Eclips 21 june 2001. Video recordings Compilation from the video recordings made at Kotwa, Zimbabwe. The picture showing the corona has been heavily processed to show more details. All pictures have been processed with AstroStack (copyright R.J. Stekelenburg).


This page shows some of the examples and also the improvements I was able to make over the years. Click on any of the thumbnails to see the images in full format. Most pictures where made with a 114 mm Newton telescope, unless otherwise stated.

1999

114 mm Newton telescope

Mars 18 May 1999 Mars 18 May 1999 (20:43 UT, diameter 15.5", Central Meridian estimated at 232º)
The seeing during the opposition of Mars was bad. This one was the result of using as many frames as possible (about 190 usable frames from a total of 420).

2003

140 mm Maksutov telescope

Mars 21 august Mars 20 august 2003 ca. 23:00 UT

Mars taken through my Orion 140 mm Maksutov. Seeing was reasonable, but not really good. Used some 600 video frames.

250 mm Newton dobson telescope

Mars 6 october Mars 06 october 2005, 03:14 UT

Mars taken with a 250mm Newton dobson. Seeing was good, transparency bad (mag 4 stars). Used 90 video frames. (Camera: Phillips ToUCam-2)


Mars 18 october Mars 18 october 2005, 03:05 UT

Seeing was reasonable, Full moon nearby. Used 100 video frames. (Camera: SAC4-2)
Used 200 video frames. (Camera: SAC4-2)

Jupiter

Jupiter 21 September 1997 Jupiter 21 September 1997,
with the shadow of two moons (and possibly a glimpse of the Red Spot at the far left).

Jupiter three times Jupiter 21 September 1997
The pictures where taken within a timespan of one hour. I used the multiply feature of AstroStack here to get a nice contrast and to emphasize details.

Jupiter 12 November 1999 Jupiter 12 November 1999
A very steady night, my best result with the 114mm Newton.

Jupiter with 2 moons 12 November 1999 Jupiter with 2 moons 12 November 1999
A very steady night, my best result with the 114mm Newton.

Jupiter 11 January 2001 Jupiter 11 January 2001
With the 140mm Maksutov. Red spot is visible.

Jupiter with 4 moons June 2005 Jupiter with 4 moons and Ganymedes' shadow 22 June 2005
Bad seeing, low altitude, still the best result with the 140mm Maksutov.

Saturn 21 September 1997 Saturn 21 September 1997

Saturn 12 November 1999 Saturn 12 November 1999
A very steady night, my best result so far with the 114mm Newton. Combined from over 200 separate movie frames.

Saturn 12 november 1999 in color Saturn 12 november 1999 in color, enhanced Saturn 12 November 1999
Shot through a camcorder pointed at the eyepiece. Combined from 40 separate movie frames. Color saturation was increased.
Right is the same picture showing that 'enhancement' can introduce artifacts (look at Cassini's division)
You also see that there is not as much detail as in the black and white picture of the same date.

Solar eclipse 21 June 2001 ca. 13:17 UT. Kotwa, Zimbabwe.
The sun had a nice group of sunspots. During totality an enormous protuberans was visible. Jupiter was visible close to the sun (4th image from the left). According to some who had seen the 1999 eclips, the corona was not as beautifull as it was then.
However, it being my first solar eclipse, I thought it was awesome. Also watching the event together with the friendly local people, while overseeing the African savanne made it very special. The sound that I recorded together with the video, the whistling, screaming, chanting and singing, shows that this is a very special phenomenon, with a strong emotional impact on those watching it.

eclipse 21 june 2001 eclipse 21 june 2001
Some structure in the corona could be recorded (visible after image processing).

Shot with a Sony TRV125 Digital 8 video Camcorder.
In full tele the zoomlens is equivalent to a 1200 mm lens on a 35 mm photocamera. Combined 30 - 120 images with AstroStack .

 

sunspots 8 april 2001 Sunspots 8 April 2001 14:00 UT
Shot with a Sony TRV125 Digital 8 Camcorder. A home made filter** was fitted in front of the zoomlens. In full tele the zoomlens is equivalent to a 1200 mm lens on a 35 mm photocamera.

Sunspots August 1999 Sunspots in August 1999 (15 Kb)
The 'old fashioned' way: shot with a 35mm reflex camera with a 500 mm telelens on Kodak Elite slide film. Combination of two pictures. The telelens was also fitted with a filter**.

 **made from a piece of fully exposed and developed 35mm black & white film (Kodak 2415).

Solar Eclipse 1999 Solar Eclipse over Europe 11 August 1999 (52 Kb)

We didn't see much of the eclipsed Sun (it rained during the 'moment suprème', see the umbrella?), but it was still an impressive experience. We caught this series with a Hi8 Camcorder somewhere on a camping in France.

June 2001, Zimbabwe. The southern sky was great to watch, both with the naked eye and through modest binoculars. These pictures are from video taken with the camcorders nightshot mode. They are not particular good, but still serve to show what you see through modest equipment.
