Re: Charon

Hi All,

Another vote for : "Please do NOT discontinue support for Charon."

I have completely automated Charon for tracking and general plate solving. My own custom observatory control program shells to Charon using a keyboard buffer utility. It then exports the Charons result to file which is interrogated by my application and used for tracking. Its also used as part of an automated asteroid hunting system. The image is also presented in Guide - nice. This setup has been working great for about 2 years.

No other application is available that fits my requirements as well as Charon. Long Live Charon.

Cheers
Peter - MPC:E18
