As for setting it up, it is a matter of plugging in the PCI card, installing the driver, plugging in the power and interface cable and running Maxim DL.
It is pretty standard after that.
I have had this on the C9.25 and a Lomo 4" triplet. Nice large sensor. I did use it only once with a filter wheel and there were no probs. It is setup to just use single filters from memory if you don't have a wheel.
It is threaded on the front, I'll have to take a look and see what the thread is, but it is pretty standard, no funky adapters required.
This unit was actually Brett's camera (Bert) as I swapped my Quantix for his a little while ago (due to Brett not needing one with a Shutter) so he has used this particular one more than I have.
The cooling is amazing and the large sensor is lovely, especially for narrowband work from the suburbs. I'd keep it if I didn't have too many kids
