Can anyone with a FS-78 tell me the distance from the rear of the dewshield threads (with dewshield removed) to the front of the objective cell?

Thanks!

This would vary a tiny bit with collimation adjustment..

I get 45mm from dew shield stop to front of objective cell. As Mike states, this may vary, albeit very little, with collimation. Dare I ask----no,I better not.
