NGC 1003 – Galaxy In Perseus: Observer’s Challenge Report #118 – December 2018

december 2018 observers challenge – ngc-1003

Notes and sketch by Sue French from New York:

I went out on December 4th to observe NGC 1003, which was my first clear, moonless night since October 30th.  Apparently the weather gods have a wry sense of humor, since this was my wedding anniversary.  We took out my homemade 254/1494mm Newtonian (10-inch f/5.8).  The seeing was fair, the transparency good, and the ground was covered with snow. 

The night was slightly breezy and the temperature 19 ºF.  At 68×NGC 1003 is a faintly visible oval near a 10th-magnitude star to its west-southwest.  At 187× the galaxy is nearly uniform in brightness, and a faint star appears along its northern flank. The galaxy looks more flocculent at 299×, and a slightly brighter region rests between the two flanking stars. The sketch was done at this magnification.   Sue French

We also looked at Comet 46P Wirtanen through Alan’s 15×50 image-stabilized binoculars.

Equipment:  SBIG 100E camera and 32-inch f/6 

I could’t use many subs, had some tracking issues and need to work on my declination axle motor to worm coupling. The tracking seems to bounce a bit N-S, and stars are a  bit bloated, so this is not my best effort.  The time was about 40 minutes for a total of 5 min subs only.  Mario
