DSLR of Comet Machholz

Ivan,

A beautiful image of Comet Machholz (C/2004 Q2). You have captured the star-like nucleus, large diffuse coma, pencil-thin plasma (ion) tail, and dust tail (off to the side) very nicely. I look forward to your future images.

Chris,

Congratulations to you and Mr. Akutsu on the excellent images of the solar prominences and sunspot groups AR 712/713. The images show these impressive solar features very nicely in H-alpha. I look forward to your future images.

Hipparchus

Posted By Carlos E. Hernandez

I must apologize in that I mistakenly identified the large crater towards the west (left side of observation) as the crater Hipparchus. It is in fact a ghost crater that contains the crater Torricelli (4.6*S, 28.5*E; 14.3 miles (23 km) diameter) over it's northern portion. The prominent crater over the eastern (right) side of my observation is Capella (7.6*S, 34.9*E: 30.5 miles (49 km) diameter). I am sorry if my mistake had veteran lunar observers scratching their heads and saying "That does not look like the Hipparchus region." This proves that even veteran observers such as myself make silly mistakes. I have included a detailed section of an image from the Consolidated Lunar Atlas ( http://www.lpi.usra.edu/research/cla/info/e9/ ) for reference. I have included the crater Theophilus as a reference point.

Thank you for your understanding.

Christmas Eve Jupiter - 2 SEB Oval Storms?

Posted By Carlos E. Hernandez

Chris,

An excellent image of Jupiter obtained by yourself and Mr. Akutsu. The two small SEB ovals are interesting and need to be monitored in the future. The NEB-S blue festoon is interesting as well. I look forward to your future images.

Posted By Carlos E. Hernandez

Sol,

A wonderful observation of Saturn! Among the best that I have seen you produce to date. The detail over the globe is prominent, as you point out. Much variation on brightness is noted over the rings as well. I look forward to your future observations.

I hope that your holidays were enjoyable as well. Happy New Year!

Larry,

Thank you for posting your excellent image of Albategnius and Klein. These two craters are located just east of Ptolemaeus, close to the center of the Moon.
