Black impact mark on Jupiter

Posted By Anthony Wesley
Yes, believe it or not, it seems that Jupiter has been hit by something and there is a jet black impact mark near its south pole. Here is an image I captured a couple of hours ago - if you have the chance to get out and see this longitude yourself then you should do it!

This sort of thing doesn't happen very often. The last one I remember was the Shoemaker-Levy impacts in 1994.

I have a page where I'll be putting my images and reports on this:

Jupiter, 4th August

Posted By Anthony Wesley
Here's an image of Jupiter from last night in very good seeing. I think this is getting close to the limits of my scope.

Mars, Nov 17

Posted By Anthony Wesley
Here are a couple of Mars images from the morning of Nov 17, despite the very low altitude the seeing was not too bad, and I used a 742nm Astronomik IR pass filter as my "red" channel to improve contrast.

Mars Dec 6

Posted By Anthony Wesley
Here is an image of Mars from this morning in average seeing, it's slowly getting larger and better placed for us southerners to image...

2 minutes capture per channel in IR (742nm) @ 44fps , G @ 50fps, B @ 40fps
Stacked best 2000 frames per channel.

The limb artifact is still present but somewhat reduced due to better seeing for this image compared to the last one a few days ago.

There appears to be some bright material in a line just below the North pole (at bottom), is this dust?

All,

Here is an image of Jupiter taken not long after sunset a couple of nights ago. Oval BA can be seen (just) at the top right.

Saturn, Feb 18

Posted By Anthony Wesley
After weeks of rain and clouds it was nice to see a clear night and steady seeing for a change!

This image of Saturn was taken jut after 3am this morning, you can see Titan to the top left and Tethys to the left just above the rings (it's faint).

Taken with my 14.5" scope.

cheers, Anthony

Saturn animation, Feb 19

Posted By Anthony Wesley
Here's a 6 frame animation of Saturn from Feb 19, I wasn't happy with the normal animated-gif style as it loses a lot of image quality, so I've butchered up a javascript animator that shows the original jpegs much better.

The animation shows Rhea in transit as well as its shadow and a good amount of low-contrast cloud detail.

regards, Bird
