Distance from mount to sensor AR7iv

[eric garen]

I want to connect my Alpha ar7iv to a telescope and in order to design the correct adapter I need to know the distance from the surface of the lens mount to the CCD sensor. Can anyone provide that information? Would really appreciate it!

This image (a composite on three different nights at different phases of the moon) was taken through a smaller scope where I can just connect using a 2" adapter tube, but for my larger scope I need an actual hard connection between the camera and telescope.

Thanks for your help!

On the top of the body, just left of the viewfinder, you will see the focal plane marked by a circle with a line through it. This will allow you to measure the distance to the surface of the lens mount.

Thank you! Just what I needed.
