MesuMount 200 Review
Mar 20 2016  All these years the MesuMount200 served me very well. I’m yet to see any problem requiring a service. As a matter of fact I am yet to see a single frame that was lost due to the Mount. I think it nicely fits the niche of a midsize observatory or even a large field mount. It is priced very competitively. If you get one I’m sure you won’t regret making that decision.

CAPTURING COSMIC RAYS WITH A DIGITAL CAMERA
Mar 22 2016  Muons can be detected with cloud chambers, Geiger counters, and scintillator detectors, but can also be recorded with common digital camera CCD and CMOS chips which are sensitive to charged particles. Muon flux at the surface of the Earth averages approximately 1 particle per square centimeter per minute. The surface area of the APS-C camera sensor (22.3 x 14.9 mm) is 3.3 cm2, which means that we can expect on average 3 muon strikes on the sensor during a 1 minute exposure.

Binocular Universe: Into the Realm
Apr 01 2016  Bridging the constellations Coma Berenices and Virgo stands the Wild West for binocular astronomers, where only the brave trod. You may know it as the Coma-Virgo Realm of Galaxies. The Coma-Virgo galaxy cluster is the core of the Coma-Virgo supercluster, which embraces members far and wide. All of the galaxies within autumn’s Sculptor galaxy cluster, as well as our Milky Way as well as the rest of the Local Group of galaxies, are counted among the multitude.
