Here is a new color version of the supernova in M101. In this version I was able to get subframes using Red, Green and Blue filters to create a full color image. The image below used the Luminance image for my first post and combined in the stacked images from the RGB filter subfames I took on the night of May26th/ the morning of
May27th. I was planning to get some Hydrogen Alpha data to include in the image, but the clouds have decided otherwise. Hopefully in a week or so the skies will give me a break to get some more imaging done.
All questions comments and suggestions are welcome.
For information on the Luminance only image and the supernova see

A slightly less compressed version of this image without the arrow pointing to the supernova can be seen and or downloaded from my website at.

(All downloads from my website are free). It is still a work in progress so if you run into any issues using it please let me know. Note: If you zoom in on the image in the website it may take up to 30 seconds or more on some image to pull in the full resolution image.

For those interested this image was taken with a Meade LX 200 16 inch Schmidt Cassegrain with a focal length of 4064mm using an ASI 6200MM pro monochrome camera with 1x1 binning, the gain set to 100 and the temperature set to -20C for the Red, Green and Blue images. The exposure length for all the RGB subframes were 300 seconds long.

Red 22 subframes used
Green 22 subframes used
Blue 20 subframes used

Total exposure time include luminance from the previous post was - 7 hours and 8 minutes.
All appropriate Bias, Flat and Dark frames were also used in construction of the image.
