Re: Any Tips From Experienced Mach2 Users

Thanks Roland for the advice. All excellent points. Much appreciated. The through the mount cabling of the Mach2 will be a nice upgrade for me and will open the door to more automation in my

Re: Create a PEM curve with a camera?

Re: Create a PEM curve with a camera?

Should work fine, IIRC Ray has a special version of PHD just for PEMPro usage.

Re: Any Tips From Experienced Mach2 Users

Re: Create a PEM curve with a camera?

Hey David, I'm sure you're right to be wondering about the guide scope approach. Have you used this guide scope / main scope together before and confirmed there is no flexure? If you haven't I'd be

Re: Any Tips From Experienced Mach2 Users

Re: Any Tips From Experienced Mach2 Users

For first time operation of any mount setup, run the Guiding Assistant, get all the data, evaluate it, and set the mount up according to what is recommended by the Guiding assistant. Why futz around

Any Tips From Experienced Mach2 Users

Any operating tips from those of you who have been using your Mach2s for a while now? I know that I need to remember to remove the RAPAS before slewing the mount. Guiding with PHD2 seems to be no

Re: APCC Pro 1.8.1.1 update #APCC

Hi Ray, Do you mind posting here whenever there is an update of APCC? My APCC never informs me when there is an update. (FYI, PemPro, OTOH, always does) Thanks! cytan

Re: APCC Pro 1.8.1.1 update #APCC

Where do you find these versions - 1.8.0.9 and 1.8.0.11? Are they developer versions? All I can find is "APCC Pro - Public Release Version March 7, 2020 APCC Pro v1.8.0.5". EDIT: Never mind,

I believe I have a fix already, but I need some clear skies to test it. So, hopefully within a few days. -Ray Gralak Author of APCC (Astro-Physics Command Center):
