Hi. I've found a bug in the Sequencer FF Autofocus. Basically, it drives the focuser to the zero position when it starts, which typically drives it completely out of focus.

Example: Focuser is perfectly focused at position 14725 prior to starting Sequencer. As soon as the Sequencer calls FF autofocus, it drives the focuser to the position 00001, which leaves the image complete out of focus when the images are downloaded.

The strange thing is that when FF Autofocus is called from the setup tab, it works perfectly, so the bug is related to how the Sequencer interacts with FF Autofocus.

thanks

Hi, did you set the special position 99999 to launch autofocus in the Sequencer?

Mea Culpa....

I was putting in a 1 for 1 iteration of the FF autofocus, which was my mistake.

I'll try it again tonight.

However, I did discover that if I tried to use a 50% subframe with FF autofocus that it would create an exception error and I'd have to close AA7 and restart it.

thanks.

OK, I used 99999 as per the documentation...and FF AF is now working extremely well.

more later.
