La "Super-Luna" de día 19/03/2011

Greetings to everyone.

After months without posting ( that does not mean that the rod on the internet ... ), today I return to the blog to post my contribution to the uproar caused (and is causing ) the Super- Luna .

not coiled much ( there are thousands of lines written in internet), on March 19, 2011 the Moon has been found at the closest point to Earth (perigee ) of the last 18 years (for More precisely, the moon has passed 356,575 km. of the Earth, when the average is 384,400 km.). And as a curiosity ... the next time will pass so close in 20 years!

This has created quite a stir, from those who simply enjoy to observe the moon and really appreciate a little more "big and bright", even those who have grown doomsday theories in which, because of the gravitational force Moon, major natural disasters would occur on Earth (earthquakes, tsunamis, etc ... No, what Japan has nothing to do with the Super-Moon ... I think ..., P or so say specialists ...)

Well, regardless of what one thinks, the truth is that if you like astronomy (or at least it stings a little curiosity all that is over our heads), this was a good opportunity to see our beloved satellite.

Internet is filled with photographs of such an event, everyone wanted to immortalize the Super-Luna, social networks have been the premier showcase for sharing this moment or # # superluna Supermoon. And of course, a server could not avoid it and joined the "fever" of the Super-moon, so I mounted my astronomical equipment (a f5 SkyWatcher 200/1000) and tried to attach the Nikon D90 (with and without eye / with and without lens) to see out, and after several tests and some processing with Photoshop, this is the result. Here my contribution:


- Technique used:

Nikon D90 at prime focus (attached directly to pulse and aimless, the telescope's eyepiece holder) 200/1000 f5 reflector (without eyepiece). Light processing with photoshop to highlight details. ISO 200 to 1/2500s. The telescope aperture is f5 (which makes target ...).

to see if someday I do with the adapter ring to attach the camera body to the slide-eye " automatically, without having to hold the camera to pulse ... (Deep sky, here I come!;)

I also did a test with the phone. I put it directly onto the eyepiece of the telescope and the application to make a couple photos I took. No big deal since it is not very clear, but hey, being with a mobile pa;) (a Nexus One # android). Here the links to Yfrog after upload photos to your mobile phone, without retouching or anything:

I must admit that I like to observe / photograph the moon when not in full moon, because, in part to reflect a lot of light, do not appreciate the details of the surface. The best time to observe it in the quarter waxing and waning (and the days leading up to them.) During these phases, the Sun's rays cause shadows on the moon's surface allowing better appreciate the details of craters and other accidents. Where best seen these details is in the area called terminator ( the line between day and night on the Moon ). Here is a picture I took some time ago with my Canon G9 on the same telescope, but using the eyepiece:

Nothing more, here my contribution to the Super- Luna. Have fun and do not forget to raise your head at night once in a while;) Byez!
