Yup. Apodizing mask. He calls it "The 60's filter." He even has an article on it on the CSAS website.

Which park was the event at, by the way? Chances are I looked through that same scope that same night.



It was at Fox Run Park




Ah, the infamous "night of the sprinklers" when Jason won the first awarded CSAS medal of valor for diving on a live sprinklerhead in order to save everybody's equipment.

Good times.

The amateur astronomer's equivalent of diving on a hand grenade.

Thank you, Markus. It seems to me there is still a lot of work to be done in figuring out the optimal method of apodization for Newtonians. It's certainly not all about the spider spikes!
