Hi Thomas<br />sure I was thinking about your second suggest cause I&#39;m interested not oly to track stars. Now I will try write something that will permitt me to do this. I hope You will be here for some help....<br />Cordially<br />Marc

Hi Marc<br />Well, if you can calibrate the orientation of the telescope, then (in theory) you could calculate the required movement to follow a star based on current time, location, and telescope view direction. It might be a bit of a stretch for an Arduino to do all that sine and cosine stuff, but if you are happy with a straight line movement, then it would have to calculate it only once.<br /

Hi Thomas<br />excuse me for the delay but i was away for job..<br />No I would like to track only for visual. This will help me also to track clouds for time lapse photos.<br />Yes I&#39;m able to calibrate telescope I also are able to make telescopes!!<br />Cordially<br />Marc

Hi Marc,<br />With your Alt-Azimuth mount, do you intend to track for the purpose of taking photos, or just for visual observation? If photos, how long is your longest expected exposure (single image, not stacking)? <br />Are you able to calibrate the orientation of the telescope?<br /><br />Thomas

Hi my idea is to permit to regulate indipendently the speed of the two motor by two pot so that you can track for some minutes a star. Once you find the right speed the telescope would track for more time... I will now try to have a google account so no more anonymus!!<br />Cordially<br />Marc

Hi Igor<br /><br />I can try to help. Have you tried the Fancy Stepper Timer ? How far did you get with your setup ?<br /><br />email: Thomas at cncorbust.com

Hallo Thomas,<br /><br />i just get the same schield and want to drive two stepper motors to controll my telescope.<br />Could you help me with it.<br />I am worried because of blocking when using both motors.<br /><br />Igor
