Hi,

This image was three years and a comedy of errors in the making. It is an image of globular cluster M15. It is a globular cluster about 33,000 light years away in the constellation Pegasus. It is estimated to be about 12 billion years old, making it one of the oldest known globular clusters.

I took the original subs in 2017 using the Apogee CG16M I had at the time. Fast forward three years and I noticed I never finished it so I got the remaining frames. Unfortunately, I set the green frames at 500 seconds instead of 300 seconds like all the others. So, the outcome is an image taken with two different cameras and two different exposure times. I am not sure if it was worth all the drama but I think it turned out pretty good.

Comments and suggestions welcomed.

Looks really good, two cameras, multiple exposure lengths and all.

Hi,

This is an image of SH2-132, also known as the Lion Nebula. This version should probably be called the Lion Head Nebula since that is all that is in the FOV. I would need a mosaic to get the entire nebula. It is an emission nebula about 10,000 light years away in the constellation Cepheus. There is a prominent dark nebula along the left side of the image as well as some Bok Globules near the center top of the image. This image was captured with 3nm narrowband filters (Ha, SII, OIII) and processed with the SHO palette with RGB stars.

Gregg,

Really nice work. I would never have guessed there were that many objects in the FOV without the map. On my monitor there is a green hue on the right side of the image. You might try HLVG if you have it or SCNR in Pixinsight.
