Software to find available objects in dome opening new
      #3425717 - 11/02/09 03:28 PM

My home observatory construction is well under way. I would like to do some semi-automated imaging. I need to be able to locate all objects currently visible in my dome- that is between certain alt and az range. Preferably sorted by major axis of the object so I can match objects to my cameras. To begin with, my dome won't have automated rotation, so I need to just stay in the current position, but then as objects appear in the slot, I can start imaging them while I'm snoring away in bed. I don't have a lot of money left to spend on this right now, so freeware or low-cost software would be preferred. I'm also fine with writing a software interface if needed.

Thanks!

Depending on what planetarium software you use, you could create several horizon templates that match your dome slot for the azimuth that it is pointed in. Then it would just be a matter of creating a list of whats visible for the time you want to image. Alternatively, and more simply, you could just point the slot in either the north or south direction and determine when an objects transits the meridian and image it then.

Thanks,

I'm leaning towards rolling my own solution. My South is a bit obstructed and my North has a truly amazingly bright streetlight. I'm getting close to having a VB program set that spits out available objects. Hopefully a couple more evenings of coding and I'll have it. Then I'll hook everything up through ASCOM.
