My bad, i should not dash off answers while driving, they tend to be too short. if the Gemini saved index only when it was parked, we'd all be needing to re-do PEC constantly. If you lose power and

Anthony, Brian is correct. Gemini remembers the worm index position, even it loses power. PEC programming is not lost. You don't need to stop the motors or park the mount to preserve

Michael- I think if you return the mount to "Park at home", the motor stops turning. (At least I am pretty sure of this because I think I've noticed that I cannot hear it.) Theoretically, you could

Welllllll.... Here's the thing:. The PEC is a kind of reverse recording of the drive system. That is, the worm of course, but also things that move at exactly the worm rotation time and rate: I

Yes. The only way to mess up PEC is if you adjust the worms or other mechanical changes. wrote: Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

That should have read, "Will PEC be maintained correctly if...)

If I have PEC maintained correctly if I, (accidentally), shut down my G11G2 without parking at "home", manually return the mount to the "home" position, and did a "cold start"? I am thinking I might

I've actually been leaving my mount (The defunct AVX) set up, and when I mount my imaging rig as a unit to the mounts clamp, I can then check my PA through my Main telescope. But the tripod under it

Well Ross, I wasn't going to do all the legwork for you. LOL! If you scroll to the bottom of the link I provided, yup, there's the Eagle.

Yeah, I was thinking that too! Its the mount that must be made parallel to Earths axis, then everything else falls in line!

Nothing wrong with you... all GEM mounts have this polar scope shift issue. When you get your polar scope re-aligned, mark the rotation position of the polar scope in it's RA mounting tube, so you

Why would you remove it? Just get it centered and leave it in place. No polar scope will get you really polar aligned, just good enough to do visual reliably. Another thing to know is your initial

Sonny. Just my two cents here but i use my polemaster mounted to the front finder scope shoe on my takahashi e180 after everything is setup. Mi250 mount. All my astro is imaging and done portable at

Polemaster, or SharpCap, drift aligning — all of them just align the polar axis with the Earth’s axis. Specifically, they help adjust the mount so that the center of motion around the polar axis

Nels, sonny's right about removing and reinstalling your Polar scope. I followed Michael Herman's, technique in zeroing my polar scope then I do a drift alignment ( a pain in the you know what) that

*everything* Polar Aligned. it doesn't really work that way Sonny. you polar align just the mount. if you are looking for more accurate polar alignment, i'd suggest sharpcap. just as easy to use, no

Hi Nels, Any machinist will tell you that anytime a part is removed, it is a bugger to get it aligned again. So for accuracy, especially repeat accuracy, don't dismount it. I had a Polar Scope in my

My jury is still out about a Polemaster. It looks fine. But I'd want it mounted to my imaging rig and not the mount itself. That way, once it is true to my imaging rig, it could really get everything
