... IHOP 2, although it might be 60 miles. Take Hwy 50 eastbound a little over 20 miles past Placerville. Just before Hwy 50 begins the windy two lane section...

next winter im having the mirror refiged to make it real nice. looking for 20 wave or better then servo cat has a kit for them now for 1245 Fred ... From: Jane...
... Are you going to have the mirror tested first? There was a pretty interesting visual test done several years back, between Peter Ceravolo and Terrance...
Hi Fred, When you get your mirror refigured...don't forget the secondary mirror. Also change the spider to a beefier one, such as the AstroSystems or...
... Doesn't it seem the 4 vane spider would cause more obstruction than a 3-vane spider. I wonder if anyone has done any testing to compare throughput on ...

I was talking o cary at optical wave labs and the meades are over corrected. I will have it tested of course because when you go to refig a mirror you need to...
I was thing about that too. would like to get as much reflectivity out of the secondary as possible. The primary will run me 530 to be redone not bad for $1800...
... Anything related to visual observing is perfectly good to discuss, as you yourself well know, Jane. It's an interesting topic. I think if you can...
Fred, Reflectivity doesn't mane anything if the secondary is bad. Check the figure on the secondary. Some are bad. My first secondary for my 22" was...
Just picked up a Baader Hyperion click stop zoom lens (8-12-16-20-24mm) after reading favorable reviews but haven't had a chance to use it yet. Want to use...
