With SkySafari make sure time, date is set correctly of course BUT each time you use it check on the upper screen to see what it shows as current time/date. If you saved a setup and call it up, it may

Good point! I read "worm," I think of the worm, not the "worm wheel."

SharpCap requires a view of the pole. That is not always possible. In my case it is not. Tom

I use Sharpcap Pro on my 1200. Seems to provide a very accurate polar alignment and is very easy to use.

Joe, PEMPro does not directly start APCC. However, PEMPro launches the AP V2 driver, which may start APCC if the driver is configured to do so. If you are running APCC Pro, you should make sure to

Actually the heat wafting is happening in the baffle tube due to heat in the primary mirror. It can be quite bad. Happens in large SCTs also (C11, C14). Rolando

Hi Rolando For the east or western horizon for altitude alignment, I assume that you mean that the location where scope should be pointing should be close to the equator (point A) and not just

Hi Joe, I have an 18" truss tube with cooling fans, so I can say that you can have tube currents even with a truss tube. I found that heat can waft off of the primary, secondary, and even the ground

Hi Ray, Just curious about this. While doing my polar alignment runs the other night, I shut down any apps that might have been running, including APCC. The idea was to eliminate any other app

Hi Ray, Not worried by “tube currents” – it is a 14.5” truss rather than a solid tube. A little reluctant to experiment with greatly offsetting the polar axis, after spending around 6

Hi Eric, Thanks for the great feedback! I am glad you are happy with the results using PEMPro! -Ray Gralak Author of PEMPro Author of APCC (Astro-Physics Command Center):

Hi Joe, Even if PEMPro happened to chose Saturn or Jupiter, I do not think they are moving fast enough in declination to matter. -Ray Gralak Author of PEMPro Author of APCC (Astro-Physics Command

Hi Joe, If you want to confirm your findings, and that you aren't getting fooled by something else like tube currents, try purposely offsetting the polar alignment by a large amount in both Alt and

Happened to me to a few times in my first couple of months with the mount. Make sure you learn how to setup find home within APCC and know how to use it. Terri

Last night our transparency conditions were not the greatest, but seeing was good so I though I'd do a PEMPro for my 2017 Mach1GTO. Initially I was a bit let-down after seeing the +/- 4.7 arc/sec of

The curve looks smooth to me. I'd think it would show some irregularities if the worm were damaged. But you looked at my logs. What do you think?

Totally agree with you Ray. I like to do as you suggest, stick to rotation reference rather than east/west positional. Perhaps a good analogy is thinking how to steer an outboard motor boat.

Ray, One thought came to me during my problematic runs – the major planets (Jupiter & Saturn) are very close to the meridian right now, slightly south of the equatorial. This won’t matter

Yes Ray. We’re on the same page, and I’ve got my bearings. It is a standard “Push-Pull” system. Screwing-in the right side knob (on the west side on an AP-1200), where the AZ
