Evf not focusing

b1ues

Hi, i used my Evf with ASIAIR plus well last season, however, this season I have rebuilt my rig and tried to use..strange thing, I manually get close then start the autofocus program on the ASIAIR plus, but the stars end more out of focus..even though the program says it’s good!

anyone had the same issue or know any fixes?

b1ues unfortunately, i don’t know any fix yet. But i have problems with EAF not focusing correctly as well. The problems started with the ASIAir app v1.92 (iOS) and its corresponding firmware. Before, i could let the filter change during autorun and it focused correctly, now most of the subs after the filter change are out of focus.

This is another reason why I have stopped using the ASIAIR pro. I am now using NINA and PHD2. Autofocus and guiding are 100% better.

b1ues Upgrade to the latest version of EAF Firmware to try.
Could you also check the AF curve and take a screenshot?
