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.

I don't think that's quite right. I think you have the option to purchase
the extra double stacking filter for the PST to make it that way in which
case you are spending the
same as if you just bought a 40 or 60mm solarmax!

Now that you mention it, this is indeed what I had read and later
confused (over time) ... thanks for the reminder.
