My Telescope Sings to Me

OK, I did not expect this.

I have been observing from my driveway each evening this last week now that the Moon has left the evening sky. Pleasant sessions wandering through the stars and clusters of Scorpius, Sagittarius, and Ara.

The week has also featured gentle trade winds at the house, resulting in fickle breezes around the telescope which is mostly in the shelter of the house. I get some manini gusts that make it around the garage that really do not bother me but do keep the mosquitoes down.

These breeze have created an unexpected phenomena, they make my telescope sing to me.

It is a gentle and resonant low B note as the breeze plays past the front of the telescope. Much like blowing across the top of a beer bottle, the tube of the telescope resonates with the breeze. Apparently a Cave Astrola 8″ f/6 telescope is a tenor.

Sometimes quiet, sometimes quite notable, I listen to the telescope hum while I look up the next cluster to observe.

Now if you excuse me I need to chase the pigs out of the yard… Again.
