Seagull Nebula - details in description

IC 2177 a.k.a. Seagull Nebula.

.....................................................

IC2177 is a region of nebulosity that spans about 240 light-years along the border between the constellations Monoceros and Canis Major, at a distance of about 3,800 light-years from Earth.

This is not the first time I have shot at the same targets with both the color and mono cameras, but it is the first time I have used both data sets for a single image. The color camera data was used as the Luminance channel, along with the Halpha data, and for the final result I used an LRGB approach.

Equipment and settings:

Mount: Skywatcher EQ6R

Telescope: Skywatcher 72ED + 0.85 dedicated flattener/reducer

Camera: ASI 533MC pro + ASI 533MM pro

Filters : Antlia ALP-T / Astrodon H S O 5nm

Integration : 42 x 5 min with the color camera / S 26 x 4min, O 40 x 5min, H 21 x 5min

Stacking with DSS/Pixinsight.

Edit in Pixinsight.

Location: my Bortle 6+ backyard.
