It looks like the distortions from F5 and from F7 are too different, even for that option. May you post the two separate images?
Fabio.

I posted the separate stacked images here:

Two 10in SCTs F5 and F7!

This image is a stack of 10 x 1200sec subs at F7 and 14 x 900sec subs at F5. I used the 'Distorsions between images' option. No flats or dark frames (how?) Both OTAs were using an Orion SSpro camera:

This image stack was taken at the same time as the first image. Another NGC 891 with an Orion SSpro APSC OSC (6mp 7.8m pixels) CCD camera through a 10in F10 OTA ,on a CEM120, using a Starizona .63x SCT reducer for F7 (~1750mm); guided off axis. I used a 2X drizzle stack, 20 x LR deconvolution and DD...

NGC891 with an Orion SSpro APSC OSC (6MP, 7.8 micron pixels) camera through a 10in F6.3 OTA on a CEM60 using a Starizona .75x SCT reducer for F5 (~1250mm); 14 x 15min subs. I used a 2X drizzle stack, 15 iterations of LR deconvolution and a DDP pass. Acquired, OA guided, temp based focused, preproces...

It looks like that the StarShoot ASCOM driver is 32 bit only. with an internet search: starshoot ascom 64 bit it's possible to find the same issue on other software, for example: https://aptforum.com/phpbb/viewtopic.php?t=2395 At the Orion web site the latest ASCOM driver is version "100209", maybe...

I was able to get my CEM120 back in operation after being away for 6 months. I did 6 x 10min light frames and a whole set of darks and bias frames, all using AA8 SP3/64bit an a miniPC being run remotely via Chrome Remote Desktop. There was no really compelling reason to use the 64bit executable over...

Hi Fabio First off, I'd just like to say that AstroArt is an amazing piece of software and just gets better with every SP release. I have a query on the automatic reference stars Star Atlas option. There is a box titled "Astrometry". Could you advise what that is for and when should it be used. Reg...

Hi, I didn't understand "broke access", may you explain? what happened exactly? 32 bit or 64 bit? By the way it's possible that the first time v2.70 is used it's required to select again the camera from the ASCOM Chooser. The previous version is still available, you may switch between them without ...

Thank you for the report! Clear skies, Fabio. I installed AA Ascom V2.7 after AA SP3 and that seems to have broken the 64bit and 32 bit ASCOM camera connections. I uninstalled AA8, reinstalled it, reinstalled SP3 and I now have successful AA8 SP3 64 bit camera control on two separate installs. I wa...

I have demonstrated AA8 SP3 64bit Camera control using ASCOM:

Orion SSPro camera
ASI 178MM guider camera
CEM120 mount control
Rigel Nfocus temperature compensation focus control.

I recently drizzle stacked 17 x 15min subs using an Orion SS Pro camera with AA8 SP2 and the resulting image was excellent.
