May 4: Let’s prepare for the coming Mercury Transit.

The Mercury transit is coming on May 9 so we will have a discussion about these transits.  We will also have a workshop to construct a Baader Film Solar Filter during the meeting.  This is one of the safe methods for viewing the Sun through your telescope. If you are making a filter with us, please bring your Optical Tube Assembly (OTA). We will also have time to share recent astrophotographs from some of our members.

The public is welcome to this and all monthly BMAA meetings; you don’t need to be a member to attend. The meeting starts at 7:30 PM at Upper Dublin Lutheran Church, 411 Susquehanna Road, Ambler, PA 19002 (About ¼ mile from the Butler pike exit of the 309 Expressway). Look for the yellow and black BMAA signs.
