Re: PEMPro vs PHD2 #Guiding

Hi Curtis,

Here's what you wrote:

Last night I ran a PEMPro v.3 curve on my 2010-vintage Mach1GTO,
and PEMPro came up with p-to-p of 6-something, which is the best I've ever
measured with this mount. But about three hours later I ran another curve,
and it was over 10
Please include all logs, including debug logs, and PPC files from that night and that night only. You can use the PEMPro Log zipper to easily select the files.

Ray, I have lots of logs, going back to July. I eliminated all but the latest one. I put the old ones in an "old" folder.
I didn't throw them away. You want to see them all? A few are aborted runs -- I didn't like where it was going on,
so I killed it. I've been doing PEMPro runs almost every night, twice last night. I'll fiddle with the balance (which is
spot-on exact now) or gear mesh and try again. Last night I was getting 19+ p-to-p, but it was smooth, so I
loaded it to the mount. Probably unrelated, but just before I shut down and went to bed last night, I tried some 5
min test shots of NGC 7331, and I had fantastic guiding, even the tiniest stars were round.

Edited to add: It's often said that one definition of insanity is doing the same thing over and over but expecting a
different result. Guilty!
