am not so sure about this only for f/5 stuff seen as the baader MPCC corrects f/4 through f/6?

I don't see any adapters for CCD's and the only way to connect them seem to be through the 2'' barrel adapter for the corrector.

this look more and more like just a DSLR flattener

lucky then that it was the Uni's CCD and not mine. I only have a DSLR and i know it works with that

just back from an astro weekend with the uni

got this corrector on monday from FLO (wonderful people)

but i couldn't get the CCD in the right place!

it was way to far, from where i thought i should be (about 55mm) adn it don't fit the thread on the front of any CCD camera

I also don't seem to fit the threads on the filter wheel either????

which is that 2'' threaded M48 stuff i think as well

i think i might need to get an adapter made to fit it.

when it was in my 10'' f/4 it made the coma worse, and yes i know meant for f/5 and the distance was off too.

am sure i can get a few pics to show, but i am sure it needs an adapter for CCD's perhaps SW have one on the way?

the ASA reducer should work. It will illuminate a 20mm field. A canon SLR has a 20mm length on one side. So it should flatten axross 20mm , but vignetting may be present. You need a scope of good optical quality, and make sure you have plenty of back focus. The 2" corrector is around 600 euros and offers 0.73x reduction. Its probably the only thing that will work with a decent corrected image circle
