadly the telescope only has a 1.25" focuser, so you'll get the largest field of view with a 32mm Plössl. As you already have a 28mm the difference will be minuscule. A 40mm Plössl is available but just has a smaller apparent field of view.
For planets, a 6mm will work well. As /u/MattsAccount wrote, the gold line is one of the standard recommendation. It's cheap, a modified Plössl IIRC, but with longer eye relief and a larger apparent field of view. 6mm66° -> China / US
For deep-sky i would usually recommend a 15mm gold-line as well, but as you already have a 18mm Plössl, you might want to consider a 9mm or something like that.
Just as general idea, here's the simulation of a 1200mm telescope with different kit eyepieces;
More than 200x is possible, but atmospheric seeing will often prevent it, and 300x will already be pushing the limits. The image get's dim, dull.
A 4mm will be too much, a 5mm too close to the 6mm to really make a big difference.

(random link, do check seller ratings. Corvus optics is out of stock. Else 4.5mm Astromania via Amazon)
Do not buy a 4 or 6mm Plössl, the eye relief is horrible.
A barlow can work too, e.g. 9mm gold-line + 2x barlow, or existing 18mm + 3x barlow -> But the budget barlows will ad some chromatic aberrations, and for the price of a good one you can get a gold-line or two.
You can modify the cheap 6mm gold-line for more magnification by simply adding a spacer in-between the top part and the bottom barrel, if you like to tinker. :-)
Hello :-)
As mentioned by /u/mhc2001 AND OF COURSE /U/_AUGUSTUS (^;-) ), the AWB Onesky is a great starter telescope despite it's quirks. The Zhumell z130 and the Lightbridge Mini 130 are very similar, but the closed tube has contrast benefits, and the focuser is less wobbly as well. The OneSky is more compact though.
Sometimes you can get a used or refurbished 6, 8" dobsonian for the same price. Currently, telescope.com has a "2nd" (used/refurbished) for $225 or so.
A 6" dobsonian is larger (size/portability links, but compared to the table-top telescopes it does not require something to put it on, and it will show more (Links on what to expect in different telescope aperture sizes). Also, due to it's aperture ratio of f/8, it has contrast benefits and works better with cheap eyepieces.
New, the Skywatcher 6" has better focuser and finder. The Zhumell z8 is the best deal overall, as it already includes so many accessories it's considered the best bang for your buck; But way over your budget.
All telescopes have very basic accessories. So one or two more eyepieces are recommended, especially as most lack of a "planetary" eyepiece. Do not get a cheap short Plössl (too short eye relief) or eyepiece set (overpriced, mediocre at best despite good reviews).
For the 5" table-top, a 3.2mm or 4mm HR Planetary clone (Aliexpress $25-$35, Amazon or Agena Asto ~$45-$60) work nicely.

For the Orion XT 6-inch dobsonian, a 6mm will be nice to have and it's actually cheaper (usually; 1 2).
A collimation tool is nice to have to get the best contrast with your telescope, but you can do it without or make one. 1 2

Hi :-)
6mm 66° afov clones
Great budget eyepiece for a 8" dobsonian. More magnification is possible, but only if the atmospheric seeing allows. ~3.2mm-4mm HR Planetary clone or similar can be fun IF seeing alows and doesn't cost more than a decent budget barlow;
Now, who whould that be? :-)
I also saw this one at Amazon, and of course the one on Aliexpress.
Also see this simple graphic on eyepieces for a 8" dobsonian.
The Orion have very basic accessories;
Consider getting a 6mm and a 15mm, possibly a 25-30mm wide-angle (>70° afov) eyepiece.
http://blog.pixelgiraffe.com/wp-content/uploads/2016/11/dobson8eyepieces1200.png
A 25-30mm wide-angle eyepiece, at F/5, ideally a better one such as the Explore-Scientific 82° for a large field of view.
:-)
The Zhumell z8 already includes a 2" wide-angle eyepiece worth $70, so even though it's $389, it's a better deal than the $355 Skywatcher. Not to mention the other accessories included. :-) The 6mm costs $18 when ordering at Aliexpress, $30 at Amazon.
Eyepieces are very different. A cheap 6mm Plössl has short eye-relief, a 32mm Plössl is better but the field of view smaller than a 2" wide-angle eyepiece. Not all 2" eyepieces are good though.
Orion has "2nd" clearance sales, but telescopes come and go.
Sometimes they have the xt8 for $290, sometimes the xt6 for $190-230, sometimes the xt4.5 for $160-180 or so.
If you are going with the 130mm telescope, you don't need a lot of eyepieces. Even with the kit overview eyepiece, these short telescopes offer a relatively large field of view (simulation). The only thing really missing is a 3-4mm eyepiece
$20 at Aliexpress
around $45 at Telescopesplus
A barlow is possible too, but the cheap ones ad chromatic aberration. And don't use too much magnification, the image will get dim, often more than 200x won't be possible due to atmospheric seeing anyway. 1 2
With the z8, all you really need to get started is a good guide and the 6mm. Simulation. When ordering the 6mm at Aliexpress, that's a total of around ~$410 with a lot of accessories compared to what the other manufacturers dobsonians include. A 8" can last a life-time, if you have realistic expectations regarding visual astronomy. If you where to buy the Skywatcher 8" with a 2" wide-angle eyepiece ($70 and up) and other accessories it will easily cost $500+. Still, it has a better finder than the Orionxt8 and even with the stock accessories it'll show a lot ;-)
Still, the 130mm telescopes (but especially the AWB Onesky) are very portable telescopes at a fair price, outperforming almost everything in this price-range. The only catch is their low size, but a crate or "Bekväm" cost very little and still provide a more sturdy experience than the cheap eq2-type mounts in this price-range.

Hello :-)
What to expect in different telescope apertures
The Zhumell already includes many accessories, and the only thing really missing to start with, is a decent 6mm 1, 2 (also see this)
The many accessories of the 6SE are simple Plössl (52° afov). Under 10mm they have horrible eye-relief. Filters can be useful, but you rarely need more than one.
That said, the 6SE is not bad at all, but it really depends what you want. If you want to observe as much deep-sky objects as possible, and with more maximum field of view, the z8 is a much better offer. For $450 new, you can get the z8 and one or two eyepieces, and a good guide. With a good guide, manually finding things is really no big deal.
Either way, clear skies :-)
Hello :-)
A 8" is a very nice telescope, as it already shows quite a bit regarding deep-sky... And planets as well of course ;-)
What to expect visually in different telescope aperture sizes
A dobsonian is sturdy and cheap thanks to the simple "rocker-box". It's quick to set up and intuitive to use, but as it's not an equatorial mount, tracking the planets at high magnification requires a bit of practice; Nothing that's overly difficult though.
Do consider the size though. Especially if you live in a light-pollute area, you are stuck observing the planets (three with noticable surface details, and they aren't always up) and some brighter DSO.
As mentioned, in the US-> Zhumell z8; In Europe-> GSO Deluxe 200. They already include a 2" wide-angle eyepiece. But even those can use a "planetary" eyepiece. Do not buy a cheap short Plössl (short eye-relief) or eyepiece kits (overpriced, despite positive reviews).

They just sell them, Corvus had them even cheaper. On eBay, you can get them for $30-$36 1 2 - And of course at eBay 1 and Aliexpress 2 (random links, compare seller reviews).
The "original" are the Orion Expanse (blue, else identical). Years back a german site compared different ones; Some from brands (Skywatcher), in-house brands, and some no-name ones. Thy where all usable, some of the cheaper ones had better black coatings than the brand eyepieces... But it varies. Quality control is one issue when importing no-name stuff; But so far they seem alright. I have a couple of no-name eyepieces, among one gold-line, and it works just fine.
Hello :-)
Where are you from? In the US, the Zhumell z8 is a better deal due to it's great accessories.
In Europe, there's also the GSO Deluxe dobsonian sets, but they are more expensive than the Skywatcher 8" or basic GSO dobsonians.
Also get "Turn left at Orion";
Set eyepieces are very basic, but don't buy an eyepiece kit. A 6mm will probably be the most useful for planets (more magnification is possible, but only if atmospheric seeing allows)
http://blog.pixelgiraffe.com/wp-content/uploads/2016/11/dobson8eyepieces1200.png
A decent beginner 6mm eyepiece with good eye-relief would be the "gold-line" series. Do not buy a short Plössl or set. CH US UK
Also get "Turn left at Orion" - The missing manual on how to observe, what to expect, and what's worthwhile observing.
While a 8" is pretty much universal, do not underestimate the size of it (links). Also, be aware of what to expect realistically.
Clear skies! :-)
