Special Projects - "all nine", a
planetary parade
In the
Namibian winter of 2018 (July, August) it was practically possible to observe
all 8 planets (+ Pluto and the bright planetoid Vesta) in one night.
Here now pictures of the outer
planets and the bright planetoid Vesta.

VESTA
The
planetoid Vesta (4), 7.2 mag, taken on 14.09.2018. 6 x 120 seconds with 200mm
telescope lens. Additionally the picture shows the planetoids Adorea (268),
13.9 mag and Lilaea (213), 13.2 mag. Top left in the picture the planet

The
following pictures and animations were taken with a Celestron 14 and a 17 inch
Planewave astrograph. The used Video modules were a ZWO ASI 224, 290 and a
Celestron SkyRis 445 Mono. The focal lengths were partially extended with a
Baader Q-Turett Barlow element. A Baader IR pass filter was used for all
monochrome images. The quality of the images varies greatly with the local
seeing conditions during the acquisition of the raw
avi-files. |

« The picture on the left shows the best
picture of the planet Saturn, which we have imaged since 2013. Taken on 28 July
with the 17" PlaneWave of a ZWO ASI 290 and Baader IR passport filter. The
focal length was extended by a factor of 2.2 with a Baader Q-Turett Barlow
lens.
The picture shows a dark narrow line in the ring system on the
left and right. Here the Encke gap in the Saturn ring becomes partly
visible.
For a telescope with only
17" aperture a "small sensation", because the width of the gap is just about
300 kilometres according to measurements of Voyager space probe images. These
300 kilometres roughly correspond to only 0.05 arc seconds. |

The three
outer planets were only imaged with a telephoto lens. Uranus and Neptune stood
in a starless field, Pluto in a rich star field in the constellation
Sagittarius. Each 5 x 120 seconds exposed with a 200mm (f/4) telephoto lens at
ASA 800. All three images can be enlarged by clicking, the images are labeled
with the brightest field stars. Unfortunately, Pluto is not clearly
identifiable at this magnification. While the mages were taken, the moonlight
was still disturbing and causes the blue sky background.
On this website we show pictures
of Pluto, taken in 2015 at 24 hour intervals with a telescope of only 50mm
aperture. |
