The Great Andromeda Galaxy

 

Really happy with this outcome. This was a tougher object to process so it is especially rewarding.

Supernova Remnant Abell 85

Supernova Remnant Abell 85

This target is probably beyond the capabilities of a One Shot Color camera. This represents just under 5 hours of data. I'm glad I tried as it tells me my limitations.

Sharpless 2-121

Sharpless Catalog 2-171

Sharpless Catalog 2-171, is a star forming nebula located in the constellation Cepheus, ~3,000 light years from the Earth.  A very young cluster of stars known as Berkeley 59, is located in the lower center right of the image.

M52 and the Bubble Nebula

Open Cluster M52 and the Bubble Nebula.

"To the eye, this cosmic composition nicely balances the Bubble Nebula at the upper right with open star cluster M52. The pair would be lopsided on other scales, though. Embedded in a complex of interstellar dust and gas and blown by the winds from a single, massive O-type star, the Bubble Nebula (aka NGC 7635) is a mere 10 light-years wide. On the other hand, M52 is a rich open cluster of around a thousand stars. The cluster is about 25 light-years across. Seen toward the northern boundary of Cassiopeia, distance estimates for the Bubble Nebula and associated cloud complex are around 11,000 light-years, while star cluster M52 lies nearly 5,000 light-years away."

Likely the best I can do with the L-Pro filter.

Limits of One Shot camera with a Light Pollution filter

So I've tested to see just how much detail one can capture before there are diminishing returns on my equipment.

So for me, that includes:

• Bortle 7/8 Skies
• SGO 6" f/4 Imaging Newtonian
  
• ZWO ASI 533MC Pro camera (3.76 x 3.76 micron sensor)
  
• Optolong L-Pro filter

I can't seem to improve details beyond 2 hours on small galaxies or 3 hours on nebula

Here are the results:

Draco Trio of Galaxies

Bubble Nebula

For nebulas, I'm receiving on Optolong L-Enhance tomorrow which will allow the Ha, Hb, and Oiii through.
