the PST is the most basic of Coronado's offerings and this result is
outstanding for the "bottom of the h-alpha product line".

Bill,

There are thousands of PSTs out there but very few of them produce
images like that.
Perhaps most of the credit should go to the imager and the way he has
mastered the combination of the 'scope, the camera and the software.

There is no question that the imager and the processing thereafter play
a significant role in producing a great image. However, at the same
time, one cannot produce a great image if the optics do not allow for a
great image from the start. I paid approximately $1500/inch of aperture
for my AP160 and I can assure you that great equipment is the first step
to producing great images.

Hopefully Pete's unit is representative and not a hand-picked premium
sample unit.

Anthony.
