Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

Melotte 15 - The Heart of the Heart Nebula (IC 1805) - 5.5 hours of SHO

Melotte 15, better known as the “Heart of the Heart,” is an open cluster with emission and reflection nebulae that creates an interesting structure that can be found in the center of IC 1805 - the Heart Nebula.

This rich region is located about 7,100 light-years from Earth in the constellation of Cassiopea.

This is image is the result of 5.5 hours of narrowband data collected on my William Optics 132mm FLT platform using a ZWO ASI1600MM-Prop camera.

NGC 7635 - The Bubble Nebula w/M52 - 8.25 hours in SHO - Not Sure I Love it.

NGC 7635 - The Bubble Nebula with M52. 8.25 hours in SHO.

This image was shot on my William Optics 132mm FLT APO platform, using a ASI1600MM-Pro Camera and the IOptron CEM60 mount.

The original goal was to do a deeper integration of at least 15 hours - and while the weather would have supported this, I missed two clear nights due to illness.

This image has a very high color and contrast position - almost too high for me, but I disliked the lower contrast and saturation versions more - so this is it. I am not sure I love this image….

Messier 8, 20, and 21: A Rich Region in Sagittarius - 3.9 hours in HaRGB

This imaging project is a group photo taken in a rich portion of the constellation Sagittarius. It is the result of just 4 hours of LHaRGB integration. In this group, you can see Messier 8 (The Lagoon Nebula), Messier 20 (The Trifid Nebula), and Messier 21 ( Webb’s Cross). Also seen is the “Fist” shaped nebula on the upper left that is most strongly associated with IC 4685. This was taken with my Askar FRA400 widefield scope platform.
