The Wizard Nebula
An emission nebula 7,200 light years away and my first proper project of the new imaging year.
Really happy with it as I’ve had a steep learning curve with new kit so really pleased to see this image come together. It’s also the first time I’ve imaged it.
72x180s subs collected over 2 nights 24/25th August in my Bortle 7 back garden, Whitley Bay, England
Calibrated with darks, flats and dark flats in DSS and processed in SiriL and Photoshop.
Lacerta 72mm f/6 APO
ZWO ASI1600MC Pro at -15C gain 200
ZWO 60mm guide scope
ZWO ASI120MM-S guide camera
Altair Astro 2” Tri Band OSC Filter
Data collected in APT and guided with PHD2
Taken on Sunday evening with a 98% Moon.
Comprising of 12 x 600s subs using an ED80 with a 0.85x FF, an Atik 383L+ and a 7nm Optolong Filter.
Stacked in DSS, and processed in PS.
Full frame and cropped, mono and h-alpha colour using NC Actions.
Thanks for looking
To improve my NB processing skills I thought I'd attempt the Wizard Nebula.
The image below is a bi-colour with Ha mapped to red and OIII mapped to blue and green. Since I didn't like the initial colours, I experimented with the Hue until I achieved colours that I liked for the nebula and star field.
Processed in Photoshop CC, CCDstack and PI, the image consists of 30min unguided subs and was taken with my Esprit 150 mounted on my GM1000HPS.
LIGHTS: 16 Ha, 11 OIII x 1800s. DARKS: 30, FLATS:40, BIAS:100 all at -20C.
An LRGB +Ha image of the Wizard nebula. The Ha was blended into the Lum and Red channels. I had quite a processing battle to get (what I hope) are the correct star colours. I found it particularly difficult to get the blue in the blue stars that are embedded in the red nebulosity.
