Default ASTRO: Obsession 20 - Is it dark yet?

Hmmmmm........ Nagler 26mm in the FeatherTouch focuser, dew heater on,
digital read-outs on, full moon coming up (Oh No! Not the Moon!!!)......

Since I took this image I've replaced the dew heater unit with a better
system that adds pulsed heat to the eyepiece (or bino-viewer), and the
TelRad, as well as the secondary mirror. Dew?? OK..... I mean frost......


Sometime in the next year I hope to add a StellarCat GoTo system to this
scope.

Yes, I do have the Tel-Rad on backwards......... what do you expect from a
guy using a 20-inch Dob to look at the full moon!

George, with the 20 incher you could even do visual Halpha observations of
the moon :-)

Looking at the full moon with a 20" F/5, a 40mm eyepiece, and no filter will
nearly blind you. I'll project a nice image onto a white card.

At Hyde one day, we have stairs for little kids but a dad insisted on
holding the kid who was old enough to climb the ladder for a look at the
moon. He held the kid to the eyepiece so there was a perfect half moon
right between the kids eyes. He so held the kid there was no way she
could move her head to see the image. I tried to get him to let her do
it on her own. But he asked her; "Do you see it?" She said she did so
he asked "What do you see?" Her holder brother had looked at it and
said "Look at all the holes". So she said "I see holes." Dad was
happy, kid unhappy. They came back next month but the girl wouldn't
even try to look through a scope after that experience. No way you
could get through to dad.

I often used that moon image to help move a kid to the exit pupil but no
way I could with dad holding her in a vise grip like that. She probably
still hates astronomy as an adult as this happened over 20 years ago.
