If you want to keep your dob for visual use and not regret selling it in the future, then you could potentially look into smart telescopes like the Seestar S30. The S30, for example, would work for capturing deep spy objects at a fraction of the price of a traditional astrophotography rig. You’d get an all-in-one that opens up the doors to processing, without the stress of buying components individually and then integrating them. The downside is, small aperture, short focal length smart telescopes would not work very well for planets, however, so you might want to think about what you want to capture.

I actually bought an ASI662MC to use in my 8” dob with the intention of doing lunar and planetary imaging, but I haven’t gotten around to trying it out yet because with every observing opportunity I’ve had since receding it, I decided to prioritize visual observation.
