APT Bahtinov Aid keeps going on the wonk...

[Marci]

One for @Yoddha at a guess, but does anyone else experience a problem with Bahtinov Aid in APT (v3.50 in this case) where, if using image preview in 1:1, when you hit recalc (or the next sub comes in from the camera and it recalcs automatically) the red cross goes on the wonk and thus provides a duff focus measurement? Only way I’ve found to fix is flip preview back to 'fit', recalc, then back to 1:1. Makes for very infuriating focusing... and occurs with any combination of mask, camera and scope (tried changing all to rule out).

See attached vid for demonstration (problem occurs at 47secs):

Hi Marci,

This happens from time to time. There are two ways to fix stretch the image via Histogram or use longer exposure in order to get longer spikes. The other way is to rotate the mask a bit. You can also try combination of both ways too
