Just a heads-up.

 

Vixen Optics has an 81s listed on Ebay.

 

Here's mine on an Orion goto and Berelebach tripod.

Love mine.  If the price is good, it will get bought quickly.

About the only thing that might make you consider selling it is a small cff, Stowaway, or tak.

You’re really making me consider it, even though it’s totally outside of my current plans.

Looks pretty banged up. Gotta wonder if it was dropped a time or two. Certainly doesn't look like it was owned by someone who handled it gingerly.

 

Even so, I would've been tempted to try my luck with a low bid had I not just purchased a C80ED with a Moonlite.

Looks like it fell down a flight of stairs.  Do all the 81s' have those annoying spacers in the light path?  I thought that was a cheap Chinese achromat thing.

It's an air-spaced thing...

Take a look at a Tak lens sometime....

I have and don't recall seeing them proud of a spacer or retaining ring.  Gross.

I believe there is a retaining ring which blocks (stops down)the aperture so spacers arent obstructing as much as they look.

That scope is a bargain.

Not me. I really thought about it, but I couldn’t figure out how I would explain it to my husband (because I am in the middle of negotiating other purchases). Seems like someone got a great deal.

I just said that so no one else would buy it.  JK, i swear it looked like a clamshell fracture in that one view.  It was abused. As everyone likes to say, you get what you paid for.

Hopefully the US Vixen dealer isn't selling a **** to someone. I'd bet 5 minutes spent on front element and dew shield scratches would have a positive improvement.

Bad angles and flashes could be the reason it looks so bad. (Foil spacers excluded, but I'm visual so that doesn't matter too much) My 90 fluorite with a bad angle and flash would look very much like Courtney Love.👍

We just had one donated to the public program at Lowell Observatory last month. It replaced our old Orion achro on a Twilight II. First night out last full moon, we deployed it for Moon rise. Comments from employees and guests alike were more than positive. Clean, sharp and virtually color free view (you really, really had to look for it). It's a winner in my book.

It seems to be a Japanese thing. My Vixen 103 has them, the Tak FS 102 has them and most classic made in Japan long focal length achromats have them. I've never seen any diffraction effects caused by them. Foil spacers would certainly be the last thing I would reject a telescope with optics as good as the Japan made Vixen ED/SD series

My post was just a sarcastic, tongue in cheek response to an earlier post referring to the visible spacers as being gross and annoying. Just about all my refractors, including my American-made Tinsley have visible spacers. Same for my yet to be mounted Jaegers 6 inch F/10.

 

They are often a sign of high quality, air-spaced optics, as opposed to the sometimes cheaper cemented lenses or lenses using plastic spacers.

Whoever got this scope got a hell of a deal.  I would consider one again for grab and go as it was superb optically, very light and manageable.

I knew you were kidding. My post was an all kidding aside to your post.

Here is a Vixen ED81s at the total solar eclipse in TN two years ago.  That's my kid.  Note that this is a properly mounted 81mm.  It is a Quark Combo h-alpha set up hence the power supply running to the etalon.
