Dave,

Nice work on the closeup. How did you get the darkened sky background?

is this the wobble you talked about

No the wobble was in a single frame taken in the middle of the secquence. If you get the animation working you will see it.

As for not seeing the animation I assume that it is a setting somewhere in Firefox. If you still have IE on your harddisk then save the GIF to your harddisk, open IE and drop the GIF onto it. that should work then.

All images were 30 seconds. I was actually showing Saturn to my son in the telescope at the time and just kept pressing the shutter release of the camera evertime it finished its exposure. Funny how things just work out sometimes :P

That is some great work Michael Scully! Well done!

It wasn't too clouded here, but I didn't have the equipment to do the challenge.

Later, when I got home from work at 4am, the sky was very clear. Jupiter looked HUGE! overhead!

:shock:

Dave,

Michael,
To get rid of the background glow, you need to make a duplicate image in photoshop and give it a good gausian blur.
Then subtract it form the original image and hey presto, no skyglow :)
All credit to Michael O'Connel for the idea.

That's a superb effort Michael. Well done!

Just one thing to note is that after you apply the gaussian blur (usually with a large radius), it sometimes useful to reduce the brightness by say, 20-40%. Then, subtract this frame from the original.
However, it very much depends on the image.
