"Rusted" PST 40 Solar Scope

[thunderchildobs]

The PST has what is known as a "Rusted" Lens. It is a fault that makes the objective lens look rusted. It seriously affects the quality of the image. The scope could be used as parts of a ATM project or could be upgraded to the following.

Ideal candidate for a 80mm PST mod??

[Poita]

That is my intention, there is a celestron 80 awaiting its new B-R-A-I-N-S!

[Merlin66]

If this isn't sold - I'll buy it!! - at your price!
Let us know what the status is????

[Poita]

It is already mine I'm afraid, I'll document the mod and post it up in the forums.

BTW, is it possible to stack using two PST etalons, or do you need a special type?

[Merlin66]

Yes, you can double stack PST etalons. You need a special adaptor (I have drawings) BUT I found it very very sensitive and almost unworkable.
Much easier to double stack with an external etalon like a SM60 etc.

I might give it a go just for the frustration, erm, fun of it.
