Jupiter GRS, Io & Callisto

Recommended Posts

I was able to capture some nice images of Jupiter as it approaches opposition with the GRS visible, an Io transit (along with a distinct shadow), and Callisto nearby. Jupiter was at high elevation, almost directly overhead, with excellent seeing.

Io was completing its transit as the GRS was rotating into view.  Callisto is off to the right in this image:

The GRS is near the center of Jupiter with Io to the upper right and Callisto to the lower right:

Opposition is next weekend, the night of November 2-3!

Nicely done Reggie,

If I may offer some, hopefully, constructive critique, perhaps hold back on the processing a tad, as I think a softer version might be more aesthetic.

Thanks, Goef. I go back and forth with the processing. Sometimes, I go for bold, rich colors and strong textures. Other times, I choose softer hues and subtle lines. I end up processing images multiple times for different effects. It all depends on my mood. I appreciate the feedback ;)

Excellent Reggie, good too see the Mak 180 "planet killer" do the business!

Thanks, Pete. Yes, the 180 really does its job. I'm glad I went for it and bought one so many years ago.

I think these are much better Reggie. They look really good. My planetary imaging teacher & mentor used to keep saying to me, 'whoa there Trigger, you're not making pizza'.....

Haha, I like "you're not making pizza"! That's going to stick with me ;)

Much better ... In my opinion anyway ,👍🏻

Thanks, knobby. I like both; the bold colors and strong textures of the first set appeal to me, but the subtle hues and delicate lines of the second set are beautiful!
