My experience this time round
My SCT does not work think it is the corrector plate, I think the MaK glass will block.
Camera has to be able to be sensitive to the IR/UV definitely no blocking IR/UV which is fairly standard I believe, check the camera specs. My ZWO 178 is not sensitive to IR/UV as far as my results show.
Some barlows are more suited than others ,simple ones are recommended.
I managed to get a QHY5 462 mono (colour does sort of work) and I borrowed a 200 mm reflector and have got to go through all the capture data but in the first near in focus avi run I had stucture in the cloud tops, but do yourself a favour and get a motor focus set up.
I got results a few years ago with the RC and a point grey chamleon cam, which must have been sensitive in the bands needed.
I am sure those that have done more with Venus will chip in later.
