The Tak bug has bitten again. I've just received a mid-80's (I believe) MT-160 newtonian from Lars Hansen. I think that this one has been through at least a couple of people here on IIS before making it into my care.
It's the older type with the single clamshell and Tak green in colour with grey fittings rather than the Tak white with green fittings of the newer examples. For its age, it's in good condition, with the mirror being cleaner than many new scopes I've seen lately. Native focuser size is 1.25", but I'm trying to figure out a way to fit a 2" adapter so that I can use my AstroSystems barlowed laser collimator. Looks like it's in pretty good collimation at the moment so maybe I'll get the old Cheshire out if I can find it. The focuser incorporates a Tak-typical rotating camera angle adjuster as standard. Beautiful!
This line of telescopes (MT-130, 160 & 200) aren't made any more, and are reputed to have been some of the best examples of newtonian optics ever produced. They are meant to give many top-end APOs a run for their money both visually and photographically.
I plan to run this one side-by-side with my FS-102 on the G11 with the FS60-C guiding for both. I'll run the SBIG on one, and the DSLR on the other - swapping from time to time. Should be great fun.
Thanks Lars - I appreciate you letting this one go.
