On January 22, 1916, while revisiting some of the stars in his Catalog and Measures of Double Stars discovered visually from 1905 to 1916 within 105° of the North Pole and under 5" Separation, French astronomer Robert Jonckheere returned to a vague double in Orion, which he had previously designated as entry number 320. Jonckheere was later to write of this encounter through the 28-inch refractor at the Royal Greenwich Observatory, "I noticed that the object I have catalogued as J 320 is not a double star, but, like J 475, it appears with the larger instrument to be an extremely small bright elongated nebula. As is the case with J 900, this object also appears to be new as a nebula."

So here are my thoughts. No matter how much you paid for a premium triplet, on most objects the 152MM can keep up with it. If you want to see no false color and need your ego stroked because the scope is not expensive, don't buy the APM. Get a TAK/TEC/AP, you'll feel better about yourself. If you consider the value, this scope is just an excellent buy. It’s like the EON version of the SW150. You get a better focuser/case/sliding dew shield/rings/ and a much prettier scope.

The Burgess 24mm Modified Erfle and 10mm Ultra Monocentric eyepieces are relatively new offerings from Burgess Optical. The Ultra Monocentric has been long promised so nice to see it finally coming to fruition.

In 1992 the face of our cosmos changed. What had been hoped for, dreamed of, was finally confirmed. Our solar system was indeed not unique in the galaxy and there were other planets orbiting distant stars!

This document is something I put together for the Daughter and her kids . It is a simple How TO Assemble/Setup the Evolution scope system. They are just beginning to learn how to setup-use the system and only use it a few times a month so far. So I thought this tutorial would make them more comfortable with the setup and storage of the system.

The Andromeda Galaxy, M31, was probably one of the first galaxies you ever saw first-hand. It was mine. That was all way back in 1969. Since then, I have grown to appreciate it as far more than just the ill-defined oval blur I drew in my logbook. But in 1969, the thought of looking for individual objects within M31 never crossed my mind.

M32 and M110 are nice challenges for handheld binoculars. Most amateurs are familiar with them, since they lie in the same field of view of the parent Andromeda Galaxy. But two others, designated as NGC 147 and NGC 185, are not as nearly well known. Both are several degrees to M31's north, across the border in Cassiopeia and feature smaller, fainter disks that are much more challenging to see.
