I have LRGB Astrodon I-series and 1 3nm Ha filter from Antlia. The different between focus points in 1400 focuser steps which makes the local field fail.
What do you guys do in this instance with your setups ?
Avoid different tichkness filter in astrophotography, avoid localfield autofocus for narrowband. isolate the different filter sequence with only this fitler, override the plate solving settings in sequence to use the same filter or otherwise use 2 different voyager profile, one with only the antilia filter and on for the broadband and the same tickness filter
