2,5" Field Flattener for Astro Physics 92mm Stowaway and older 105mm EDT Traveler

The 92 Stowaway’s Field Flattener for the  Astro-Physics 92mm f/6.65 Stowaway (#1400092 , € 5275,-) is used to correct the field curvature that is inherent in all refracting telescopes. It will provide pin point stars to the very corners of a full frame camera sensor and has a corrected image circle of approximately 50 mm.

Requires a 2,5"- DoveLoc-Adapter That comes with the 92mm f/6.65 Stowaway. The system is also compatible with the older Astro Physics 105mm EDT Traveler (the specifications are for the 92mm Stowaway, not for the Traveler). If you are using a Traveler, you will also need to purchase the 2.5" DoveLoc End Cap for AP 2.7" Focusers (EC2725)

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, 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 f/6.65 Stowaway (#1400092 , € 5275,-) uses a very robust 2.5” focuser, however we caution you not try to hang 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.
