Objective lens wanted

[pmrid]

I recently bought a 90mm coated airspaced achromatic Obj with a 500mm FL from the Surplus Shed and it has arrived. It wasn't particularly cheap either. But it is a shocker - unusable except as a paperweight. But in the meanwhile I had constructed a fantastic little scope I had planned to use either as a guidescope or as a portable scope to take bush and to astrofests and the like for some DSO photos etc. SO now I have a great scope but no objective. Does anyone out there have an old scope in the garage with a usable objective of about the same size FL etc?

What about it makes it "unusable" Peter? I have the 80mm version from SS and it's a ripper. Are you sure that the cell components aren't loose - i.e. has anything rotated loose allowing the flint & crown relationship to change? Are you sure it's the right way around? When the 80 came out everyone complained that it was hopeless - but they'd mounted it the wrong way around because it looked more natural to have it round the wrong way. A note was issued by SS asking people to mount it the other way and suddenly everyone's objective did as advertised.

Here's a shot through mine:

Hi Chris and thanks for the note. It will be embarrassing as hell if that turns out to be the solution. I will go to the shed forthwith and reverse the lens.
I have seen some SS lenses with the comment that the front is not the way it looks at first, but not on this one. However. I'll report back and eat a suitable amount of crow if that is the answer.

Does anyone know any nice Crow recipes?

LOL! Nice to know that your money and time aren't necessarily wasted Peter. Good outcome.

I certainly hope so, as I would love to see the crow eating picture. LOL.

Sadly, the crow is a protected species so your wish will have to go unfulfilled.
