Thanks Jasem. I'll try this but I have my suspicions now turned towards this.... See the attached screenshots, one is within the PA tool after it takes the 3rd rotation exposure (Polaris is exactly identified). The other one is a simple plate solved exposure taken at a different time. I don't remember if I had the mount in the same exactly position but the coordinates look close. In this one Polaris is NOT identified correctly, which is weird! Perhaps this doesn't affect the Alignment Tool but I'm not for certain!

So noisy! Why such short exposures?

A few nights ago I got to test my ASI120MM 'polemaster' with a 50mm lens mounted in the center of my HEQ5 Pro. It worked flawlessly, easily achieving a 1 minute error within minutes on the first iteration. Undoubtedly I could have gotten sub 1 minute with a second adjustment, not that it would be much benefit to be that precise on a temporary setup with autoguiding.

I know that this has been a while, but do you happen to have the STL file for this adapter that you could share? I'm looking for something exactly like this. Thanks!

The problem with the original design of the adapter is that it is held in by the rubber O-rings, not by a secure clamp. That probably makes it shift as the mount rotates. If a clamp solution can be incorporated into the design that prevents shifting as the mount turns, it will work fine.

Indeed. I did modify my design quite a bit after those earlier posts.

I started down this path recently and I'm now waiting for the lens to arrive to use with my mallincam GP. I started to try with the all-sky lens but since its a fish eye lens I assumed that would mess things up. Did you set up a "telescope" Ekos that had the specs of your lens then use a separate profile with just the CCD that new scope to perform the PA routine?

I just had the required focal lengths saved as of the configured telescope info presets, then switched back.
