Dear Jasem.
Thank you very much for you reply. 
Regarding effective focal length, I suppose you mean Primary Scope definition in the Connect screen, right? I have defined various presets also for the same lenses with different focal length. FI, for my Canon 70-200, I have 3 different definitions, 70mm, 135mm and 200mm.

For the focusing, do I need defined also Focuser (Focuser simulator) in my profile? Without it, Focus module is not accessible. Do I need also any additional settings for it? I understand, there is no live view, just short exposures and focus is based on taken images. Do I understand correctly?

Thank you.
