NGC 7239 the Helix.
Hi,
Thought it was time to try my hand at some planetary nebula, imaged the helix and the dumb bell.
The helix obviously requires a lot of data,I did one hour thirty five minutes, probably needs twice that. Still I'm happy with my first attempt.
Telescope 8” f/4 astrograph on a HEQ Pro 5 mount, orion mini guider.
Unmodded Canon 1100D at ISO 800.
19 x 300 sec subs ISO 800,
24 dark frames, 16 flat frames and 11 bias.
Stacked in DSS and post process in Phototshop.
Cheers,
Justin.
