Yes, it is an RC scope alright, a 4 Metre one, bigger than the 3.9 metre AAT. The AAT has an F1 focal reducer system, imaging how deep that could go, though I dont know how big a corrected field it gives.
Note. Ive actually seen the brightest part of CG4 visually, at the inagural SPSP many moons ago, through Peter Brobroff's 20 inch dob, I verified it for him, confirming we both could see a definate nebulous area near that galaxy. I then pointed the ANSW's 16 inch dob to the same area and could see it there too!

Thanks Scott and you are right, imaging over such a long period from East of the Zenith down to nearer the western horizon (didn't go below 25deg) does throw one challenges in processing but honestly the gradient damage done to this image wasn't too bad (although Jase just "had" to find its remains and make it known didn't he
) becasue I tried doing as much of the colour gathering at higher elevations.
I believe you regarding seeing the brightest bit visually but the Halpha was bloody faint I can assure you, 8hrs was probably really only half of what I wanted with the KAI11002 chip and using 10min subs.
