First, the adapter seemed pretty heavy and with the camera, a Nikon D60, it was. The ETX needed a

The main yoke and jaw are die-cast, probably from zinc as it feels heavier than aluminum. The camera platform is hard plastic.

When I bought my telescope four or five years ago I was, like most beginners I guess, concerned with magnification. My Orion Skywatcher 90 EQ came standard with 25 mm and 10 mm Kellners and my first addition was an Orion Shorty Barlows. Inserting the Barlows before the diagonal and using the 10 mm the little Skywatcher can get up to 270 x magnification – a pretty useless number in reality as the optical train, aperture and mount cannot do it any justice. Magnification quickly gave way to a desire for medium power views and the next eyepiece to be purchased was a 17 mm Orion Explorer II Kellner.

Schmidt-Cassegrain catadioptric telescopes are a very popular hardware choice in amateur astronomy, for a number of reasons. They are good for visual observing, astrophotography, and CCD imaging. They are compact and deliver a lot of aperture in relatively small, portable packages.

A friend with a C-8 told me had a Lumicon Easy Guider and he offered me the chance to try it out. Well the first night I had it out I easily mastered its use and took quite acceptable photos thru the guider. I then brought one myself and for the last 5 years have been getting very satisfactory results from it.
