I have been wavering about buying a PST in part due to discussions on this list
that indicate it is a very basic instrument that is not really acceptable unless one
double stacks the optics, at an additional cost of $800. Since the $500 for a PST IS a
major purchase, I keep wondering if I want to invest this kind of money in a scope that is
barely adequate. Am I the only one who feels this way?
[SIZE="Large"]YIKES!!! Barely adequate?!? No way José... er, David!!![/SIZE]You are getting a complete, sub-angstrom, solar H-a instrument that outperforms
anything anywhere near it $-wise on the market.
Some of the reasons many people are stacking them are because:
A) You
CAN stack 'em to increase performance levels even further.
B) Coronado designed the PST so as to make the procedure
simple and foolproof.
C) Solar H-a is
very, very addicting, and stacking may be a more economical approach
to placating the "fever" than moving to larger aperture systems.
Will you enjoy a PST sans-stacking?
You betcha', or I would not own one myself... even though I also have a 90/90/30.
My club purchased three PSTs, and they are constantly out on loan (and several members
have since purchased their own!)
What makes 'em so special is the design, craftsmanship and, lest I forget, the "magic"
that lives inside:
