Tulip Nebula Sh2-101 (Widefield)
« on: Jun 13, 2021, 23:56:13 »
Tulip Nebula showing the surrounding gas and dust. Single image with Samyang 135mm lens.
I added some data taken last year with a smaller lens and tried to add it into the mix, so the right hand side has twice as much Ha data than the left hand side.
The little blue reflection Nebula hasn't come out very well, but I guess it's a tall ask from a Camera lens at Bortle 8.

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

Very nice field Carole!  You have mastered that wide field lens.

Thanks Roberto.  I have to say when I processed the Ha on it's own it looked very disappointing and featureless, I think this is why I captured it last year and never finished the job, however adding the Oiii and Sii to it and some processing skills I didn't have a few years ago, I managed to get a reasonable result that I am happy with.
