Sculpted Helix
Hello All,
Sharing a couple of pictures I imaged during August.
The Helix nebula is a bi-color narrowband combo consisting of 2 nights total 16 x 1800s HAlpha and 2 nights of OIII totaling 16 x 1800s ISO 800.
The Sculptor Galaxy was 2 hours of 10 minutes 2 nights trough the Moon & Skyglow filter 600s ISO400 subs.
After the Helix nebula drifted into the meridian extremity where I had to do a meridian flip, once it was done there was no guide star in the OAG so that was it for a nights of helix exposures, but luckily I did have a guide star when framed the Sculptor Galaxy just off center.
The Sculptor galaxy was vertical in the frame and edge to edge. I didn't want to change the alignment set for the framing of the Helix nebula to continue the exposures the following nights so I just imaged NGC253 and cropped & rotated it after stacking and processing.
Both images were exposed at the SCTs native 2000mm.
