The 10" mirror has a focal length of 60.5", is full-thickness (1.6") and started out life as an ATM mirror; previous owner then had it refigured by Galaxy Optics (sorry, don't have the resulting specs). I believe the matching 1.8" E&W secondary is quartz, but can't swear to it. This combination renders the best images of Jupiter that I've seen, including festoons, detail into the polar regions, etc. Coating on primary is in good but not perfect condition, several small marks (about 1mm by 2mm) left by mirror clips. Primary mirror priced at $375, secondary and 4-vane spider at $60, prefer to sell both together for $420, shipping included. Selling only because I have very reluctantly concluded that a 10" F/6 is just a little larger than I can easily manage (no permanent outside storage available, unfortunately).
Televue Equalizer also available, less than a year old. Priced at $45, including shipping.--SALE PENDING
While I'm at it, I've also got a converted microscope head binoviewer. Collimation is good and Tiyoda optics are clear and sharp. Priced at $150, including shipping. Takes 1.25" eyepieces, but requires 2" focuser. Just haven't been using it that much lately.--SOLD!
Finally, I've also wound up with a large plastic lens cap for a Synta 150 refractor, priced at $5, including shipping.--SALE PENDING
Clear skies to you!
