Lacerta offers a flatbox controller (FBC) to create flats for DSLR and CCD/CMOS cameras:
The controller has an USB port to connect to a PC. Some astrophoto software like APT supports this flatbox controller to create flats.
Here you can find a demonstration video and how comfortable it is integrated into APT (starting min. 7):
It would be great, if this feature would be add to ASIair pro as well...
I would like to place a feature request to implement such a Flat Wizard in ASIair pro software, as it is available in APT and N.I.N.A., and supporting Lacerta Flatbox Controller (FBC) hardware with ASIair pro.
