Hi Tony,
Indeed, happy to help out, though I think we'll both be bouncing ideas and concepts of each other.
I don't know how much time I'll get to use it. I only get down to my dark sky site on weekends. This will change with time however, as I'm progressively setting up the observatory for remote operations. Its damn hard to get internet comms faster than 56k where I'm observatory is located and even then I struggle because of a stupid electric fence interferring.
Hmmm. Filters - nice choice on the Astrodon's. I haven't decided yet so will be looking forward to seeing what you deliver. Custom Scientific aren't bad. I do like the sound of the Astrodon interline filters though. Considering they are balanced i.e don't need different exposure lengths for G or B is time saver.
Interestingly, on the C11, I have enough backfocus to have the Lumicon GEG and JMI NFC with Robofocus to reach focus. This gives me F/4 mode (1120mm) - a decent field of view for the STL11K. I'm keen to try out the computerised focusing accuracy instead of watching FWHM figures all the time.
