While I was struggling with wide fields, I decided to return a bit to the Askar. What pleases me is the predictability of the instrument. Just press and it shoots. I decided to check out what this Cocoon is all about. There wasn't much time left, so I decided to take a series of 120-second frames to make it a bit easier for Cyril to stack the images.
