9 shot manual stack in PS7 of the Ring Nebula - M57 - in Lyre.


Subs were limited to 30" due to dec drifting badly even with guiding so ISO had to be turned up to max - 6400

  • Imaging: C8 XLT, CG-5 GT, Revelation Superfocus 2" R&P focuser, Canon 1100D (unmodified), 1.25" UHC filter.
  • Guiding: Travelscope 70, Orion StarShoot AutoGuider, PHD. (something not working properly here as dec drifting very badly!)
