M1 Crab Nebula

[Star101]

I aim to image M1 a few more times over the coming months as an ongoing project. Its a bright nebula and easy to image. I'd like to get as detailed a picture as possible.

I do have more data. This data is from Monday night. I used the new WeightedBatchPreprocessing Script in PixInsight to process. I can't see much difference when I used the old BatchPreprocessing script but I find I do actually prefer this image over the other made the old way. Thanks PixInsight

Anyhow, here is Monday nights M1 processed the new way. 

Thanks for looking.

I like the colours.  It seems to give a nice 3d feel.

Thanks don41. Thats what I am trying to get and improve on

I like this a lot.  The threads of Ha are exquisite!

I decided to process the subs I had collected. I used blink to remove 4 that had clouds. I set the PixInsight script WBPP to do its thing. It finished with 6 subs integrated. Not great when I started with 34 subs lol. So, I blink checked all 30 subs that had managed calibration and found 2 that didn't look good so removed. Than run the star alignment and finally integrated the 28 remaining subs. A gentle histogram stretch, curves and the minutest deconvolution, standard settings for ACDNR and finally SCNR Green to get this image. 

Taken over several nights in November.

Very nice indeed David.I have just had ago at this myself,but on a much smaller image scale than your rendition.I do like both images,but in my humble opinion I prefer the bottom one.

Thanks Mick.

Yes. the first (top) one is only 12 x 600s. Whereas the bottom one is same data as the top one but another 16 x 600s. A total of 28 x 600s subs. combined.

I read that there comes a point of little return and 30 subs is about it for CCD's so I think that bottom one, my M1 is done
