Hello,I'm using Ekos on astroberry with a ZWO EAF focuser, I got for my birthday from my kids. I looked around a bit and these are the settings I've tried (found info on this forum):

  • Settings tab:
    • Full field: checked
    • Box: 64px
    • Annulus: 25% - 80%
    • Settle: 0
  • Process:
    • Detection: SEP
    • Kernel size: 5
    • Sigma: 1.5
    • SEP Profile: focus default
    • Algorithm: Linear
    • Tolerance: 5%
    • Average over 2 frames
When I start the automatic focus process - after I focused manually, it starts far out (or in), with donnut-shaped stars, at some point it reaches (imho) nice focus but continues and stops with donnut shaped stars. I've read somewhere that with a Newtonian it's not easy to use an automatic focus process, due to the secondary mirror shadow when out of focus.Can anybody please advise what settings I can use for my setup, or should I should I forget about automatic focussing with a newtonian?Thanks and kind regards,
