  Back to M27. Here is an unexpected 42min-long shot.

   

   

  Place : Médonville (France, 88)

  Date : 2019-08-25 around 4:00 AM.

  Scope : Intes Alter M603

  Sensor : Canon EOS1100D Astrodon inside + UHC clic filter

  Mount : Sky-Watcher HEQ5

  Exposure parameters : 1600 ISO, 42 min (single shot)

  Autoguiding : Sky-Watcher Evoguide 50 ED + Lacerta MGEN 2

  This picture was an "accident". I planed to take a series of 10 exposures of 10 min each, but I started a "no limit" exposure from my computer (Canon dslr connected to a laptop running EOS Utility). When I came back after 45 min, I realised my mistake.

  Here is the result of this 42 min long exposure...

  I plan to take a series of 10 min-long exposures, to compare the result with this single 42 min-long shot.
