The 92 Stowaway’s Field Flattener (92FF) 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.
To make your imaging convenient and precise we have incorporated a circular dovetail system into our modern flatteners and TCCs that we 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.
We are producing adapters for the popular Canon EOS and Nikon DSLR cameras (DSLR25EOS & DSLR25NIK). If you have a CCD camera system, we recommend having a custom adapter made through Precise Parts. The Stowaway 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.
