Now that I have just started getting into narrow band imaging I am having quite a battle getting the settings on the "Autofocus window" in Sequence .... especially when trying to use the Oiii and Sii filters. I don't seem to have any problems with all other filters.
I am using an APM 123/738 scope with an Optec FeatherTouch FTF3545 3.5-inch focuser attached.
Is there anybody out there who can either send me a screen shot of a working Autofocus setting screen ( or simply list the most suitable settings ) to be used with the Oiii and the Sii filters.
I keep wasting precious clear skies here in the UK with this issue :-(((
Any help with this would be VERY helpful.
