- Post-Midnight Session (6.0 hours) Session operated under automated control Session preceeded by PHD2 testing/tuning - Main aim of the session was to test a number of new program features and to acquire images of a selection of targets     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  Starting at -1°C (min) before rising to +1°C by dawn (Dew heaters on new automated control) - CCD Temperature:  -20/-25°C  (61%/68% av. power) - Notes from 2019-12-17 >>

NGC 2237 - Nebula  (Rosette Nebula)

NGC 2237   (Monoceros) with NGC 2244 open cluster Located an estimated 1,500 light-years from Earth in the constellation Monoceros, the Rosette Nebula is a spectacular region of ionized hydrogen excavated by the strong stellar winds from hot O- and B-type stars in the center of the young open cluster NGC 2244. It is a region of on-going star formation with an age of about three million years.
