What did I miss tonight?

Posted By Andrew Chatman

I only captured a moment in time. See my post just below about my first Jupiter photo. Captured the Ganymede shadow transit, and Europa and Io outside the disk.

My first digital Jupiter

There are three moons, a shadow and the GRS visible in this photo. Here is a labelled view. Andy

Well, "close-in" is a relative term when shooting through a 70mm scope :-)

Notice the very faint magnitude 15.2 galaxy IC 4263 near the bottom of the photo, just right of center. Shows up as a small horizontal fuzzy line.

And a closeup of the "T-shaped" prominence

Well, I had 10 minutes to kill.

I created an Earth-size graphic by dividing an orb the size of the Sun by 109.

I then placed a row of those Earths to represent how large today's prominence was. The result: Pretty big! While not scientific, it looks like 17 Earths x 8 Earths.

OOPS, accidentally deleted the first post in the thread. Here it is again.

Here is a full disk shot showing a very nice "T-shaped" prominence.

M67 Open Cluster

Posted By Andrew Chatman

Wow Dennis,

like a box of jewels. I like yours better than the software's! The diffraction spikes are perfect on these clusters.

It's tough to have such problems as no h-alpha filter that fits! At least it gives the rest of us a chance to catch up.

Have a good weekend. Andy
