I'm impressed - 135mm+ATiK16ic-S

Sometime ago I set up an old Zuiko 135mm f2.8 lens with the ATiK16ic-S as an electronic finder on the C11.

It gives almost a 2 degree field and is very handy when remotely controlling the scope to verify I'm actually looking at the star I think I am!!

Never really checked the limiting magnitude of the finder image until last night.....

With a 1 sec exposure (using Artemis Capture) 1 x 1 binning, I have measured star images below 12.4mag. This is from a site only 10Km from the centre of Brussels and plenty of light pollution around me.

I'm impressed!!
