A Perspective of M57 - The Ring Nebula

Recently one of Insight Observatory's generous Patreon supporters, Luis V., requested a dataset of M57, The Ring Nebula, from the 16" f/3.7 Dream astrograph reflector (ATEO-1). After processing the data myself in CCDStack for him, I realized how good the data of M57 really was. Unfortunately, my processing skills don't come close to what most astrophotographers are capable of doing with good image data. Therefore, I shared out the dataset of M57 with Utkarsh Mishra, one of Insight Observatory's Starbase dataset subscribers who is also an accomplished image processor.

What surprised us both was that with such a small amount of data, Utkarsh was able to pull out so much detail of the planetary nebula as well as the background. Utkarsh processed close to only 4 hrs of data acquired from the 16" f/3.7 reflector remote online telescope. 1 hour of Luminance, 50 minutes of Red, 40 minutes of Green, and 45 minutes of Blue (all binning 1x1). He also added H-Alpha data from the 2 meter Liverpool telescope at 120 seconds with a 35% blend of RGB from the telescope. The H-Alpha data exposed the outer part of the Ring Nebula much more than the LRGB data from ATEO-1 could do alone. The 15th magnitude spiral galaxy IC 1296 is also visible just to the upper right of the nebula in the cropped frame above. The software applications used by Utkarsh for processing were Pixinsight, Photoshop CSS and DeepSkyStacker.

  1. You can see the star glow at the edges of the frame from the 2 bottom stars in Lyra. Very wide field of view this telescope has!
