Rasa 6 with a 1.25" size camera with something like an IMX178 sensor, or the ASI585MC (uncooled) could be a really potent grab and go setup for quick trips to dark skies... Sure, you won't throw a IMX571 camera on it, but it won't be used for that I don't think...
At the price of $3150 though, grab a C6 and a Hyperstar...
Horses for courses I guess. Its the same but opposite feeling that I get when you see people buy exquisite telescopes that have a corrected image circle capable of using medium format cameras and they then slap a micro 4/3" or smaller sensor in them. Same thing.
If you match your scope to your intended camera such that you can reap the benefits of both equally, you're in for a good time. Not every telescope needs to be capable of utilizing APS-C or larger cameras, and not every camera needs be suitable for every telescope that comes out either...
RASA6 with IMX585 would be great.
FSQ106N and IMX585 would be silly.
RASA6 with IMX455 would be silly.
FSQ106N with IMX455 would be great.
Match your gear well, and your results will work out!
