Nevay Observation

Line: 64 to 64
  • Not shown in stellarium or clearly in astrometry so took a few tries to get in the right place
  • 10 min Ha showed up something and then realigned using the stars in both the Ha and L images.
  • It's roughly a ring but the 'trunk' is on one side so although I was aligned to the ring perfectly, I offset it to get more of the trunk in field of view.
  • 4x Ha at 30min, 9x L at 120s. In 4th Ha at 4:44
  • Decided to stick with this target rather than trying any others to get as many sub frames as possible to beat the noise.


  • Lastly 60 flats as focussed was changed.
  • 5:52.
