BMAA Monthly Meeting
2026-06-03 19:30 - 21:00
BMAA is inviting you to a scheduled Monthly Meeting.
In addition to our regular agenda items there will be a Special Presentation on “Star Trackers” by John Urbanchuk

This presentation will cover the basics of using a star tracker with a DSLR or small telescope. Star trackers are relatively simple devices that allow the astrophotographer to take images that avoid star trails. Best suited for DSLRs and wide angle or telescopic lenses. I will describe what a star tracker is, what is best at doing, what to look for when buying one, how to estimate exposure time before stars begin to track, and polar alignment, I also will discuss several popular star trackers and their price, including the new smart telescopes and show some examples of the images I have taken with my trackers.

BMAA Monthly Meeting: "Electronically assisted observing" by Gary Sprague
2026-07-01 19:30 - 21:00
BMAA is inviting you to a scheduled Monthly Meeting.
In addition to our regular agenda items there will be a Special Presentation on “Electronically assisted observing” by Gary Sprague
This special presentation will describe approaches for using video cameras to augment visual observing. This is a “hybrid” approach to visual observing using elements of imaging with a video camera. It can be relatively easy and affordable (compared to standard astrophotography). Video cameras (camcorders, webcams, etc.) are numerous; they use CCD’s smaller than DSLR and can obtain multiple images/minute. Images can be viewed immediately using a video monitor or they can be output to a computer. The presentation will describe typical equipment available and demonstrate one particular approach.
