I would love to dig deeper into comets and asteroids with the hope of contributing to the MinorPlanetCenter (MPC). I realize that using astrometry packages is paramount to the process. The list seems dated:

Are there any other packages available and why no opensource options? I hate to be cheap, but it is really a bummer that I have cough up cash for science!

So do you need plate solving software?

Elbrus is free. Look for it in Yahoo Groups.

I'm not sure it's a need for plane solving. I seem to be able to find things ok with the GoTo and if need be a quick upload to astrometry.net or even astrobin.com. I think what's needed for MPC submissions are more exacting. They state that you need a software package that supports "least-squares plate-constants (LSPC) solution" I don't know if Elbrus supports this, but it seems that someone using it has an asteroid discovery!?

Thanks,

Mike

Also there is Iris, which I've used for DSLR and planetary processing, but not Astrometry...

I'm not sure it's a need for plane solving.



Plate solving for at least 3 known stars is the first step in determining the least-squares plate constants. Either Iris or Elbrus should work for you to do this. Once you have the solutions for 3 star positions, a simple excel program can do the least squares fitting to the plate constants.

Mike,

Try the freeware astrometry program: "Project CLEA Toolkit for Astrometry (Research Version)":

http://www3.gettysbu...ea/toolkit.html

I started out in astrometry using this program. It's more than capable of producing the accurate measurements needed for submission to the MPC.

Thanks all! The CLEA and Elbrus packages look good!

Wish me luck, I'm off hunting!

The packages Astrometrica (http://www.astrometrica.at/) and MPO Canopus (http://bdwpublishing.com/) are two good software packages,I use both.

Astrometrica would be a good long term investment for than $35 USA dollars.

Very easy to learn and used by many, excellant support.
