Title: Tulip Nebula Sh2-101 (widefield) reprocessed
Post by: Carole on Aug 24, 2022, 12:05:55
I was never happy with my original process of this, goodness knows what I did as it is pretty awful, so decided to take another look at it today. 

It's still far from good, but a darn sight better than my original process. 

Original info:
Ha 20 x 600secs on Left and 43 x 600secs on the right. Baader 7.5nm
Oiii 16 x 300 binned x 2
Sii 13 x 300 binned x 2

Atik460EX and Atik428EX with Samyang 135mm F2 lens @ f2.8

HEQ5

Total imaging time 9h 35m (imaged from Bromley in June 2021

Thanks Roberto, but it wasn't just the green, I had lost much of the detail (goodness knows what I did it's too long ago) and the stars left much to be desired too.

Yeah, much more detail, and the stars aren't saturated, either.

Yes ~ much better Carole.  More detail and so much more dramatic!
