planets at various mags (Blue Mountains)

Amazed to see Mars just above the hill...

Mars trailing up, above tree, from CAO grounds

Switched to subs, versus a single frame. 2 minute subs with a 2 second gap. Classic star trails.

9:49 PM. Spotted the Moon rising. It was a bit left of where I was expecting. Moved the camera.

Moon trailing up over the tree line from the CAO

I could see Mars in the initial shots. Didn't know if they would be together now, after moving the camera.

Stopped down to f/22.

Planned to let the rig go for an hour. I'd rescue around 10:45.

I noted a star below Mars: Dschubba or δ (delta) Scorpii. Directly.

Tried to see Saturn... Could not tag it. Probably washed out by the Moon...

Also noted Acrab (Graffias?) or β (beta) Sco to the left of Mars. [ed: Yes.] In a 90° angle with Mars to Dschubba.


Just remembered spotting a satellite, perhaps an Iridium, possibly around 9:20, in the south-east. [ed. Checked Heavens Above: no Iridiums at that time. Possibly the BREEZE-M DEB (TANK)...]


9:55. Slewed the Celestron 14-inch SCT atop the Paramount ME to Jupiter. I had been on Mars--to help eyeball it.

Huh! Only 3 moons... Scanned for shadows... No...

Io was going in... On the "one" side. I.e. same side as Callisto. Going in. According to SkyTools and the Context Viewer display.

Bumped the power with the 27mm Tele Vue eyepiece. Nice view. Seeing was fairly good.

I actually saw Io, as a white dot, in front of the disc, in front of the northern belt! It was not merging or touching the edge of the planet's disc as suggested by ST3P. When I zoomed into the software, it correctly portrayed it, over the planet. I had initially been thrown off by the course zoomed out display.


10:05. Spotted Saturn directly right of the Moon. Fantastically dim.


10:40. Grabbed the camera and tripod...

It kinda worked. I could see the Moon in the shots. It did not look completely burned out.
