Thanks for the compliments on the website. I've seen traffic more than double every year with a steady clip of a few thousand every week now from all over the world. Just shows how many people really have a desire for Mac applications. Thanks to the INDI community there's support now for the majority of the hardware on Linux and Mac.

Regarding the filter wheel. I too would occasionally shoot all one filter each night, especially when doing narrowband. But recently I started returning to sequences that rotate the filters every hour so that I could refocus, and maintain an even number of frames per object if I got caught up with a string of bad weather. But it's those sequences that started messing up the flats, and I didn't realize it at the time until this post where I started to examine what was happening very closely. If I did a sequence of 30 2 min HA, SII, and OIII, and set it to repeat each night, after finishing OIII the filter wheel would move in reverse and stop at HA. So half my frames would have the filter wheel orientation from clockwise approach, and half from counterclockwise approach, and I was never able to fully remove the dust motes. I just thought I was doing something wrong. But now, with unidirectional movement enabled, I'm pretty confident I will be able to do sequences with no problem.

Just need to get that updated driver installed.
