focal length of the ASI290MM Mini

Hello,

I use for the guiding the ASI290MM Mini.

It is connected to the telescope via the ZWO OAG.

In the settings of the ASIAIR App I have to specify the focal length of the guiding camera.

Can someone tell me which value in millimeters I have to enter for the focal length of the ASI290MM Mini?

Thank you

Gregor

Hi Gregor

when connected with OAG, the guide scope focal length is same to the main scope's

Hello Jiang,

Ahh, okay!

That's logical, it's the same tube.

Thank you so much.
