Jupiter on April 29 2006, from Gournes. Reduced to 75% size. |
 |
Saturn on April 22 2006, from Gournes. This night I used an UV/IR blocking filter, which lead to much better colour balance. Captured through a 5x Powermate and an extension tube, resulting in ~f/40. Three of Saturn's satellites are (barely) visible, plus a background star. |
 |
Mars from my balcony in Gournes, on Nov 12 2005. This night I used 2x + 5x barlow, resulting in ~f/60. |
 |
Mars from Juchtas, 26 Oct 2005. Notice how the south polar cap (on top) has receded since Oct 24. |
 |
I'm back in Crete, and my first trip to my favourite location, Juchtas, resulted in my best Mars images to date. Plus, I finally have a working tracking platform! This time I also used a Baader fringe killer filter, which resulted in a far better colour balance, compared to my 2003 Mars images below. Captured with a 5x barlow, resulting in an effective focal ratio around 30, on 24 Oct 2005. |
 |
Finally, a decent image of Saturn! Captured at f/25 on Feb 18 2004 at 20:25 UT. 139 of 1008 frames stacked. |
 |
I did some histogram adjustments in a portion of the frame to bring out several satellites. Did I capture 12.9 magnitude Mimas very close to Saturn? |
 |
Mars on Aug 13, 23:09 UT. Captured at f/25, ~ 170 of 560 frames stacked. |
 |
Mars on Aug 7, 2003. Captured at f/25, ~ 200 of 900 frames stacked. |
 |
Mars on July 28 2003, 23:40 UT. Captured at f/25, ~ 200 of 750 frames stacked. Click here to see an animation made from 50 consecutive raw frames, illustrating the seeing. |
 |
My first Jupiter with my new tracking platform! However, I have rather serious vibration from the motors, so the finest details have been washed out. Mar 26 2003. Captured at f/25, ~ 100 frames stacked. |
 |
Ganymede (top) and Callisto, two satellites of Jupiter, captured on Mar 10 2003. It is clear that Callisto is smaller and has a much lower surface reflectance than Ganymede. This time I used my 5x barlow, which gives a high magnification. Hand tracking at this power is a real challenge. Stack of nine frames, 200% size. |
 |
Venus on July 10 2002. The planet was very low in the sky, so there was a lot of blurring and atmospheric aberration. |
 |
Apr 02 2002. Jupiter with yellow Io and its shadow. |
 |
Apr 02 2002. 5 moons of Saturn can be seen. From left: Rhea, Tethys, Dio, Enceladus, Titan. You may have to increase your screen brightness to see Enceladus. |
 |
Mar 21 2002. 30 frames. The white dot above the great red spot is Europa, while the dark spot is not a shadow, but Callisto, which has a low albedo. |
 |
Mar 14 2002. Jupiter and Europa. Stack of ~60 frames. |
 |
Feb 26 2002. Stack of 30 frames, 200% size. |
 |
Feb 23 2002. Jupiter is a stack of 32 frames, while the moons are single frames pasted into the image. From left: Europa, Io, Ganymede, Callisto. You may have to increase your screen brightness to see Callisto at the far right. |
 |
Feb 22 2002. Saturn, with Titan barely visible (you may have to increase your screen brightness) in the upper left corner in the full picture. Mosaic of a stack of 23 frames of Saturn, and a single frame showing Titan. |
 |
First light with new telescope and new web camera! 10" Teleport, 2x barlow and Philips Toucam Pro webcamera. Ganymede at right. Stack of 18 frames. 29 Jan 2002. 200% size. |
 |
Saturn. Stack of 80 images. Logitech quickcam express, ETX90. 30 Nov 2001. |
 |
My first attempt at webcamera astrophotography. Jupiter. Stack of 70 images. Logitech quickcam express, ETX90. 30 Nov 2001. |
