Mars Makes Close Approach This Month!
Every two years and two months (roughly) Earth and Mars come close together in a planetary alignment called "opposition". This means Mars is on the exact opposite side of the sky compared to the Sun. This is also when Mars is closest to Earth in their respective orbits, and in turn when Mars appears its largest in the sky. Mind you, not "twice the size of the full moon to the naked eye" as the common Internet hoax emails proclaim. But the visible disk of Mars is noticeably larger during these close approaches.
In a given work day, we each get 60 minutes of time for us. 30 is usually used at lunch with two additional 15 minutes breaks. Having a window seat at your office gives you an excellent use of any spare time during your break. For me, a little 60mm telescope perched on my window sill is all I need to entertain myself - assuming some celestial friends are in the neighbourhood!
Over the years, a number of phenomenal technologies have worked their way into our garden variety telescopes. Integrated dual axis motors controlled with a hand paddle, on board computers allowing GOTO and PUSHTO technologies, built in GPS chips and level north sensors. Now, Meade has brought it all together and then some with the all-new ETX-LS6. This portable ACF (Advanced Coma Free) optics telescope includes several new technologies that allow complete star alignment without user intervention. A technology Meade calls LightSwitch combines data from an Integrated Sensor Module (ISM), GPS location and Level North Technology (LNT) to allow the telescope not only to figure out where it is on Earth, but to also actually see the alignment stars and tweak the telescope's setup automatically - without the user's input! The integrated ECLIPS CCD camera then allows the user to take pictures of bright sky objects like the Moon and the planets - all without a computer!
The year 2009 is finally here! And its also the International Year of Astronomy - a very exciting time indeed. Astronomers around the globe are organized to participate in over a dozen "Global Projects" as part of IYA2009. I will be taking part in a few of the projects myself:
Meade
has once again entered the large (by amateur
standards) Dob market with the introduction of
the LightBridge 16. This replaces the outgoing
StarFinder 16" model, and honestly the two are
like night and day. The StarFinder was a huge
mass of white Sonotube and melamine with a
flimsy plastic focuser, drastically undersized
bearings and sticky, awkward motions. Meade
wouldn't be hard pressed to have the LightBridge
line surpass the StarFinder - which they did.
The LightBridge line is of much higher quality,
with smooth motions, a machined aluminium
Crayford style focuser, and actual metal
content! It's truss design coupled with an 80mm
electric fan on the primary ensure reasonable
cool down times (for a scope of this magnitude).
Overall, the LightBridge line seems light years
ahead.
