Tested the mono camera with the original glass. Patrice, just as you said the star bloating is visible.

My cameras are not finished yet but I will use the Astronomik MC-clear glass at the front of the mono camera to seal it. MC-clear has excellent anti-reflection coatings. So, I will leave the sensor without a cover glass and try this first. It may be few more weeks before everything is ready though.

One issue I can foresee is that my colour camera will have 1mm thick glass in front of the sensor while my mono camera won't have it. So, the colour camera will have about 1/3 mm longer optical path to the sensor. This is very close to the tolerance of my flattener which is +/- 0.5mm.
Possible solutions are to remove the cover glass from the colour camera or to use anti-reflective MC-clear glass at the front of the sensor. Hmmm... will probably need to test it before making any decisions.
