As a result of last night (unsuccessful) observation of Procyon B with my C11, I was thinking about building of suitable "coronograph"...



Obviously, I will need to place it in the system focal plane, and I wil have to use relay lens to project the image of the blocked star and remained star field onto the image sensor.


The blocking shade should be suspended by thin wire and it should be quite small, 10-20 pixels maybe? That is ~100um, 0.1mm..

Quite a challenge....
