First, if you don't know that 'MF' stands for Medium Format, you
should probably be reading about the Series III 'Stiletto' 35mm
and CCD focusers instead. But, if you do know what the capital
MF means, then you also know all about the capital PROBLEM it is to
focus on stars with these beasts! Most astrophotos come out looking
like a product of Hubble 1. But don't blame your optics. They're
fine!

The fact is, since the film area is so large in MFs, the film does not necessarily lie perfectly flat across the entire film plane. Combine this with fast refractors with non-optimal lens correctors and your photo session quickly turns into a bloated image beasty bash.

The good news is that if you own a PENTAX 67 or 645, MAMIYA 645,
HASSELBLAD, or KIEV medium format, you can reach pinpoint focus in
seconds. The Series III 'Stiletto' is a high precision focuser. The Series III attaches to your t-ring or coma corrector adapter the same way your camera does now since it employs a bayonet mount exactly like that on your camera. And, while the Series III MF models come pre-calibrated to the factory spec film-plane distance, its adjustable 'Stiletto' helical focusing mechanism allows
you to tweak focusing - all this without altering your camera at all!

But the best news of all is that the Series III is totally flexible and modular. With a simple change of its 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-edge option) allow you optimize focusing given the limitations of your own eyesight and the f-ratio you're shooting at. Our easy swap-in, swap-out procedure puts you in focus in seconds. It's guaranteed.

Visit our website today to read all the details about our MF
focusers. And remember, you really want to tame your beast, not kill
it...

Clear Skies!
Richard
