Miss Manners will tell you that it is not polite to take a
Tagamet even in private before setting up a nightime photo session.

But a lot she knows! Focusing a medium format camera poses a unique
focusing challenge she will never understand. Since the film area is
so large, the film in the camera does not necessarily lie perfectly
flat across the entire film plane. Combine this with fast refractors
with non-optimal field curvature correctors and it's bloated image
ulcer time!

If you own a Pentax 6x7 or 645 medium format camera, the Series III
'Stiletto' is the astrofocuser for you. It attaches to your t-ring
or coma corrector adapter the same way your camera does now since the
Series III employs a factory-original Pentax bayonet mount. While
the Series III P models come pre-calibrated, the adjustable 'Stiletto'
helical focusing mechanism allows you to easily customize focusing
for your particular camera/telescope combination for optimal results.

The best news of all is that the Series III is totally flexible. With
a simple change of the modular mount, it can be used with just about
any 35mm or CCD astrocamera as well - with no recalibration in between!
Snap-in, variable-resolution ronchi gratings (and even a True-Knife
option) allow you optimize focusing given the limitations of your own
eyesight and the brightness of the object you are astrophotographing.
(Is that a real verb??)

So, visit our website today to read the rest of the techno-hype on
the Series III 'Stiletto'. At a minimum, bookmark us so you'll
remember us before taking the next Tagamet.

Clear Skies!
