Astro-Physics 0,80x Focal Reducer/CCD Telecompressor
The 92 Stowaway’s Telecompressor Corrector is used to provide 0.80x image reduction while correcting the field curvature that is inherent in all refracting telescopes. It will provide pin point stars to the very corners of an APS-C camera sensor. It has a corrected image circle of approximately 40 mm.
To make your imaging convenient and precise Astro-Physics has incorporated a circular dovetail system into our modern flatteners and TCCs that Astro-Physics call the “DoveLoc”. Three uniquely machined thumbscrews pull the flattener or TCC into a tight and secure lock that makes the optics perfectly orthogonal. What adds to the convenience of the DoveLoc is that loosening the thumbscrews allows your camera to be safely rotated for image composition.
Astro-Physics produces adapters for the popular Canon EOS and Nikon DSLR cameras (DSLR25EOS & DSLR25NIK). If you have another DSLR camera or CCD camera system, then we recommend having a custom adapter made through Precise Parts. The Build-An-Adapter tool has the information that you need and is easy to use.
The Astro-Physics 92mm f6.65 Stowaway (#1400092, € 4595,-) uses a very robust 2.5” focuser, however we caution against hanging a large and heavy CCD camera from the optical train. It is a small scope and meant to be portable and fun!
Machined aluminum covers are included.
If you are using a Traveler, you will also need to purchase the 2.5" DoveLoc End Cap for AP 2.7" Focusers.

Astro-Physics – High-end German Equatorial Mounts
HIGH-QUALITY PROFESSIONAL ASTRONOMICAL MOUNTS Keeping to the same quality standards that have made the fully-apochromatic refractors legendary, Roland Christen's company has been building German Equatorial GoTo mounts for more than three decades. Their proven stability, accuracy and durability is the reward for anyone who can endure the traditionally long delivery times. Two "el Capitan" mounts are working in the Antarctic for several years now, even at temperatures of -75°C. They are perhaps the most spectacular example of the durability of the sturdy Astro-Physics mounts and are representative for many more exemplars that often run for decades at our customers without failures. With a very accurate manufactured worm gear the Astro-Physics mounts are equally well-suited for smooth, effortless tracking of celestial objects as well as for all visual and photographic purposes. Astro-Physics supplies 4 mounts with 30kg to 135kg instrument load. The GTO 1100 and GTO 1600 series are especially remarkable, because they are fully transportable - despite their high instrument load. This is possible because the declination axis can be separated from the rest of the mount. Even the GTO 1600, with 90 kg instrument load, can be transported and set up by one person! The connection of the two...
