Description: Everything about this beautiful optical tube assembly (OTA), equatorial mount, and tripod set reflects high standards of artful design, superior materials, craftsmanship, and build quality rarely observed anymore. All components were entirely nihon sei (made in Japan); estimated date of manufacture, circa 1990. The set consists of the following components: Vixen A80M Achromatic RefractorOptical specs: objective diameter, 80 mm; focal length, 910 mm (f/11.4)Light-gathering power, 131X; resolving power, 1.45 arc sec OTA length, 36 in / 915 mm; weight, 5.5 lb / 2.49 kg 6 x 30 finder scope with crosshairs (front and rear caps included); can be rotated for left-tilt, straight up, or right-tilt configuration Vixen Super Polaris Equatorial Mount144-tooth worm and worm wheel gears for smooth, precise tracking; R.A. and Decl axis graduated setting circles Designed to switch easily from traditional German equatorial mount operation to alt/az mode with free slewing when RA/Decl clamps are unlocked and slow motion control when clamps are locked (see photos) Load capacity stated by manufacturer: 7 kg / 15.4 lb (NRO could not determine if that includes the 2.8 kg counterweight) Installed polar alignment scope (please note: Although the etched reticle is expired, polar alignment adequate for visual use only can be achieved; highly precise polar alignment will likely require separate purchase of an updated polar scope or alignment by other methods); polar axis illuminator pen and front and rear polar axis caps are included Vixen AL-150 Aluminum Tripod Legs measure about 32.5" / 82.5 cm when retracted and about 59" / 150 cm when fully extended Tripod platform was specifically designed to accept SP mountsViewing and other accessoriesOriginal Vixen 90-degree zenith prism diagonal 3 eyepieces originally sold with this set: Kellner 20mm, H.M. 12.5mm, and Or 6mm (all in 0.965" format) Original front and rear caps for 80M objective and finder scope, Allen wrench set, and screw-on metal pegs for tripod feet Original lidded green plastic accessory box, with plastic wingnut bolt for attachment to tripod leg spreader Never-used metal sun viewing board with metal arm for attachment to scope focuser**Important notes: The telescope can be easily converted for use with 1.25" accessories with separate purchase of a 36.4mm x 31.7mm (1.25") adapter (Vixen part no. 3720) or a hybrid 0.965" x 1.25" diagonal (the latter method is often recommended for maximum FOV). The Super Polaris mount is readily upgradable to motorized RA-only tracking, RA+DECL tracking, or full go-to capabilities with separate purchase of pulse/stepper motors and a suitable controller available in the resale market or from a variety of manufacturers (eg, AstroGadget released an upgrade kit specifically designed for the Vixen SP mount in early 2024!). None of the optional items mentioned in these notes are included in this listing.** Message NRO and we'll send a PDF of the English-language version of the complete Vixen instruction manual for the SP mount, which details proper setup and use of this equipment and contains a wealth of other useful information. Everything depicted in photos will be packed in the original highly protective packing materials and shipped in original Vixen factory box. **Signature required on delivery.** Thanks for visiting Nippon Rare Optics!Premium optics sourced from Japan ▪ Fast, free shipping from U.S.-based seller
