M45 red sky

Post by Melty »

Hello

First, hello to you all. I'm a new member and thus is my first post.

My trouble stems from trying to process a stacked image of M45 i took a few weeks ago.
M45.jpg
M45.jpg (289.89 KiB) Viewed 8985 times
The image comprises of:

120 60s lights
30 60s darks
30 60s flats
120 bias all stacked in dss (prior configured for Startools)

Sadly, light pollution was a factor, but the moon was also out and pretty bright.

After Autodev, Crop, Bin, Wipe and Autodev ( or a vaguely similar workflow) I'm met with the red background to my image, for which I have no idea to process, or what it means. If it's gradient, why doesn't Wipe do it's thing?

Can anyone offer any support, please?

Cheers.

Try -autodev -bin -crop- Develop -drag the slider up to suit usually 90% ish or post your file too for others to look at ,use dropbox to share .

Thanks for replying.

After another attempt, the best i can come up with is this.

Autodev in all instances seems to turn it red, so I stuck with the Develop module instead. Stretching the image as-is, after crop, bin, and wipe modules were used.

Here is the original FITS file, out of interest. Be interesting to see what someone else can acheive.

Hey thats pretty impressive.

I'll take a closer look at your workflow later.

Nice one!

Not a bad image considering the light pollution.

Here's my attempt https://www.flickr.com/gp/rkonrad/he5276

I'll attach a log file when Christmas is over... generally I like the isolate life module a lot. Try it without a mask.

Merry Christmas to all!

Apart from a slightly different colour temp. that looks similar to my latest effort. Big thanks to all involved. :thumbsup:
