Thanks Ray –
As usual, an excellent response to my recent PEMPRO concerns. I have filed this gem away on my hard drive, for future relearning, or if I have another senior moment. Wish you would had written a book about the amazing things your PEMPRO already takes into account – but then you risk giving away too many valuable design details. Obviously, you have thought out almost everything that could go wrong during polar alignment. That is why I feel PEMPRO is an exceptional program which should be in everybody’s telescope software toolkit.
As for MIN-MAX star brightness settings, I have never looked at them, and just trusted your defaults would be fine, left as-is. But, I will consider them further, on another hazy night.
Learned a lot from this mini-lesson.
