A note from Wyatt about his 10" F4.5 telescope . . .

"Hi Dennis,

Just got back from a second weekend at the Texas Astronomical Society Dark Site in Oklahoma, so I have had my scope out now for about six long, dark nights with no moon to contend with. I’m getting everything dialed in – finder mounting, azimuth bolt tension, etc. The scope is just performing beautifully and is a real joy to use. I didn’t expect the portability to be such a big deal, but it makes transport and setup/breakdown very easy, which encourages me to get out to the dark site to observe. Very nice!

Thanks again! - Wyatt"
