Session Notes

IC 2165 - Planetary Nebula (PLN 221-12.1)     NGC 2242 - Planetary Nebula NGC 2301 - Open Cluster (H VI 27)     Photometric Monitoring - Variables    - None     Astrometric Monitoring - Nearby Stars     - None      SharpCap Files (S608)

- Early morning Session (2 hrs duration). Clear skies, low wind. - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Main aims of the session were to acquire images of selected deep sky objects and to test updated routines for initiating PHD2 Guiding from my CCDApp2 Observatory Control Software. The session also aimed to continue testing of dual camera operations using both PHD2 and SharpCap 3.0. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  0°C (minimum) - Notes from 2017-12-22 >>

NGC 2242 - Planetary Nebula

Deep Sky Challenge object in Jan 2018 edition of Astronomy Now magazine.  NGC 2242 is a very faint planetary nebula in Auriga (Mag +15.1 with a +17.6 mag central star).  Discovered in 1886, it was thought to be a galaxy until a study published in 1987 showed it to be a planetary nebula.
