This for power, but I'm sure you can find something cheaper

Basically, yes, but you'll also need a few relatively cheap things to make sure you have power and a way to mount the camera to the scope. And you can definitely go much cheaper (especially on the camera). I just had the camera prior to getting into astrophotography because I do photography as well.

To answer your question, the only other thing I purchased separately that was involved in my setup for this shot was the battery pack that powers the mount, a T-Ring, and a T-Adapter that allows me to mount my camera to the scope.

Again. You can go much cheaper on the camera and can actually just use a webcam to shoot the video that you'll stack into a still. Registax is free. Autostakkert is free. And there are free photoshop alternatives. You'll also want to use this program called BackyardEOS to shoot the videos at 5x zoom (My computer was acting up for this shot, so I didn't use it this time around) but it's well worth the $30 I think I paid for it. You can get even clearer shots like this one I got a while back. The program allows you to digitally zoom in at 5x using and use only a part of the camera's sensor. Please let me know if you need any other information. I'd be glad to help. Hope this helps some!

A car adapter? Mine came with one. As for the power supply id recommend this


Here is what i bought to track with it.
PC interface Cable
Serial Adapter
And finally this, but this is optional to you. Youll probably eventually want to image from your backyard, and if you do youll want this. AC Adapter

Another thing, Unluckily for me and for you, the mount does not come with a polar scope. Do some research to what kind you want, but I got this one

Other than that, Good luck! If you ever want some real time advice come check out the chat room under the useful links tab on the side of the subreddit! Chances are I'll be there, or one of the AP gurus.

I've had it for less than a month, but so far I'm really liking it for the most part. Here are some pros and cons I thought of about this scope to help you out:

Pros:

• It's great for visual observing! With it I've seen the Great Red Spot on Jupiter, moon shadows on Jupiter, the Cassini Division in Saturn, detail in Saturn's atmosphere, detail on Mars's surface, and so much detail on the moon that it almost looks like I could touch it. Deep sky objects also look great through the scope. (I live in a heavily light polluted area and I can still see some amazing things, such as certain nebulas and star clusters.)
  
  
• It's great for planetary photography. (Don't really need to explain this one, as there's an example image in this thread.)
  
  
• If you get it aligned well, the goto function works great! I've had lots of fun using it because it's a great way to discover new objects you haven't heard of before.
  
  
• Because it's a Schmidt-Cassagrian it has a lot less coma than other types of telescopes, which is helpful for both visual observing and photography. (Though you can buy a coma corrector if you get a different type of telescope.)
  
  Cons:
  
  
• Haven't tested this myself yet as I haven't needed to, but the majority of reviews for the 8SE says it sucks down the battery power in less than 30 minutes when it's on. To fix this issue, I bought a power cord, but if you want to take it out somewhere, you'll probably need to buy a power tank. (Or something like it.)
  
  
• This is not an issue where I live so I can't say any of this with experience, but since it's a Scmidth-Cassigrian telescope and has closed optics, dew can form on the corrector plate depending on the weather. (Here's a page about it with more information.) Uf you don't want to buy anything extra to fix this issue I've heard that leaving the 8SE out for about an hour before you use it will get rid of most of the dew.
  
  
• I've had a decent amount of issues with the tracking being finicky, but it very well could be fixable. (Objects tend to go out of frame over time, even when aligned. This happens most often when I tell it to go somewhere, or when I recently moved it with the arrow buttons. I do find that if I leave the telescope alone for a few minutes to let it "catch up" to its new position in the sky it can keep the object pretty solidly in the frame though.)
  
  
• Because of its mount type (Alt-Az) and its somewhat finicky tracking, this telescope is not good for DSO photography. Keep in mind it is definitely possible to get great images of DSOs with it, but it's a lot harder and if photographing them is your main goal then I wouldn't recommend the 8SE. (Here's a thread I found, in which some of the posts go into more detail about the issues I was talking about.) I bought the 8SE mainly for planetary photography, so this isn't an issue for me.
  
  
• With a star diagonal in, the telescope can't point above 70-80 degrees or so, which can be a pain depending on what you're looking at. You can fix this by moving the tube up on the fork arm more. I have heard that makes the tracking less stable because it's slightly off balanced, so I don't keep it that way, but it is an option.
  
  
  
  Hope this helped! And my apologies if you knew a lot of this already.
