I get the impression this is not a 'serious' question of what you need but more of a review of both products. I have to say, for such a small telescope, that Seestar S50 is a very attractive little thing. And for that price, I'm really considering getting one.

I briefly debated a telescope and go-to mount to supplement my already existing high end DSLR.

But having tried doing telescope astrophotography briefly before and being discouraged by the hassle of heavy gear and complex setup I decided to go for both convenience and price and bought the S50.

It's compact, it's all in-one, Inclues tripod. It have solar filters as part of the kit. It have an app that works great with go-to functions and so on.

The convenience factor makes it a pleasant breeze to use(astrophotography can be a very inconvenient and fiddly hobby) and the price point is hard to beat. A very pleasant entry point to astrophotography, the dwarf 3 and S20 being the other options and I would advice against spending more before you have 200 hours of observations logged(which if you actually like the hobby will not take particularly much time)

I have one and also a small dobsonian optical telescope and a larger, heavier astrophotography setup. The Seestar gets the most use out of all of them, mainly because of convenience.

It’s neat being able to set it up in the back yard and let it go for a few hours, unlike my other rig which takes ages to set up and needs a lot of babysitting. It also packs away into a tidy little case that doesn’t take much room in the car.

On the other hand you’re limited by the small aperture lens and the quality of the camera, compared to a larger rig.

There are rumours of a follow-up model to the S50 but no idea when that will be launched.
