Hubble Palette Skull (Rosette) 130m : Ha30/OIII30/SII70

[dylan_odonnell]

Here is my second try at HST palette narrowband but this time using my QHY12 One Shot Colour CCD. The target deserves longer than the 5m/300s exposures I used (and more of them!) but am pretty happy for a single evenings imaging over a couple of hours.

Darks applied, no flats or bias. Stretch & Star Reduction in PixInsight. Channels, Levels and Noise Reduction in Photoshop.

Celestron Edge HD 9.25" / Hyperstar III lens + filter drawer system / Baader F2 high speed Filters / EQ6 Pro mount w/ EQMOD, Stellarium & Astrotorilla. Acquisition and stacking in Nebulosity 3 & 4.

Looking good with some great resolution :)

Thanks Colin! Yeh the QHY12 chip is huge. It would be a clearer image if I had a mono CCD for the narrowband filters of course. And there was a light breeze throwing things around by half an arc second but I'm pretty happy for a quickie :)
