This is a 7.1 inch f/10 Maksutov Cassegrain manufactured by the Russian company Intes Micro. I purchased this scope from ITE Telescopes in February, 2003. It arrived a few weeks later after a stop-over in Jupiter, FL for a collimation and certification by Mike Palermiti. The scope is the standard coatings version with a certified final wavefront error of one-sixth wave and 0.7 arc second bench-test resolution.
I own two achromatic Stellarvue telescopes, the 80/9D and the Nighthawk that I use for visual observation. Both have 80mm diameter doublet objective lenses, with the former having a focal length of 750mm (f/9.4) and the latter 480mm (f/6). I bought these telescopes as a complement to my first telescope, a Celestron 8 inch (f/5) reflector. The Celestron is a respectable moderate-aperture telescope suitable for observing rather dim and diffuse deep-sky objects, especially at dark sky sites or when you have plenty of time for set-up/tear-down and to let the temperature of the optical tube assembly reach equilibrium with the surroundings to achieve decent views.
Saturday Jim Richberg and I got together with our Coronado Personal Solar Telescopes (PSTs). There were two tests we wanted to test: a side by side comparison of the two PSTs and to conduct a PST eyepiece shootout.
The Coronado Personal Solar Telescope (PST) is a wonderful way to look at the sun in Hydrogen-alpha, and has produced a legion of new “solar addicts” in the short time since its release. One of the limitations of this scope compared to Coronado’s higher end products was its inability to come to focus with binoviewers, even with fairly significant Barlowing.
Not too often do we come across a very inexpensive piece of equipment that can make such a difference in the way we go about this wonderful hobby of ours. One of my least favorite aspects of the hobby is the drudgery of packing everything after an evening of stargazing. This is especially so during the months of January and February where it seems that Crockett Park is the coldest spot on earth.
This low-cost Chinese-made refractor has only been on the market nine months, but already it appears Orion’s new 80mm ED f/7.5 scope is a huge hit. Indeed, the Orion ED users yahoo group has grown from some 30 members in October 2003 to nearly 500 in May 2004
