Moon

Naked eye
100 points

Nice 15%-ish crescent moon. I really like this phase of the moon: earth shine is prominent enough to be seen with the naked eye. Plus, the moon sets early enough to not interfere with other observations.

I made this observation through a break in the sky-soup. Here's to clear skies tonight.

From Red Rock State Park in California I observed the outer arm of the milky way. It appears as a dim "river of milk" through the sky, passing through Orion and Perseus. I had been able to see this side of the Milky Way before. Dark skies are amazing.

Great Orion Nebula

Mead LX200 (Cabrillo Observatory)
30 points

Orion is beautifully positioned in the sky right now, a constant reminder of why he is the single most recognizable constellation in the night sky. Orion, Canis Major and Taurus appear alive above us as they play out their celestial game of predator and prey.

This photo was taken back in November at Cabrillo Observatory using Spock. A favourite target for photographers, how could we pass it up?

I observed the Great Orion Nebula again tonight as I usually do during most sessions this time of y...

Jupiter

Orion 10" Dobsonian
110 points

My first look at Jupiter was through heavy light pollution and humidity so it wasn't very clear, but we could clearly make out 4 if not 5 moons. Looking forward to taking a closer look on a dark and clear night with a stronger eyepiece.

Moon

Orion 10" Dobsonian
110 points

I felt so close I was looking for first stages of Apollo LMs. The moon never disappoints.

Great Orion Nebula

Orion 10" Dobsonian
30 points

Great sighting. Mostly blue. Clearly visible through the 25mm Sirius Plossl eyepiece. A good bit of light pollution but was able to see the Nebula in good detail.

Fantastic shot. Well done!


The detail here is just fantastic. You must be an experienced sketcher. I like how prominent the windmill stars are.


Awesome you were able to observe Neptune and Uranus. They have been on my todo list for ages!
