Hi Pierre
Thanks for the details on the correct metal back distance of 56mm.
I have the Moonlite focuser fitted on my M180 and although I have a Tak adapter that couples my SBIG ST7 to the Reducer/Flattener, I do not have sufficient in-focus travel to focus when using the Canon 40D. I estimate I am approx 2 or 3mm short?
So, I cobbled together a few threaded adapters and have used this – I will go and measure the spacing to see how far off from 56mm I am.
The coma didn’t show itself on the (smaller) 765x510 pixel ST7, but I was expecting some to appear with the 3888x2592 chip of the Canon 40D.
Cheers
Dennis
