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. George N |

George, with the 20 incher you could even do visual Halpha observations of
the moon :-) "George Normandin" schrieb im Newsbeitrag ... "George Normandin" wrote ... Hmmmmm........

I'll project a nice image onto a white card. George N 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. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.
