Share Table

Prashant demonstrated the use of red lights to highlight the tripod and its legs during skywatches.  He also showed us some of his glow tape and glow sheets he has been looking for, and recently purchased.  This will also be used to mark the legs and footings of the tripods, to prevent accidental kicking of the scope.  The glow sheets had a glow life about the length of our meeting, even though they were ‘powered up’ by distant ceiling lighting, and not point blank lighting.

We got an email asking about how to build a “Barn-door tracker”.  To prove this is a valid item, John Barnett brought in a 30-year old “Barn-door tracker”.  After describing it as a “precision piece of work”, he showed us how it was manually adjusted to keep the scope aimed at the same location in the sky.  It had holes to handle sidereal rate and lunar rate.

Short Talk:

Astroimages Hot Off the Press!,  by Tim Streagle

Tim briefly explained his process of taking photos and processing them.  There was an earlier presentation months ago explaining imagery in details.  This presentation was to show his recent successes of the photos taken from the scout camp.   His photos were quite impressive and were images of the triplet in Leo, a couple of spiral galaxies, M51, M3, and ended his photos with Comet in Hercules from January.

 

Major Presentation:

Science on a Sphere, by Leslie Bochenski

Leslie took the group down to the first floor to show how science and its discoveries can be displayed on a 3-dimensional globe. 

The program we saw was the “observe & inference” SOL lesson for middle/high school students.  Actually, it was called “Globular Clusters”, demonstrating the outward motion of globular clusters while looking towards the center of the Milky Way.

Afterwards, she passed the controls around and let us display each of the planets and “spin” the planets to observe all views.  It can show physical occurrences on the Earth.  For example, we can see weather, climate changes, and where earthquakes and aftershocks have occurred at any time on the Earth.  We even pulled up the recent quake that occurred in Mineral,Virginia.  It was very spectacular when we took a look at the major quakes and hundreds of aftershocks inJapana few weeks ago.  It was quite a learning experience and can be very useful to teach to any group.  I notices how several of the members were examining how 2-dimensional views were displayed on a 3-dimensional object from 4 different directions.

The SMV pamphlet explains Science on a Sphere as “Animated images of atmospheric storms, climate change and ocean temperature are shown on the sphere, illuminating sometimes complex environmental processes in a captivating way”.
