I have been looking around for telescopes for a while. Specifically, a telescope that can take nice bright photos of deep-sky objects. I have settled on the 8-inch StarSense Dobsonian from Celestron, as it is only 800 dollars and I'm on a tight budget. (<$800) I'm wondering if there really is THAT big of a difference between the 8 and 10-inch versions when it comes to viewing and if so, should I push my budget to get the telescope?
10-inch Vs 8-Inch Dobsonian?
10-Inch Or 8-Inch? Reasons?

Hello
you know, you have to look at the full ability to capture the light of you wish some beautiful bright pictures of galaxies. And you generally would need a long exposure for catching more details as possible. I’m recommending you the 10” dobsonian just for these reasons here

As you are aware I'm sure, Dobsonians are mostly intended for visual observation, and not for Astrophotography. But if you're on a budget, it might be a good way to break in. Most AP rigs of any quality will cost more than that. I would recommend looking at Ed Ting's videos on YouTube regarding the subject of 8" vs 10" Dobsonians. Near the end of this video, he address AP with Dobsonians: https://www.youtube.com/watch?v=E2Fq7ecjBvQ&pp=ygUSZWQgdGluZyBkb2Jzb25pYW5z

A short answer from me: no, you shouldn’t.
I don’t own a Dob, but I’ve seen an empirical rule for visual observations - in order to see a significant difference between scopes, one should have aperture area x2 times bigger than another.
This is a case for 8” vs 12”, but not for 8” vs 10”.
I would also consider portability, and ability to put the telescope on the equatorial mount for imaging (default dob mount won’t provide you such ability). You should get a solid equatorial mount to use even 8” telescope for deep sky objects.
8” gives you a good trade-off here if you want both visual and imaging, but additional investments will definitely be needed.
