Autoguiding on an asteroids motion
So I want to take spectra of asteroids - but asteroids move. So I need to autoguide my scope - on a bright star - but have the guide star 'track' on the asteroids motion (make sense?)
The Asteroid itself will be too faint for my external guider/scope combination to directly guide on it.
Anyone know a piece of software that can do this? I know there are commands to send 'guiding signals to the scope to move it to match the asteroid but I'm looking for something that will do this same thing to the guide star tracking system.
My scope has to be guided at all times as it has 120 arcsec PE (yes a 14" LX200GPS Meade scope has this much bad tracking). I can get PE to fix it down to around 5 arcsec for a specific RA position but if I move the scope the PE shoots back up to 20 or 30 arcsec. Still not good enough to image without a guider.
Cheers
