RASA 8 vs Refractor

Hi everyone, my first post after lurking the forums for a while.

I'm currently trying to decide on my new imaging scope and haven't been able to find much helpful info so i'm putting it out there to you good folk. For context I've been using an 8" F5 Newtonian and a ZWO 294.

I'm after something with a wider field of view to image nebulas and some of the larger star clusters and i'm trying to pick between three scopes:

1. RASA 8
2. Skywatcher Esprit 80
3. WO Redcat 51

Out of these the Redcat has the widest FOV but i'm a bit concerned about the 51mm aperture and whether it can pull in enough light within reasonable time frames and also under-sampling on the 294 camera. The RASA is obviously going to be the quickest but it's a dedicated astrograph whereas I can use the other two for visual as well. The 80mm is a tried a true option but I like the extra aperture of the RASA.

I suppose for the money I can buy the Redcat and a camera like the ZWO 183MC Pro with smaller pixels for the same as a RASA. Then again the 80mm is a proven concept and should work with the 294.

Any thoughts?
