Hey everyone, just circling back to this post to share my results. After a couple of nights of testing, it appears like I have finally found settings that work well with my setup. I'm sharing a couple of screenshots of my settings below. What I believe is the main thing that I was seeing in lots of tutorials that was complicating things for me was the "western goto limit" setting. I'd seen in many posts and tutorials that this setting was counted backwards from the western limit of the mount, so in most cases it would lie somewhere between maybe 2 and 8-10 degrees. However, the losmandy gemini 1 manual states that this setting is counted from the CWD position, so it should be a value over 90 degrees (just past the meridian). I actually set it at 90 degrees because my western limit is very low due to being in the southern hemisphere and my RA motor is in the western side. So this setting I believe is that the mount will perform a flip when a go-to command is received at any position after 90 degrees from CWD (so right on the meridian). I also experienced the problem in NINA that NINA interprets the wrong side of pier (opposite of what it really is, which I suspect is another problem due to being located in the southern hemisphere). I tried disabling Gemini reporting the side of pier altogether but that brought on a different set of problems with PHD2 and guiding, so I reccomend leaving this setting on but disabling it only in NINA for flips.

In NINA, my "Minutes after meridian and "Max Minutes After Meridian" setting was actually determined using Edward's spreadsheet, which was very helpful to start narrowing down where possible problems could be. In any case, flips are very reliable now, the only problem is that my margins are really tight due to the physical configuration of my setup which allows for a very small range of motion past the meridian on the western side. Hopefully I can change this in the near future. For now, however, for my 2 or 3 minute long exposures, these settings work fine.

I'll also add that meridian flips also worked fine when using those low values for the "western goto limit" (I had 4.5 in there, see my previous messages with screengrabs) but this setting caused the mount to fail to go-to fairly large portions of the sky, particularly around the SCP. As soon as I changed the western goto limit to 90, the mount started slewing to every object I chose without restrictions.

Anyways, that's my experience setting up the G11 with Gemini 1 with NINA for fully automated go-tos and reliable meridian flips in the southern hemisphere.?
