Moon and Jupiter

A great image of the moon and Jupiter (upper left of moon).  From Sky and Telescope, "Although they look close together, the Moon is only 1.3 light-seconds distant from Earth, while Jupiter is 1,700 times farther away at a distance of 37 light-minutes."  Couldn't have said it better myself. 
Taken with a Canon DSLR and 100 ISO.  Less than one second exposure time and focused as good as I could get it from Lubbock, TX on January 21, 2013.

Rosette Nebula

Located in the constellation Monoceros, the Rosette Nebula is an awesome photographic image that truly looks like a rose pedal.  Located some 1500 light years away, the Rosette Nebula shows its huge hydrogen ejection carried off by the stellar cosmic winds.  Taken in my back yard in Lubbock, TX under mild light pollution. 
Imaged with a QHY8 CCD and Hyperstar focal reducer.  This is an f/2 image and autoguided.  10min exposure X 15 images stacked for a final image.
Equipment included my Celestron 11" Edge HD and CGE Pro Mount.

The second image is the same object taken the same night, but reprocessed a little different.  Thanks to a Facebook friend for the reprocessing.

Spiral Galaxy NGC 2841 is found in the constellation Ursa Major shows dust lanes with a bright nucleus.  Around the galaxy are fainter smaller galaxies in the image in the upper left corner.  NGC 2841 has a diameter that stretches 150,000 light years across and is about 30 million light years away.

Imaged in Fort Davis, TX on January 12, 2013 using a QHY8 CCD camera.  Equipment included the 11" Edge HD and CGE Pro mount.  Autoguided using the popular ORION Single Shot Autoguider.  This is a 10 minute exposure with a total exposure time of 160 minutes total time.

Reprocessed after the first image post.  01/15/2013
