Bahtinov Focus Mask - astrophotography Celestron 4SE
 |
| The Bahtinov mask is a device used to accurately focus astronomical telescopes. The Bahtinov mask consists of three separate grids, positioned in such a way that the grids produce three angled diffraction spikes at the focal plane of the instrument for each bright image element (star).

| Bright star near perfect focus using Bahtinov Mask. Optimum focus is achieved when the middle spike is centered on the star and symmetrically positioned between the other two spikes. Small deviations from optimal focus are easily visible. Bahtinov mask, Celestron NexStar 4SE, Canon 40D |

Total Lunar Eclipse December 21, 2010 Winter Solstice
Total Lunar Eclipse December 21, 2010
New York, NY Celestron 4SE telescope. All exposures were taken with Canon 40D. Backyard astronomy and digital astrophotography. Weather in New Your during the eclipse time was fantastic, but a little bit cold.
The eclipse of December 21 2010 Tuesday morning was the first total lunar eclipse to occur on the day of the Northern Winter Solstice - the shortest day and longest night of the year (Southern Summer Solstice) since 1638 (first time in 372 years), and only the second in the Common Era. That will not happen again until 2094.
The eclipse was the first total lunar eclipse in almost three years, since the February 2008 total lunar eclipse. It is the second of two lunar eclipses in 2010.
Partial eclipse begins 1:33am EST
Total eclipse begins 2:41am EST
Middle of eclipse 3:17am EST
Total eclipse ends 3:53am EST
Partial eclipse ends 5:01am EST

Hyginus is a small lunar caldera located at the east end of the Sinus
Medii. Its rim is split by a long, linear rille that branches to the
northwest and to the east-southeast for a total length of 220
kilometers
Between two seas: Mare Tranquillitatis (Latin for Sea of Tranquility) and Mare Serenitatis (the "Sea of Serenity"). Apollo 15 landing at site Hadley–Apennine region.
Tycho is a relatively young crater (about 108 million years). This age suggests that the impactor may have been a member of the Baptistina family of asteroids. A larger asteroid from the same family may have been the impactor responsible for creating Chicxulub Crater on Earth 65 million years ago, and causing the extinction of the dinosaurs.
Copernicus is a lunar crater named after the astronomer Nicolaus Copernicus. The crater is located in eastern Oceanus Procellarum. It is estimated to be about 800 million years old. The circular rim has a 30 km wide. The crater rays spread as far as 800 kilometers across the surrounding mare.
