I thought the seeing was going to be good last night because I was imaging the Moon earlier and I was getting some patches of good seeing. But Jupiter is still very low in the sky, and there was a great deal of turbulence, the disc was wobbling like a jelly.
The top image is in B&W, and the lower colour. I say colour, although I'm having problems getting the correct colour because they are so subtle. Plus I have to use an orange of yellow filter to bring out any detail. Managed to capture
Ganymede and Io though, the gamma setting had to be raised to about 60% to pick them up.
Not much to see on Jupiter's disc, the
GRS is around the back :-(
These were taken with a Barlow lens attached to the Toucam. I unscrewed my 2 x Celestron lens from the Barlow tube and screwed it directly onto the Toucam. It produces a nice sized disc with more contrast. When I attach a filter and then the Barlow lens, it magnifies even more.
If I use the Barlow lens as per normal, the image (in these seeing conditions) seems lacking in contrast and detail.
I bought a Baader Crayford Focuser from DHinds. It arrived today, very prompt, I specified a day and it turned up at mid-day. Free postage and packing also :-)
wow!... a clear'ish night :-)
Here's a great mosaic by Stefan Lammel of the crater Aristarchus that I just found on the LPOD Photo Gallery site.
NASA's Mars Exploration Rover Spirit from the slopes of "Husband Hill."
As you can see from my seeing chart link, it's supposed to be good seeing tonight... we shall see ;-)
