revisited NGC 2022 (Halifax)

The RASC Finest NGC planetary nebula 2022 is one of the first targets I imaged with the Burke-Gaffney Observatory system. We've come full circle. Orion is back.

I was trying to get more blue data. My last images were from March 2016 when it is getting low. In fact, I deleted a job in late March and missed out on ionised oxygen data.

Well, this time I captured all channels, luminance, red, green, blue, O-III, and hydrogen alpha.

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Blue only, 60 seconds subexposures, 5 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

O-III only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Hα only, 60 seconds subexposures, 20 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Overall, the quality of the data looks good including the blue filter. And now I have O-III and Hα so I should be good to go.
