How to schedule an iTelescope for multiple objects?
Hi Greg,

I'm not sure if this question belongs here or in the iTelescope Forum, feel free to move it.

I'm trying to get up to speed on using the iTelescope system in preparation for an upcoming tutorial with Dr. Sasse next week. For starters I wanted to do astrometry on 2 main belt asteroids (10482) Dangrieser and (10483) Tomburns using iTelescope T05 in New Mexico. I created Imaging projects for each object as shown below:

When I ran the ST4i Scheduler, there was a gap between the observations of the 2 asteroids, so I decided to add some exposures of Comet 46P/Wirtanen to fill the gap. The Imaging Project for Wirtanen is shown below:

As the comet is very bright I tried to limit the exposures to 15 min/filter, but I messed up the exposure time for the blue filter and the Scheduler produced this Plan for T05: (Looks like I can't control where the attachment files appear in the post - this will probably get confusingĀ  Blush sorry.)

Question 1: Why did the Scheduler schedule Wirtanen 3 times? Given the brightness, 15 min/filter should have been plenty of exposure. 2 minutes should have provided SNR's in the hundreds for each color and 1000+ for the Clr filter. I didn't select the Astrometry option for the comet, but I did for each asteroid. This added 2 hrs to the plan's run time.

Question 2: If I strip out the extra Wirtanen imaging runs would the plan work properly or will the times for Tomburns be incorrect? Except for the extra Wirtanen images and the error I made on the blue filter this is close to what I wanted to accomplish.

When I tried to schedule Dangrieser only I got this plan: The dither command is included, but I don't see the explicit dithering commands for RA & Dec as in the plan for all 3 objects.

I fixed the error with the blue filter & got this plan as a result: Both asteroids are dithered, but there are still 3 series of exposures on Wirtanen.

It looks like I can't add more attachments. I add a second post with additional attachments after you have a chance to digest this one. Let me know if you have questions about what I'm trying to do. Maybe I'm asking too much of the Scheduler & should simplify what I'm doing.

Also, how do I remove an Imaging Project from the Scheduler's consideration? It now has 3 objects and I can't remove Wirtanen to schedule just the 2 asteroids. I must be missing something.
