M27 also known as The Dumbbell Nebula is a planetary nebula in the constellation Vulpecula. This is a beautiful and vivid target that is large and bright and easily visible through binoculars. M27 is about 1227 light years away.
The nebula is illuminated by a white dwarf star in the center.
This was the first planetary nebula discovered by Charles Messier in 1764
I wanted to have a lot more data with this target. However, when I setup up my scope for this night, I discovered that the apartment complex that I recently moved into had sprinklers set up all across the field. After 5 frames, I heard the sprinklers go off and I had to pick up my gear and move to a dry spot, thus ending my night.
I had to use an Optolong L-eNhance 2" filter due to the moon being at 97% and my setup being under Bortle 6/7 skies.Processing Info
I stacked the 5 light frames along with 40 dark and 50 flat frames in PixInsight
The following processes were performed in PixInsight:
- Dynamic Crop
- Automatic Background Extraction
- Background Neutralization
- Photometric Color Calibration
- MultiScale Linear Transform
- Histogram Transformation
- Curves Transformation
- HDR Multiscale Transformation
Once I found what I liked, I saved the files and went to Photoshop and ran Topaz AI DeNoise. This is an amazing plugin that works like magic.
