Hi Jimmy, You use Rolando’s “visual method” of polar alignment,which is excellent for a portable system, while in my fixed setup, Ialways use computerized CCD methods – PemPro Polar

Aligning for zero Dec drift goes back to the days of single axis drive mounts (mounts that had no Dec motors). With this alignment you could reduce or eliminate your Dec drift and concentrate on

Is it better to align for less dec drift or to align for pointing closer to the (refracted? actual?) pole? Dec drift can be easily guided out since it's smooth and always in the same direction, so it

Excellent! Who says you need a web cam and thousands of images to get a great lunar image? Jim ---- "Robert Chozick rchozick@... [ap-gto]" <ap-gto@...> wrote:

It's very simple, you have a 4 arc minute error in the altitude axis, otherwise known as polar misalignment. That is of course due to your drift alignment method which does not result in the polar

Shimming RA has no affect on Dec. Sounds like flexure, Dec backlash or polar alignment That's the way I polar align Dec. Center any star on meridian Recal Meridian Flip back to same star. Press North

If there is a DEC error when flipping the meridian, I would suspectmechanical flexure someplace in the optical axis. ChristopherErickson Consulting Engineer Summit Kinetics Waikoloa,

Hi, Just a follow up on the mostly successful shimmingprocess on my RCOS RC-14 truss. Originally, the star was completely offthe CCD frame after a meridian flip. I inserted a 1/4” wide x

I'll be there.

I'll be at ASAE, looking forward to seeing the great folks at AstroPhysics again!! At 04:23 PM 9/9/2014, you wrote: Those who say it can't be done should stay out of the way of those whoare doing it.

I'll be there too! ChristopherErickson Consulting Engineer Summit Kinetics Waikoloa, HI96738 www.summitkinetics.com

I haven't posted lately (probably 'cause I haven't had any problems with my AP1200 in years) but I'll be there for both SWAP and ASAE! I'll be sure and stop by. I don't know if you will remember,

That happened to me once. It turned out it was a setting in PHD. I had forgotten to put "on camera" as the mount setting.

Astro-Physics will be exhibiting once again at ASAE on November 1st and 2nd at the Exhibition Center in Tucson, AZ. This is an astronomy expo that you won’t want to miss. Please stop by and chat.
