The scope thinks it's the southern hemisphere as shown in this pic, where it? should be sayings it's in the blue zone. By rotating the Dec access pointing to the north it will again show its correct

Yes, that's right. Yes now using the hand controller. So the mount does this if tracking, but you can also slew Ra to the boundary transition point with the? hand controller. Driver display shows the

Paul, With the scope at the eastern limit of 90 degrees, the Az value reads 346 degrees. Slewing past the boundary value of 353 degrees? the value suddenly jumps to something in the 200s. Peter

So when crossing over 353 deg in Az, RA jumps by 7 hours? Is? that while tracking or when doing a goto? Did you confirm if that happens on the physical hand controller as well as in the driver

The jump occurs when you cross over the 353 degree boundary in Az.

I'm not thinking about the flip failing, but the RA coordinate jumping from 2h to 15h after a small move. Flips are performed by Gemini. ASCOM Driver just sends the command to perform one.

I have no model. I always cold start Gemini.? This problem has existed for months with many restarts/resets. During galaxy seasons target always ended up in this part of the sky, this is when I

Try to clear out and reset any model that you may have in Gemini, cold start, or even fully reset Gemini to make sure. Regards, -Paul

I realize the Ra is changing with the the earths rotation. I noticed a jump in the Az value also at thi stransition point? ?(Dec 15h: Az 353 degrees) to (Dec 2h Az 227 degrees) Az summing to 680

Paul, I've found a boundary condition were my meridian flip fails. The scope stays on the west side and ends up pointing at the ground. Any thoughts by folks in the group would be appreciated. I do

Vishel, It would help if you could post a few pictures of your mount (Dec and Ra worm drives. I ran an FFT on the raw data and you do have some nasty issues. There is a lot in this form on the 76s

A few points I'd like to add: I think everybody should check the relative position of the worm with respect to the center of the ring gear as the starting point when looking at Dec backlash. This is

Hi Bill, I'd get as close as I can to that intersection point. The question is ...where is it best? If you think about possible errors in polar alignment effects: when you are on the meridian, only

Hi Bill That should be fine - i would try to get close to DEC 0 as long as you aren't low in the sky the recommendation is generally two parts: 1. aiming close to that intersection is where star

I received a new G11G about 3 weeks ago. ?I’ve only had a few clear nights since receiving it so I haven’t done any guide calibration yet, I’ve just used it as it came and it’s done pretty

The method Peter used is exactly what I did, and also observed the ring gear being high relative to the worm.? Unless the needle bearing needs to be replaced for other reasons, a much cheaper/easier

Hi all, There is a lot to talk about here, to resolve several "impossible" puzzles, so please bear with me. The unsolved puzzles are: 1. Many people note that their worm gear spacing is very sensitive

baseline guiding to adjust? I recommend doing the baseline first, so we can better see the raw mount performance. Yes that is a newer mount, but I don't know what adjustments if any the seller may

Jeff, I just spoke with Michael Herman, as I was not so familiar with style of G11. I am defiantly interested.. Think yahoo and you have my email address. Peter

Brian, I was able to confirm with the seller that the mount was brand new and unused and if im correct in that the first two digits of the serial number (219554) signify the year of manufacture, then
