Re: Absolute Encoders and Running a Pointing Model


Thanks Bill

our plan is unguided imaging on the CDK17 down at el sauce, so i'm banking on ae/appc. we are aware that it may not work out, so guiding is our plan b

Yeah, guiding can make things better. In some cases, you cant guide (i.e. no good guide star available on the chip) and the APCC/APPM model with the encoders can save the project.

Like this one:

Shot completely unguided using APCC/APPM, 1100AE, on 10" iDK scope.

Abs encoders can't compensate for OTA flexure, mirror-flop, etc., however a good pointing model might help a bit with those.

In a nutshell...

Guiding is like bacon. It makes everything better.

just out of curiosity with encoders, do you feel a need to guide?

Thanks Christopher. I just installed them and they show a nice improvement in PHD2 :)
