Wyatt and his 10" XT10 Conversion . . .

Wyatt, from Dallas Texas sent along a photo or two of his XT10 DobSTUFF conversion. Here's what he has to say about his telescope:

"Hi Dennis,

Here is my DobStuff XT10 conversion out on my driveway in Dallas for some observation of Jupiter on Saturday morning, December 19. Just average seeing, but I still managed to watch a good part of an Io transit over about an hour with some reasonably clear views throughout the session. The scope is really great to use. 
Back when you were doing the build for me, I mentioned that primary mirror cooling was one of my main reasons for doing this. I now run both the mirror cell fan and (don’t laugh…) a second cooling fan as shown in the picture. This homemade implementation – rubber bands and all — works really well. The cooling power is greatly increased and I don’t notice any vibration/image blurring. (I have tested it with the second fan both on and off on during planetary observation like the one from yesterday morning.) Anyway, FYI and thanks again for the great scope! -

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"
