Yeah... I used separate 7nm Ha and OIII filters with my QHY8 in 2008, then went to the SBIG ST8, then ST10XME with SHO filters, then went back to a colour camera, then got an SBIG ST8300M that I had from 2011 through to 2023, I just got annoyed with the weather last October/November/December, when I couldn't for the life of me make a full colour image, because the weather would turn bad for nearly 3 or 4 weeks at a time, and I'd have L, R, G, but no B... I think in those 3 months, I achieved 1 LRGB image of M45 (much less integration than I wanted), other than that I had 8hrs of M78 L that I never got any RGB data for at all... I got really mad and sold the mono camera in favor of a an OSC camera.... and largely, I've been perfectly happy with it.. My only issue is that I find myself having to capture 15~30hr data sets in Ha/OIII to get a reasonable image when I could have done it in 3hrs Ha, 5hrs OIII with a mono camera.
I've been toying with the idea of a mono camera just for narrowband imaging, and having the OSC camera for everything else... I know the difference isn't THAT massive, but I find the data from a mono narrowband image is FAR easier to work with than OSC dual narrowband (Especially now that I have Ha/OIII and SII/OIII, I'm looking at 40hr integrations to get a decent amount of data to build an SHO image...
I'm toying with the idea of a 533... The options are tricky... I love my 294, but its not without its issues, and I don't think that I want to deal with them in 2 different cameras, the 533 sensor is a little small for my liking (especially with my 840mm focal length), but the 571 is INCREDIBLY expensive once you get a 7pos filter wheel full of filters...
I wouldn't mind finding a used KAF8300M or KAI11002M camera...
SO many options, I typically find it too difficult to make a decision haha
