Astroart 7.0 SP2
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.

Full frame focus works fine, thanks for a great new feature!!!
Here's a snap from last night, when I tried it out.

Re: Astroart 7.0 SP2
Great, I assume that this is the first exposure of the night (?)
If not, for autofocusing during the night, the Step must be lower, because the defocus must be much lower. I'd say maximum 50-100% of star size, for example, if the good focus for your system is stars of 4 pixels then the Step must be configured to have stars of 6-8 pixels at the extreme positions. This will allow shorther exposure times too.

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: Astroart 7.0 SP2
I tried Full Frame AF last night along with the Sequencer and it worked extremely well. I started the night by using the original single star AF using a large number of steps and multiple exposures to get a tight focus, and then FFAF between each integration, to keep focus tight throughout the night. I'll probably switch to using FFAF exclusively.fabdev wrote: ↑30 Nov 2019, 12:36Great, I assume that this is the first exposure of the night (?)
