Last time I wrote about imaging the Cygnus Wall, part of the North America Nebula. I did get about 7.5 hours of integration time in the HaOiiiSii (Hubble palette) and RGB stars, but the post-processing of the subs is giving me a whole bunch of trouble. So while I'm still trying to get this done, I took a break and decided to process some of the simpler objects taken with the standard RGB color palette.
First up is NGC 6712, a small globular cluster in the constellation of Scutum.

Next, another globular cluster, M71, in the constellation of Sagitta. M71, or NGC 6838, is a star cluster at a distance of about 12,000 light years away from Earth and spans some 27 light years across.

Finally, my first dark nebula, is LDN 1165, in Cephus. Nebulae are giant clouds of dust and gas. Dark nebulae have a higher concentration of dust, which blocks almost all the light from the background stars, thus producing a region of the sky that is dark and featureless - what appears to be a hole in the sky.

With the cloudy nights coming up, I think I'll be able to complete the processing of my other images. Stay tuned.
