Wil & others concerned

I have been working with Marge & Roland on the sky interface just trouble
shooting for them. The pointng accuracy is just that 10 arc min from horizon
to horizon. The keypad has a refraction program built into it as well.

This is the best accuracy I have seen to date for a mount.  Plz keep in mind
Wil this is from Horizon to Horizon. 

The traking accuracy without any PEC is 2 arc seconds of error. As far as
I'm concerned thats excellent.

I'm processing a M16 CCD shot I'll post it soon.
