What I do in PEMPro V2's polar alignment feature is I let the user select a star
toggle quoted messageShow quoted text
(any star) and I show them the direction that the star should be moved. You can
then toggle between the current position and original position.
As a future feature I'm planning to add sound effects so that as you adjust the
mount closer PEMPro will beep faster and higher pitched until you reach the
correct position. This allows you to make the adjustments right at the mount
without having to go back and forth from the PC.

Yep, I use the full crosshairs align on PAM as well, but it's tricky
if your initial pointing is bad enough that the bright star you're
supposed to be centering starts off screen.
There's no directional indicator of which way you're supposed to be
moving the stars on screen, plus you've no way of knowing if you
Tricky problems, but not insurmountable - they could add a "platesolve
now" button which updated the movement instructions to give you an
idea of how much further you have to move.

I use PAM all the time to refine the (already wonderful) initial
polar alignment of my (cough) Takahashi EM200 (sorry) using exactly
the method you describe. Note that you need to use the physical
alt/az adjusters to make the necessary adjustments in the
the keypad. Anyways, if you have any question about this method, <mailto:ap-gto%40yahoogroups.com> , "Dean Salman" <cluster@> wrote:

Well I got a nice suprise last night when using CCD Commander. I
the program do what it wanted to get the exposure for the guide star
through the H-Alpha filter and it was around 18 second exposure. The
tracking was perfect with the largest error reported 0.2 I did use PAM
to polar align and was within 50 arc seconds in both directions, so
that helped. method
As for PAM, I am not having much luck in using the crosshairs
and moving the mount to polar align. Darrell told me he just does a
run and make an adjustment. Then stop PAM and run it again. This PAM
worked very well and only took about 15 minutes. Has anyone took
through th complete run using the Next button and the crosshair method
to make adjustments in the alignment (you have to have used PAM this
way to know what I am talking about)drift
I still want to try the Pempro 2.0 alignemnt feature. It seems
alignment is better over all and can be done using only one star. I
have started drift alignment 15 minutes after sunset
