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
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.
An LRGB +Ha attempt at the Wizard nebula. I used the Ha as a booster for Lum and Red channels. Due to the combination of bright stars and bright red nebulosity, I did find this quite a challenge to obtain some (hopefully) accurate star colours. I've concluded that blue stars embedded in red nebulosity are difficult to process !
The image represents just over 13 hours integration time.
Comments and criticisms are welcome.
LIGHTS: L:9,R:8,G:7,B:8 x 600s, Ha:16 x 1800s. DARKS:30, FLATS:40, BIAS:100 all at -20C.
