"Teaching young minds about the heavens"
The Heavens declare the glory of God; the skies proclaim the work of his hands.
Day after day they pour forth speech; night after night they display knowledge.
Psalm 19:1-2



Comet Images
C2011 L4 PanSTARRS
When it was discovered in 2011 it was thought to be a Non-periodic comet which will most likely never return to the inner solar system. This occurs when the comet exceeds the escape velocity of the sun as it passes so it will never return. It was discovered by the Pan-STARRS telescope near Mt. Haleakala on the island of Maui in Hawaii in June of 2011. The current estimation of the orbital period is roughly 106,000 years and probably came from the Ort Cloud way beyond the orbit of Pluto (formerly known as the ninth planet) and had its orbit disturbed when it either collided with another object or interacted with one gravitationally.

This image taken using a Canon 10D DSRL and a 75mm lens. It is a composite of six four-second exposures. You can see the very thin crescent moon at the bottom right in the trees.

17/P Holmes
This is a short period comet with an orbit of about 6.8 years. Usually it is not visable except through larger telescopes. On about October 24, 2007 it suddenly brightened by a factor of 15 magnitudes, or about 500,000 times, to magnitude 2.5 making it look like a bright yellow star to the naked eye.
Images were taken using my Meade LX-90 and a Canon 10D at prime focus. It is obvious that the star-like nucleus is not directly centered on the coma. There are also quite dramatic changes from day to day.
