My Ultimate Image Of The Horsehead Nebula: By Guest Host, Mario Motta

November 24, 2020

I did a 4 hour exposure (32-inch telescope) of the horsehead using 6 filters. Ten days I ago spent 4 hours obtaining a new horsehead nebula. This is using 6 filters, red, green, blue, but also Ha, S2 and O3. Using narrowband is tricky for color balance but using the RGB helped that out, and got the intrinsic resolution enhancement of the narrow band filters. Been busy, so finally processed this weekend. My previous image was eight years ago only RGB. There is significantly more detail in this image than my prior. I had to play with the six different filter stack sets to get just the right balance of detail and color.

If anyone wants to see my collection of over 600 images, broken into messier, NGC, IC, etc, go to:

Thank you, Mario Motta
