Jupiter and a Comet 
On the night of 6 October I captured some more pictures of Jupiter. This one is a stack of 1440 frames, selected from 4000 captured with a ToUCam Pro 740 using K3CCDTools. Stacking and wavelet processing was done in Registax 5, while some further sharpening and cleaning up in The Gimp.

When capturing the images I thought that it looked rather steady. In fact the seeing turned out to be pretty good, and a reasonable result came out.

Earlier that evening I went looking for comet 103P/Hartley 2. This comet is getting slightly brighter, it is hoped that it will be visible (just) to the unaided eye over the next few days. After that the moon will be getting too bright to see it so well. It's currently in Cassiopeia, moving towards the double cluster in Perseus.

This picture was taken using my Canon EOS 300D. I took 14 photos of 40 seconds each, at ISO 800. They were combined using Deep Sky Stacker and further processed using PixInsight LE.

Comet 103P/Hartley2 
On 4 October I got my first view of a comet that's been raising hopes among amateur astronomers of seeing a brightish comet in our sky.

I still haven't seen Comet 103P/Hartley2 in binoculars, but I saw it the other day through my Megrez 80 telescope and captured this image.

This is a stack of 14x40second images, stacked using Deep Sky Stacker and processed using PixInsight LE.

The night was humid and hazy and getting more hazy - I tried to capture some more images through colour filters but by then the humidity in the air had increased to the point that even brighter stars were looking like comets.

Eclipse on Jupiter - Io passes by 

Io is of course one of the four Galilean moons of Jupiter. As these moons orbit the planet they from time to time pass by the planet leaving a shadow on the disk of Jupiter. These shadows can be easily seen from Earth.

I imaged Jupiter using my TouCam Pro on the night of 24 September. The first image (above) shows the shadow and Io itself.

Here are a couple more images of Jupiter from the same night, with Io now having passed by - Eclipse over!

These were all processed in Registax 5, with further tweaking in The Gimp.

My best ever image of Jupiter 
Here is an image of Jupiter I captured last night. The night was a little cloudy and I didn't expect great results. The image on my screen while capturing looked reasonable but very blurry.
However after capturing 2000 frames and stacking 864 of them it turns out to be the best image of Jupiter I have ever taken.


Optics: Orion Optics SPX 250 with AE 3x Imagemate
Camera: Philips ToUCam Pro 740 with Baader IR blocking filter
Processing: Align, stack, wavelets in Registax 5, light sharpening in The Gimp

I have heard it said in the past that a little haze can be good for planetary imaging, now I believe it!
