Scarry? Why?

(1) 40 mm filter ... (2) $500 or less for 0.5-0.7 Angstrom bandpass ...
the PST is the most basic of Coronado's offerings and this result is
outstanding for the "bottom of the h-alpha product line".

I see it but I don't believe it! For one thing they don't say 0.5-0.7 band
pass. They do
say 1.0 A. Where do you get those values from for the PST?



It is my understanding that the original PST's were indeed 1.0 A
whereas the latter models are 0.5-0.7 A.
