Re: R: [APML] Beep on ST4

Hi Massimo,
   If you have a full field image to post maybe the group can tell if its
field rotation or tracking errors
causing your star trails.
 What do you set your alarm cycle setting at ?
I set mine to 4 on hazy nights. I found the ST-4 will continue to track
unless it looses the star
for more than a few seconds.
Joe.
