M5 Globular Cluster

Unread post by menardre » Sat Jun 27, 2020 9:57 am

I was able to get out last night to image M5. I picked M5 because it is in a good part of the sky and I wanted something with a lot of stars so I can work on my procedures for aligning the LRGB images. The night sky was a bit mirky with fairly high humidity and 1st phase Moon. This is my second real attempt at imaging with monochrome camera (ZWO ASI 1600). I attached it to 5 inch refractor. I took 45 luminance images of 1 minute and 25 images of 1 minute in each Red, Green, and Blue filter. I then used Images Plus to create LUM, Red, Green, and Blue masters as well as align each of the masters and color combine them. This time I did a better job of aligning all of the luminance and color masters. Attached is a slightly cropped result. Only did minor color balance and background flatten. Much better registration this time. Image processing LRBG images is a bit more complicated than one-shot color images, but I am making progress.

Great job Roger, despite the not stellar conditions. Nice improvement in processing over M27.
