Re: Needle bearings and axial play, is this a significant performance problem and how difficult is it to fix?
I thought the slew rate was limited by how fast the controller can count pulses?

Re: Meridian Flips and NINA
Brian, I think you must have it now as I just got an email. The test you did does not match mine. You need to slew on the other side of the meridian. Look at the coordinates in my video and you will

Brian, As I said this same thing happens using the hand controller. The scope is is this position per the image for this area of the sky in the video. It's not easy to make a video out in a field, in

Re: Meridian Flips and NINA
Hi Peter i was hoping to see this demonstration on the hand controller - I'm still not clear if you see this on the gemini by itself without hooking up an external application. [email protected]>

Re: Meridian Flips and NINA
I reset Gemini and reloaded everything. Slewed to that area of the sky and same problem, This? nothing to do with flips or NINA, but clearly there is a serious bug with the Gemini II software itself.

Re: Meridian Flips and NINA
You said the RA coordinate jumps on the Gemini physical hand controller, so no, this has nothing to do with the driver. Again, I don't know anything about NINA meridian flips, and can't help you

Re: Meridian Flips and NINA

Re: Meridian Flips and NINA
Can't imagine how the driver can do this, especially since the Gemini HC is also showing the same coordinates. The driver displays what Gemini reports.

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
