As a small suggestion, it would be useful to have a minimise button for the Automatic Observation Window, and to be able to re-focus in Automatic Observation Settings when temperature has changed, for example start focus if deltaT = 0.5 or 1 degree Celsius.

Have a nice day,

Thank you very much Cyril!

Yes, but I would like Prism to handle the temperature compensation, and I cannot enter a value bigger than 1000 steps.
The optec Leo focuser has 80 nanometers per step, resolution, so I need much bigger steps

Also, if I try to enter -1454 into Focuser 1, I get an error: the maximum value is -1000 steps/degree

Hello,
I have an Optec Leo focuser with an external temperature probe.
If I run the Optec wizard for determining the temperature coefficient, I get a value of -1454 steps/degree Celsius.
In Prism.v.11,focuser 1, do I input the -1454 or +1454 value?

Thank you, have a nice day

I tried your settings Marc . In order to compute the FWHM, I have to check the option "Seeing computation area defined as above"("Caculs de seeing Sur zone define ci dessus").
With that option checked everything works.
Thank you.

Thank you I will try with those settings. My original settings was with "whole image". I will try 1/2 central zone

Sure, here is a link to a couple of fits files:

Thank you very much.

Hello,
I am using the English version 11 of Prism.
When I select Analysis -> Quality check (stelar images), the resulting table does not compute the FWHM of my stars in a few images.
How do I set Prism to compute the FWHM of stars in the image?

Thank you.

Problem solved. I had to check the option "reverse guide mode when looking East (DEC)" in my mount software. Now I don't have to recalibrate the guider when passing the meridian
