Description

I did the rosette nebula again, with new data and with my 'new' ASI 294mm Pro. I shot with NB 3nm SHO Optolong filters and RGB with ZWO filters.
In total for approx. 40 hours under a Bortle 5/6 sky. I used my Skywatcher Esprit 80 on an EQ6R mount, guided via a ZWO OAG.

Light frames in NB are 600 seconds each and 60s for RGB.
Calibrated using Darks, Flats, Darkflats around 30 ea.

NGC 2237/2238 / 2239 is part of the diffuse nebula  located in the constellation Monoceros region of the Milky Way Galaxy,  also known as the Rose or Rosette Nebula (Caldwell C49) because of its characteristic reddish colour due to the emission of ionised hydrogen gas from the ultraviolet radiation of the cluster's hot young stars. NGC 2238 is considered a relatively young cluster, with an estimated age of a few million years. The cluster is located about 3,000 light years from Earth and has an apparent diameter of about 40 arcminutes.

The nebula has an angular diameter of 1.3° and is located at a distance of 1600 parsecs (about 5200 light years)[2] from the solar system; it has an approximate size of 100 light years.
Was Discovered by John Herschel
