Re: Astroart 7.0 SP2

Ha Fabio, this was the only FFAF I did.
I have checked the FWHM of stars afterwards, and they were as small as when I did manual focus. So I guess, thatI was lucky. I can detect ca +/- 5 steps when focusing with a bahtinov mask, so I will reduce the step size next time.

Re: Applying dark results in dark image

Hi again - sorry for the inconvenience, I think I found out my self. I had a look in the AA7 help, there's a section called "Calibration".

Re: Astroart 7.0 SP2

Yes, thanks Fabio - I have just installed SP2. And tonight there will be clear skies, for the first time in more than a month (this fall has been extremely misserable in Denmark)
I am looking forward to try the full frame focus feature.

Save "Points" used for gradient removal

I have some challenges with my DIY flats box, so I am now relying on AstroArt's excelent gradient removal tools.
