imaged NGC 1788 and LDN 1616 (Halifax)

I had asked the BGO robot to image NGC 1788 and collect data in luminance, LRGB, as well as Hα and O-III. It reported an error, that the session did not complete. Perhaps due to clouds. After downloading the data container, I found the oxygen filter data was missing. Alas, maybe I won't need it. 1788 is a reflection nebula in Orion. Another RASC Finest NGC.

RASC Finest reflection nebula NGC 1788 luminance

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

Look how dark it is along it's south-west edge! Dark nebula! And the lumpy dark material along the bottom-centre of the bright nebula, like brooding thunderclouds. Lynds (LDN) 1616.
