Log

20:00 - Set up computers

20:15 - Moved large ladder out of dome, removed LED from Picsarr

20:20 - Dark calibrations

20:23 - Reseated LED

20:24 - LED calibrations

20:30 - Set up dome, opened dome, opened mirror doors

20:35 - Slewed to Arcturus. Saw what may be Arcturus through the finder but could not match it with Picsarr

20:45 - Slewed to Vega. Could not confirm Vega in Picsarr

20:50 - Used Astrometry to point. Successful :)

03:44 - Light cloud cover rolled in.

03:49 - Target is no longer visible stopping observation and waiting to see if it gets better.

04:16 - Target is still not visible, went to the roof to check: thick cumulus clouds, nearly no patches of clear sky. Beginning shutdown procedures

04:19 - Shut down complete, leaving 433C

ToDo

Notes

  1. Telescope slews diagonally regardless of where we are pointing in the sky
