Description

The Fireworks Galaxy with SN2017eaw. Sorry for the endless revisions. I believe I got decent data, but I'm having trouble eking out the best from them. Ultimately, I'm pretty convinced that DSS is messing with my color. I think it might finally be time to invest in PixInsight.

B

Description: Revision B has SN 2017eaw marked and is heavily cropped.

M

Description: I added a super luminance using all subframes - I think it brightened the galaxy and made it a little less noisy.

Uploaded: ...

N

Description: Crop with supernova marked.

Uploaded: ...

O

Description: Brightened background, made channel mixer adjustments, noise reduction, slightly tighter crop.

Uploaded: ...

P

Description: Crop of Version O with the supernova marked.

Uploaded: ...

S

Description: I've been struggling with the color of this one since I first uploaded it. I think I finally got it right...

T

Description: Crop of last revision with the supernova marked.

Uploaded: ...

U

Description: I just can't leave this one alone... I finally had the bright idea of combining the dual images by giving the original a 75% crop (instead of a 50% crop) and inserting a cutout with the supernova marked. Should have figure this out 5 months ago...
