160mm f7.5 StarFire EDF, 900GTO German Equatorial Mount, Portable Pier, and other accessories.
This 160mm StarFire EDF was designed from the ground up as a brand new instrument, not a mere modification of one of our earlier products.
Lens: Our exceptional, multi-coated triplet, air-spaced apochromat uses the latest in multi-coating technology with the highest grade of optical glass to achieve exceptional image brightness and excellent color correction. The close air-spaced design results in rapid cooldown during nighttime temperature swings. Color correction is ideal for all visual and imaging needs. The 1200mm focal length allows a full range of eyepiece designs from simple to complex to produce extremely sharp planetary images. Performance has already become legendary among imagers.
Tube assembly: Multiple baffles reduce stray light to a minimum. The lens resides in a push-pull cell that maintains its collimation even under conditions of vibration during shipping. The new sliding dewcap has a built-in baffle to help prevent dew as well as block stray light.
Focuser: The 160EDF comes standard with our 4" greaseless focuser, which was designed to hold all types of heavy equipment, while still moving smoothly without image shift. A built-in collar allows the focuser to rotate a full 360 degrees to suit. Focus travel is a generous 105mm (4.1"), and is positioned so that the Baader Planetarium Mark V Binocular Viewer will come to focus without the 1.25x compensator. This allows the user to see glorious wide-field views with both eyes - a real treat.
The giant 4" focuser will allow you to enjoy any and all of your astronomy pursuits. The 4" ID of the drawtube will allow maximum coverage of the Pentax 6 x 7 cm negative for medium format photography. The inside of the drawtube has a series of knife-edge baffles for maximum contrast. Choose from a full line of photographic accessories for CCD imaging, 35mm and medium format film photography. In addition to an optional 4" Prime Focus Field Flattener, we offer a dedicated f5.75 Flat-Field Telecompressor that is diffraction-limited over the entire 35mm field. Perfect for the new, large chips available today.
The Mach1GTO, 900GTO or 1200GTO German Equatorial mounts are all recommended for astrophotography, depending on your requirements for portability and the amount of wind you are likely to encounter at your photographic site.

The current production run of these superb instruments is coming to an end as this is being written in February, 2007. At this point in time, the next production run of 160 StarFire EDF refractors has not yet been scheduled. The notification list for these telescopes, which actually begins with the existing 155 StarFire EDF/EDFS list, is very long indeed. The production run that is currently coming to an end only brought the list into November of 1999. Plese refer to our availability page for more information on our notification lists and backorder history. To get on the 160 StarFire EDF Notification List, please use our Online Notification Request Form.
