A big thanks to all the Series III 'Stiletto' users.
Their ideas and suggestions have resulted in the most precise
focusing device for astrophotography: the new Series IV 'Stiletto'!
There are lots of new features in the Series IV, and we
invite you to visit our redesigned website to read all about them
since space here is limited.
The really big news is that along with improvements in our standard
Series IV model, we have introduced a totally new Professional
Edition with some great special features:
The Series IV Professional Edition incorporates our brand new
high resolution 'Black Chrome' ronchi screen. This is a 300 line/inch
black chromium ronchi grating etched on optical glass. It was
manufactured on the same machines used to etch integrated circuits.
That's how precise this screen is.
And as always, Series IV models are available for just about all
35mm, CCD, and Medium Format cameras with interchangeable mounts to
go from one format to the other on the fly. We have a model for you for
And while we were busy making the Series IV better, we managed to keep
costs down while incorporating high quality components. The result is
the Series IV 'Stiletto' represents extremely good value. We've held
the price of the Series IV Standard Model at $199. And the price of the Series IV Professional Edition is only $299 with a LOT of goodies included.
Thanks again to everyone who contributed ideas for the Series IV.
