Ninas offset plugin is super easy to get this done automatically as you mentioned 😊

This good stuff, but in the end i recommend running autofocus on filter change . Your are not likely optimally focused anyway due to falling temperature!

Hi! Really interesting information. I run one filter (or no filter) on an OSC camera. When discussing with my sales rep they informed me to deal with the filter offset via shims that I’ve placed on the camera, behind the spacer. They indicated the filter would require a chance to back focus. This effectively pushes my camera sensor back by the amount of offset specified by the filter manufacturer. I do not have offsets defined (Ekos). Once my OAG camera is focused I generally do not need to touch it. Autofocus is working fine with filter and shims. Removing filter (filter drawer, not automated) and shims does require an OAG refocus. Would you recommend that I begin using software offset configuration or is what I’m currently doing equivalent? Did they give me bad info? My results have been good so I have not pursued any changes. Thank you, Cheers!

Good but better to just keep it simple, run a single filter per night and adopt a slow burn multi-night project mentality. Ha one night, Sii another night and Oiii when the moon is down. KISS. These targets only really begin to look a cut above the rest at around 25+ hours total integration time anyway.
