Focus assist assistance?

[Oberon510]

I have been using the focus assistant on a 10" SCT with a Moonlite focuser, a reasonable size star and FWHM measurement. It seems to be off a bit and wondered if others have any focused advice (sadly pun intended ).

See the photo below with the left side using the SC focus assistant resulting in a SC best focus position of 4239 on the Moonite and the right side is my manual adjustment which ended at MF position 4140 (max MF focus is 0-6250)

Appreciate any suggestions you may have.

Thanks,
Ken

Hi,

could you share a screenshot of the focus graph that SharpCap draws as part of the focus assistance procedure please? It will look a bit like the one shown in the documentation here : https://docs.sharpcap.co.uk/4.0/#Point% ... 0Detection

It would also be good to know which focus score tool you were using and what settings for it you have selected.

thanks,

Robin
