Jupiter in the round

A quick look outside and its a clear night. I can't be bothered to set up the telescope, but I take a look through binoculars at Jupiter, which is looking quite clear. As I watch, I see the ISS go overhead!

Anyway, I decide its worth a photograph, so I get out the camera and tripod and take a few snaps at various settings to see what I can get. Its nothing like what you see in the telescope, but it makes for a nice assemblage.

If you zoom in, you can see the motion blur dragging the points out into streaks, and this is only a 10s exposure, but from a distance it looks pretty ok. Zoom in not quite so far and you can see some of the satellites.

Jupiter - another go

I had another shot at Jupiter last night. With the telescope on the patio, I have a window of about 15-20 minutes when it is visible between two trees. This time I got set up a little earlier and managed two separate imaging samples. The visibility wasn't that great with it low on the horizon, and again it didn't look as good through the LPI webcam as through the lens. I guess the old mark one eyeball still has a useful range and pixel density.
You can see three of the satellites however, so that's a little better.

Also this time I had the settings right so I could post process the images with registax, which I think does a better job than envisage.


I might try a different technique if I get a chance.

Jupiter

Its been a while - but now the nights are getting a little earlier and I can be bothered to stay up. Also there is a new jewel in the sky, in the shape of Jupiter, so its time to have a go and see what can be got.
Its not easy, Jupiter is low in the sky between some trees, and after a few goes, the only place I can get a good view of it is from in the middle of a wooden bridge. This is not ideal, as everytime I move, the image leaps around. Even so, its the first go and the images are okish, but would be better if I'd saved them in a better format.





Maybe another night I'll have a better go, and remember a few more things. You can see a couple of moons, but its not as clear as it is through the eyepiece.
