Jupiter, Feb 11

Finally patience paid off and I had some decent seeing this morning, mostly around 8.5/10 with moments up to 9 or 9.5/10.

Here's an of Jupiter taken just before 6am local time.

Equipment: 13.1" f/5.5 newtonian, 5x powermate + filter wheel and Astronomik RGB filters,
PGR Dragonfly Express firewire camera
Linux + Coriander to capture, Win2k + Registax, Astra Image, Neat Image and GIMP to process.

Here's an alternative version, aesthetically I like this one better, but that may just be my monitor.

Anthony, gorgeous shot! Best Jupiter image so far this season (not that us northerners are going to really have a Jupiter season!) A very natural processing job, superb!

Hi Anthony,

outstanding stuff 8O Good to see your Dragonfly Express back and imaging. 8.5 - 9.5 seeing - wow - I experienced that once in my life and dream of is since then. Jupiter won't be fun on the northern hemisphere for some years, great you share these outstanding images from down under.

Clear skies!

Bravo Anthony! On my monitor the first image is a bit more natural in processing, the second a little more detailed from sharpening - both are excellent.

As many have said, this will be the southern hemisphere's apparition of Jupiter - I look forward to following it through your images.

best -
Alan

A very stunning image Anthony!

I hope you will indulge me for just one more image... this one will be the final image from this session.

I spent more time on noise reduction and careful processing and colour balance.

In fact the red channel contains most of the detail - I've posted the 3 channels as well as the final composite so you can see that the other channels contain progressively less detail as the shorter wavelengths are harder to image.

Anthony -

I hope you will forgive my playing with your image. I don't expect to have data this good for many years! The detail shown in your red and green images inspired me to try a technique I used quite a bit last apparition - using red and green to make a luminance overlay for the RGB composite.

I sharpened the red and greed just a tad more than you had. I also blurred the very edge of the planet's disk a small amount with gaussian blur.

Let me know what you think of this variation.

Again - thanks for posting this great image.

Alan
