And there I was thinking Well at least I'm not deep in the African bush like poor old PK.

Looks like you have a big backyard.

Prepare for me to set up camp there. It's just an easy 9 hr drive for me. You may want to put some more beer in the fridge....

:-)

One question, though: I don't think you are guiding through your main telescope at almost 2000 mm FL, are you? So I think the calculated RMS value is overly generous. You should substitute that with your guide scope in the drop down menu. That will probably bring your RMS into a more normal range.

I would also guide at 1x1 bin, not 4x4 bin for maximal resolution.

Looking forward to talking more about this around the campfire.

See you soon,

I do guide with an OAG at 1956mm focal length - f/7.
Note these are 10 second guide exposures, at the CEM120 EC2 tracks really well in between.

Got it!
But 0.15 RMS feels unreal. What RMS are you getting when you do not use 4x4 binning, but 1x1 binning?

There used to be a mistake in the algorithm in which the reported RMS was simply divided by the binning factor, without making any difference to the real RMS. Both Wouter and I were mislead by this for a good while, as we were using 2x2 binning which neatly cut the reported RMS almost in half while actually worsening the true RMS through reduced resolution of guide star movement.

I wonder whether that problem has been resolved or possibly crept back in again.

Could be, not really sure. But I don't have a tracking issue imaging at 1956mm focal length. Examples seen above.
I have not tried 1-1 yet. But since I see no tracking issues, I'm not sure I need to. I can see errors at 0.4" easily and right now I rarely get those anymore. I am keeping about 90% of my images.

Not sure if it makes a difference, but I am in central NM at 7,000 feet altitude.
