David's Astronomy Pages CCD Images - Session 37 (2003-01-04) Images (S32)   Images (Main)   Home Page   Images (S38)

Notes (S00037)

This imaging session was of nearly 8 hours duration and ran many under unattended script control.  With ambient temperatures of -5 deg C attended operation of the telescope would just not have been possible.    A number of check visits were made to the observatory  to check progress.   The first visit showed that the telescope's sky position  had become lost due to an inappropriate sync following a SBIG driver: A/D timeout. # 800407DD problem.  The script was restarted and then continued without requiring any form of intervention  for 6 hours 40 minutes, during which scripts took a total of 596 CCD Images as part of the following set of tasks :

• Images of 19 variables in constellations And, Peg & Lac

• Jog Testing (on And R and And RX)

• Images of 16 variable stars in constellations Cam, Per & Tau

• 8 x 9 Mosaic of open cluster M45  (Pleiades)

• Images of 10 variable stars in constellations Aur, Gem, Mon & Cnc

• 5 x 5 Mosaic of open cluster NGC 1807 / NGC 1817 

• Second 8 x 9 Mosaic of open cluster M45  (Pleiades)

• 7 x 6 Mosaic of double cluster NGC 884 / NGC 869

• 5 x 6 Mosaic of open clusters M35 / NGC 2158  

• 4 x 5 Mosaic of galaxy cluster / galaxy NGC 507

• 3 x 4 Mosaic of galaxy cluster / galaxy NGC 1275 (Perseus A)

• 7 x 10 Mosaic of cluster & nebulosity IC1848 

• Image of galaxy UGC 4047

Variable Stars 

Variables in Pegasus, Andromeda, Lacerta were imaged using Automated Scripting (see Scripting).  New set of variables in constellations Auriga, Gemini, Cancer, Camelopardalis, Perseus and Taurus were commenced.
