NGC 7380 - Sh2-142 Wizard Nebula / Ha b/w

Post by Menno555 »

Despite very faint, very high wispy clouds, I took my changes and gathered 6.5 hours (39 x 600 seconds) of the Wizard Nebula with the Optolong L-eXtreme filter last week.
Probably because of that and/or because I'm in the middle of a city with Bortle 6/7, I got almost no OIII in the capture. Nevertheless good data.
I did some experimenting with color channels, a kind of alternative Hubble Palet in this case and that gave me a green/yellow capture with a lot of detail. So decided to convert that into black and white to show it even better.
For me this is my best capture and processing so far :)

I am going to do a color version but I want to add broadband data to it, most likely with the L-Pro. At least I want to included the small white nebula part.

Below is the small version for the forum, the 2500px version can be found here:

Bortle 6/7
Meade LX200 8" f/10 ACF OTA
Ioptron CEM25EC mount (no guiding)
Optolong L-eXtreme filter
Zwo ASI071MC Pro camera

Captured with SharpCap Pro @ -10 Celsius / White balance R50 B50
39 x 600 sec / Gain 200/ Offset 10

Stacked with DeepSkyStacker

Processed with Siril and Photoshop
Siril: auto Histogram, RGB split channels.
Photoshop: placed RGB in empty image color channels, Camera Raw Filter (blacks, highlights, lights, clarity, noise reduction). Converted to black/white, small contrast corrections.
Size reduction to 2500px.
