This is the "Magellan" made-in-Japan 1.25", optically clean. Was used with a set screw so there may be a barrel mark. Original box and caps plus I'll throw in my field container for it, a Home Depot thingie that seals it up and works rather well. Sort of like a bolt container, but Home Depot's version.

Following extensive discussions on the ap-ug and sct-user yahoo groups, I can tell you that this and other wide field eyepieces work by shortening the off-axis focal length to less than the nominal focal length. (but it is 20mm on-axis, as are the all other widefields; Televue web site has some stuff on this too).

I think it is a good deal for the price asked and definitely preferable to the TV 32mm plossl new or used --you get about the same fov, and a darker sky background. It also delivers the same fov as a 24mm Panoptic, but is not as well corrected off axis.

So it is the rich man's Televue 32mm plossl.
And the poor man's 24mm Pan Optic.

Price includes USPS CONUSA shipping. MO preferred but checks OK from well-rated astromart users.

thanks for looking,
Greg
