I originally bought this giant Dobsonian from Peter Kron (of Astronomics), who apparently made a number of excellent large Dobs back then. Over the years I've modified it and added a bunch of things to it. According to Peter, the mirror was probably made by Steve Dodds while at Intermountain Optics (I don't know Mr. Dodds, but understand it was "before Nova"). It is of excellent optical quality, and is complemented by the heavy-duty build quality of the supporting components. I especially like the truss-securing hardware, which makes take-down and assembly easy for portability, and the scope nests for transport. If you look at the pictures (which sometimes show different hobby configurations over the past 3 or 4 years) you'll see that the scope is outfitted with multiple finders, including a Celestron 9x80mm (in new rings), a 4" short-tube Sky-Watcher refractor, a Telrad, and an 8" Meade reflector (this rides in home-made PVC rings that slip into a DYI dovetail for easy removal). There's also a JMI 2" focuser, a fan (which I removed, but which can be reinstalled), some old 90s JMI encoders I never used but you are welcome to if you want them, as well as a slide-in plywood back door that protects the mirror, and, finally, wheels and wheel-barrowing handles, which I've used to roll the behemoth out of the "barn" and onto a concrete silo I had constructed at the farm (outside of Steelville, Missouri) for use as an observing pad.

Mechanically, the scope is a tank and in good structural condition, though with a lot of the age-marks and badges of the perpetual, do-it-yourself hobbyist, which is what I am, though at my age not so much anymore. It's not a brand-new-looking fashion-plate scope, but I think it's handsome. The mirror is gleaming. The wood has birthmarks and beauty marks: lots of puttied screw-holes from various counterweight placements, bracket-attachment locations, eyepiece-holders, star-map shelf-sites, and so on. These will testify that the telescope has been used lovingly, maybe even imaginatively, and been reinvented and tweaked endlessly. Optically, the 25" mirror's long f/5.5 focal length give it an edge in imaging quality, while the deep-sky performance has always been gorgeous, with less coma than in shorter focal length mirrors. The views through this scope still take my breath away, but I'm a retired University prof now and it's physically hard for me to use the scope as in my youth.

I live in Denver, but am located in Huzzah, Missouri (about 17 miles from Steelville, on the Huzzah Creek) and will remain until the first week of September, during which time the telescope will be available for pick-up. This telescope has been a source of pride and observing satisfaction for me, and has impressed members of the Denver Astronomical Society with its views, and has delighted many others, including family and friends and visitors to Colorado and Missouri.

Thanks very much for your interest.
