Iris Nebula (NGC 7023)

Recommended Posts

This blue reflection nebula in Cepheus is a great target and one that I haven't tried with my new Zwo ASI294MC Pro. The difficulty I had previously was trying to get those dust lanes surrounding this nebula.

I used my SW200P on a HEQ5 mount and acquired 32x lights (800sec duration) in conjunction with an IDAS light pollution filter (I live in Bortle 5/6). The OSC camera was at default unity gain and off set.

The images were stacked in DSS with usual calibration frames and processed in Photoshop CC.

I think I got those dust lanes!!

CC's welcome.

For Comparison the image below is my old one (with a DSLR Canon 650D):

Excellent, I've been trying this for the last few sessions from a bortle 7 so it's a bit of a challenge, has to be stretched to within a inch of its life to get that dust.
