This is one of 2 images of the Butterfly Cluster (cataloged as Messier 6 or M6, and as NGC 6405) is an open cluster of stars in the southern constellation of Scorpius.
The Butterfly Cluster is 1600 light years from Earth. I took this picture August 10, 2024 just after 10pm using my Celestron 8″ SCT with my ZWO ASI2600 MC Pro. The image is 9 60 second subs @ 100 gain at the camera native 6248 x 4176 pixels in Sharpcap. Processing was quick and easy with Pixinsight. I had planned on getting a lot more integration but 15 frames into the imaging session, clouds rolled in. I should have gone with my gut. 2 weather apps made for stargazing and the weatherman were wrong.
If you compare this image to https://modernastronomer.com/2024/06/m6-butterfly-cluster/ you can clearly see why the hyperstar is good for somethings and not for all things. Even though I only needed 10 second subs using they Hyperstar, I had to drop the ROI (region of interest) to a smaller field of view. And it still is not as detailed as this one.
