Crab Nebula M1 - more data from March!

Well, bit of a mixed bag with acquisition the last few weeks, but I got enough data together to feel I had the start of something.

Acquisition was my usual setup: Sky-Watcher 200PDS on an EQ6-R Pro mount, OAG guided with an ASI174MM Mini, Baader LRGB filters, Steeltrak focuser and Sesto Senso focus motor, Tele-Vue Paracorr coma corrector, ASI183MM-Pro at -10c as imaging camera, KStars/Ekos and INDI software. Postprocessed in PixInsight, with a pretty "standard" processing workflow - I used local normalisation and as an experiment processed entirely as 64-bit floating point data. No deconvolution, just DBEs and a bit of denoising with masks etc, followed by some masked colour saturation and curves to really draw out some of the finer detail buried in the core without oversaturating (I hope!).

Definitely much more pleased with this than the previous attempt using only a night's data.

very nicely done, great colour especially in the stars

That's a very nice image. I'd be happy with that!
