Out of curiosity, will the SM-40 Double Stack screw onto the front of a PST?

[Hans Tucker]

Does the PST have an internal thread? It will need an adapter.

This is from the PST Instruction Manual:

"It is possible to attach anSM40/T-Max™ combination to your PST™ to further reduce the bandpass. In the majority of cases the SM40™ will "match" optically with the PST™ to provide views at ~<0.6Å. In a few situations you may need to return both PST™ & SM40™ to the manufacturer for "matching". There is a nominal charge for this service."

also:

"The PST™ has been developed with an internal version of our Sol Ranger™ sun-spotting device. Looking at the PST™ head on you will notice a small
opening on the face of the PST™. This is the light input for the Sol Ranger™ and must remain unobstructed. Adding a SM40/T-Max™ will obstruct the Sol Ranger™."

So yes it will attach to a PST. I have read reviews that state that the surface detail is greatly improved, but the view is much dimmer, and prominences are harder to see.
