Yes, using a script:
Image.Points.Count
returns how many points are selected.
and:
x,y = Image.Points.Get(i)
returns the coordinates of the #i point.
See in the Guide: Scripts / Function(Images) , "Points and Rectangles" near the end of the page.

Re: Preprocess Normalization
Hi, when the Sigma coefficient goes up and up, the Sigma algorithm becomes a classical Average/Add (without Sigma), which gives the best SNR. Sigma is useful to remove hot pixels and satellite stripes, but if these are not present, then Average/Add is better (also Sigma cannot be used for precise as...

Re: Suggestions for next SP
Thanks, may you send me or post a sample image?
Actually it would be possible to deconvolve differently all parts of the image, for example if coma is present. Every corner of the image will be different.

Re: Question: teleskope control settings ST4/Guide
Hello, if the autoguide window is not opened, then no autoguide pulses are sent, so it doesn't matter which "guide protocol" is selected. If the problem really happens when the telescope is connected (just for GOTOs), then try with a planetarium software. If it happens again, it's possible that the ...

Re: Start script from external program
Hello, maybe the problem is that: text = "None" may be 16 bit Unicode, while a 8 bit ASCII string is expected. If this is the problem, here are a couple of solutions: text = "None" my_dll.AASendCommand(VAL, text.encode("ascii")) or just for tests: text = b"None" my_dll.AASendCommand(VAL, text) see: ...
