I was a bit apprehensive with this being a single-speed, having gotten used to their 10:1 two-speed models of late, my concern was unwarranted. While some of their astro-goodies were not too good a few years back, I haven't been disappointed with anything from them in recent memory. 36.37mm - and the tension-bolt gives me all-points from letting go will drop it like a rock, to it's needing a hammer to make it so much as twitch. But the travel of the draw-tube more than makes up for that - 47.98mm vs. This 1.25" Crayford is of a shorter profile than the old R & P. A trip to my local hardware-store will hopefully provide me with some black-anodyzed 16mm M4's. And it was indeed! No bolts for mounting are provided, though I suggested GSO should include these, and the bolts for the old one were too short for the thicker base, where they are recessed nicely - I had to scavange some nuts & bolts from my parts-drawer. As the listing on it from Agena had given me accurate dimensions on the mounting-base and it's pattern of drilled holes, my digital-caliper confirmed what should be a perfect fit. After figuring out the tension and release bolts, I dropped it into place where the old R & P one had lived for 14+ years. Flipped-open my Bali-Song and in a moment it was on my desk. Well-boxed (double-boxed, as Agena always is good about doing). So I listened to the lovely Sirens' song and 'pulled-the-trigger.'ģ-days later, it landed. While looking into Crayford-Focusers for my other telescopes (see signature), I saw a new entry on a listing out of AgenaAstro in California: A "GSO 1.25" Crayford Focuser (with 176mm base plate) for Reflectors - Single Speed." And went straight to the listing:Īnd at $85.00 US (£59.02), the price wasn't trying to murder me. And such was non-existant in my neck-o-the-Universe. One that didn't require major-surgery to the OTA itself. And I had looked high & low & sober for a likely replacement. But a Crayford-Focuser was always in the back of my mind and to-do listings. After I had taken it apart and greased it with some super-duper Teflon®-based bicycle-grease, it was certainly smooth enough to prevent any major impediments to using it. This was the focuser on it.Īs the scope was made before two-inch focusers were the normal standard, mine had a 1.25" R & P single-speed one. I had neglected to address the one issue that I had with my GSO 200mm F/4 Rich-Field Newtonian Reflector, which I bought in 2002 or 3.
