Maarten de Vries
Maarten has had an interested in astronomy since he was a small boy. He's been a member of the Society since 1999. He's especially interested in photographing wide field deep space objects. His equipment comprises of a Helios Apollo 150 f/6.7 short tube newtonian, a Helios Startravel 102 f/5 refractor and a German Equatorial mount with dual axis drives. For imaging he uses either a Pentax K1000 SLR, a Minolta S404 (4Mpix digital camera), a QuickCam Express modified web camera, or a purpose built high sensitivity 640x480 pixels colour video camera using a Sony CCD chip from a decommissioned video conferencing system.
Two photo's take afocally through my StarTravel 102 short tube refractor. The left image was taking through a 25mm eyepiece at 1/125 second F8.0. This was the moon at approximately 10pm with the shadow of the earth covering almost half of the moon. The image on the right was taken using a 32mm eyepiece at 4 seconds f3.6 when the moon was nearly fully eclipsed.
I took this image early in the year 2001 using a very cheap but heavy Zenit 11 camera with standard lens. I piggybacked this on my Helios Apollo 150 with driven EQ3/2 mount. The exposure was 5 minutes on Agfa 200 film. I then scanned the photograph and zoomed in on this region. The results are remarkable despite the low cost of the camera and you can even see a glimpse of the Horsehead Nebula!
I made this photo of the partial solar eclipse from the garden of our holiday cottage in Aberlemno in Angus on 3 October 2005 at around the maximum. The sky was excellent with the exception of a few contrails and a very slight haze. I made this image using a Minolta Dimage s404 digital camera on maximum zoom through one of the lenses of Baader Exclipse Glasses.
This picture of the Pleiades star cluster (M45) was taken on September 2002 from Knockban near Munlochy using a Pentax K1000 at the prime focus of a Helios Startravel 102 on a dual axis driven EQ3/2 mount. The focal ratio of the setup was f/5 and the exposure was 5 minutes on Kodak 200 asa film.
This image from the star clusters NGC 869 and NGC 884 (both known as the double cluster) was taken from Knockbain near Munlochy on 21 September 2002 using a Pentax K1000 at the prime focus of a Helios Star Travel 102 on a driven EQ3/2 mount using a 5 minute exposure on a Kodak 200 asa film.
