The andromeda galaxy

"Second light" image from my new observatory, with guiding and dew heating.

    Guiding

  • Lodestar SX (borrowed from Bas - thank you!)
  • WO-Guide scope 200mm F/4
  • INDI 1.2 on Linux/Debian
  • PHD2
    Imaging

  • Dew heaters on guide scope and telescope, powered by lab supply
  • Canon 6D, capturing controlled via gphoto2, on Linux/Debian

Polar alignment is still way off, and this mount has a wicked 90s periodic error period with large amplitudes, and as a result, PHD2 had a tough time keeping up with the corrections (the graph would swing wildly between +- 3 arcseconds - though the end result is not so bad. Judging from the shift in image in the course of almost 2 hours, there is either still flex (guide scope attachment?) or the camera attachment is loose. Probably the last one.

Conditions were horrible. A lot of fog and moonlight, at the end of the session everything was soaking wet.
