I have been running several sessions with L, R, G, B, O-III and Ha with great success, where Astroart has been FF autofocusing automatically for each filter.
However, I recently added a S-II filter to my filterwheel, and it has a relatively large afocal distance compared with the other filters:
Code: Select all
Filter Pos Relative L 3609 0 R 3605 4 G 3606 3 B 3602 7 Ha 3616 -7 S-II 3291 318 O-III 3614 -5
Is there any way to let Astroart know the relative focus positions in order to aid the FF AF?
