Notes on the 92mm f7 by R. Christen

You asked for this scope. For some, the original f5 Stowaway was too short for an all-purpose visual scope. This telescope sports the same lens as our legendary Traveler, but with a bit less aperture (92mm vs 105mm) and a little over 1/2 the weight. While the Traveler was intended for astrophotography, with formats as large as 6 x 7 cm, the 90 f7 Stowaway has a field size of 2" making it suitable for 35mm and CCD imaging. The scope sets up quickly on even the smallest mounts and gives excellent high contrast images on any object from large deep sky objects, to lunar and planetary views. As the name suggests, this tiny scope can come along with you in your travels, take up very little room and its light weight is a real advantage when you have to traverse half a mile of airport concourse.
