THREE MUST HAVES
Presented by: Stan Rosenberg
This month’s program will be presented by long-time GAC member Stan Rosenberg.
Stan has been a avid solar viewer and astrophotographer for many years.
He’s going to share some of his knowledge with the rest of us.
My program will talk about three gadgets which can really enhance
your visual and photographic experience. First good light
pollution reduction filters.
Second the Polemaster for good polar
alignment and third a Bahtinov masks for perfect focus both
visually and photographically. I will also discuss the Bortle scale
and the sources of light pollution.
***As usual all GAC members are invited to gather at 6:00 for dinner
prior to the meeting for food and conversation. Just remember that we
will now be meeting at the K & W Cafeteria at Friendly shopping center.
