Hi
I imaged NGC 3576 in Carina back in June , just finished putting it together. I tried using a UHCS filter for the colour images, seems to keep the stars a little smaller. First time I have used a off axis guider, this let me increase my subs from 3 min. to 10 min. compared to guidescope.
16" F5 NEWT, coma corrector, OAG UHCS filter, Ha filter, ST4 auto guider,
QHY8 camera,
Exposure details: RGB 1.5 hours, Ha 2.5 hours, processing in PS
clear skies,
