Hello All,
This morning I managed to get out of bed after only 2 hours of sleep to start imaging on Jupiter. When I saw Jupiter in the south-eastern sky through the trees, I just had to drag myself outside, and set up my equipment.

This time I tried something new; instead of my usual Ir-RGB method (using a color wecbam for RGB, and the b/w webcam for Ir), I wanted to only use my b/w webcam to get a color image.

Now there was only one problem; I don't have proper R,G,B filters, so I had to improvise a little.

For the red channel I used an astronomik planet pro Ir-pass filter (>742nm). For green a W21 orange filter, and for blue a W47 blue filter.

The b/w Toucam Pro II webcam was used on my 10" Starfinder telescope (with a 2x barlow) to get the images.

Io can be seen on the far left, and the GRS is starting to appear from the upper right.

Jupiter was at 19 degrees altitude when I shot this image. This year, it's maximum altitude at my location will be about 22 degrees.

Nice going Emil! Those filter substitutions seem to have worked nicely for Jupiter (Io's a little red on my screen.) I visited your website, I like your animations and work, and all the more so because of your latitude!

That's a very very nice image for the altitude! Heaps of detail.

The normally red areas are a bit yellow to me??

Thank you all!

Mike, the difference between the red and green channels aren't very big, I think that is what is causing the yellowish look. Of course I could tune it more in Photoshop, but I didn't want to do that this time, because I wanted to see what these filters actually did.
I probably need a 'greener' filter for the green channel next time (instead of the orange filter). But still, there are colors in this image, and I'm very happy about that :)

Here's an even bigger version of the image (added another 25% in size, the original image was already resized to 133%)
