Hi everyone!
This is my first time attempting to photograph the moon, and astrophotography in general. Here's what I know about my setup:
Like I said, I'm BRAND new to this, but would LOVE to learn as I'm huge into photography.
Celestron 1.25" Universal Barlow... https://www.amazon.com/dp/B00009X3UV?ref=ppx_pop_mob_ap_share
Celestron 93419 T-Ring for 35 mm... https://www.amazon.com/dp/B000237C9M?ref=ppx_pop_mob_ap_share
This is what I have. There are some cheaper ones, but I've read that the camera connection can be a port quality and not lock correctly, so I went with a name brand.
I'm also using the 2" focusing spacer that came with my AD8 as well as the 2" to 1.25" adapter. All stacked together I'm able to get a clean focus on distant tree tops at least. Waiting for clear skies....
Most Barlows from respected companies will do (except many ones that come with telescopes). For example, this one: Celestron 2x T-threaded Barlow Lens. If you want a really good Barlow, TeleVue make excellent ones, but now you're looking at $130 (!)
Some general tips:

And finally, experiment!
If you have any questions, I'm certainly not the most knowledgable but there are forums like CloudyNights out there to help.
I use one of these

And
I'm looking at getting a barlow lens to do some planetary imaging. I currently have a D3300, which I hook up to the scope with a 1.25" T-adapter and a T-ring. If I want to include a barlow in this setup, do I have to get an item that is a T-adapter and barlow, such as the Celestron barlow here, or can I get any barlow and insert it between the telescope and the T-adapter?
Also, is there a big quality difference between cheap barlows? I'm looking to spend <$50. I've heard that the Celestron one I linked is alright, as well as some GSO and Astro-tech barlows, but I'm wondering how much better they are compared to a cheap alternative like this.
One more problem- I have two telescopes, one is an old Meade alt-az goto that works fine with the current D3300 setup, and the other is an old 8" Bushnell dob. With the T-adapter and T-ring on the dob, the sensor on the camera is too far back to focus, even with the focus scrolled all the way in. How would I go about fixing this? Will a barlow make this problem worse, or fix it?
Thanks to anyone who takes the time to read through all this!
