MAS August Monthly Meeting

Jeffrey E. Shokler, August 2019 MAS monthly meeting speaker


Chasing Shadows: Planning for and Imaging ISS Transits of the Sun and Moon – Jeffrey E. Shokler

How do you catch something travelling at 17,500 mph as it moves between you and a target that might be 92 million miles away (or maybe only 240,000 miles away)? Longtime MAS member and astrophotographer Jeffrey Shokler will show us how to plan for International Space Station transits of the Sun and Moon, and also about his recent experiences capturing images of those events. You’ll learn about on-line planning tools, strategies for the week before, day before, and day of in terms of positioning and set-up. Jeff will also share the approaches he has taken to both capturing and processing the transit data in order to create finished images of ISS transits.

The Trifid presents the unusual combination of an emission nebula, a reflection nebula, and a dark nebula all in one object! The Trifid lies 5,200 light years from us in the constellation Sagittarius.

Messier 21 (M21; NGC 6531) is the beautiful, small open cluster containing 57 stars that is visible to the upper left of the Trifid. M21 is 3,900 light years from us.
