Progress with the New Countess

A windless, bright day meant I could take the Countess into the garden and learn more about how it performs.

Successful experiments with low light and hight contrast situations have been encouraging. Focal lengths from 4 to 10 inches were tried with F stops from F6.3 to F45.

Exposure times ranged from 2 to 10 seconds.

However focussing is still difficult – I was waiting for a replacement screen that arrived a day later.
Here are pictures to show the difference in screen thickness.
