Michael created a new topic ' Narrowband: do you use a focus star?' in the forum. 1 year ago

Seem like with my setup i have to run autofocus for each NB filter. Tried multiple strategies (full field/ donut/ subframe)(exposure times) but too often, with autofocus failing often after 20+ minutes, the scheduler aborts...

I would think a slew to a designated bright star would allow for much shorter exposure, and get more reliable results...

Would be interested in your thoughts/ strategy

Thanks,
Mike
