Centaurus-A and Omega Centauri

Astrotrac/PolariePosted by Koen Miskotte Mon, October 31, 2011 11:56:54

On 3 august 2011 I took some pictures of Centaurus A and omega Centauri. Omega Centauri (left on the image) is a globular cluster with a total mass of 5 million suns! It is the largest globular cluster in the halo of our solar system. Dutch research done in the years 30 and 70 led to the conclusion that omega Centauri is possibly not a normal globular cluster, but that it was formed from a dwarf galaxy. The mass of an average globular cluster is in fact 100,000 suns.

Centaurus A (right on the image) is a large galaxy at a distance of 10-16 is one million kilometers of our galaxy. Both Cenaturus A and omega Centauri can be simultaneously recorded with a 200 mm telephoto lens.

During the first week at Hakos I used the Astrotrac Mount for two camera's with 15 mm and 35 mm lenses to capture some meteors. Here you find an image with two Southern Delta Aquariids.

Small Magellanic Cloud

Astrotrac/PolariePosted by Koen Miskotte Fri, October 28, 2011 16:14:53

Also during my stay in Hakos (NamibiĆ”), I ofcourse took pictures of the Small Magellanic Cloud. It is a irregular galaxy and it lies at a distance of 200 000 lightyears away from our own galaxy. Also visible on this picture are both globalar clusters 47 Tucana (the big one) and NGC 362 (the small one).

Large Magellanic Cloud

Astrotrac/PolariePosted by Koen Miskotte Fri, October 28, 2011 16:03:23

During the period of 25 july untill 7 august I stayed on the Hakos guestfarm in Namibia to observe the meteor stream the southern delta Aquariids. In the second week I also made some astropictures from many southern objects. Here you find the Large Magellanic Cloud (LMC). It is the third closest galaxy to our milkyway. It is only visible at the southern hemisphere.

Corona Australis Nebula

Astrotrac/PolariePosted by Koen Miskotte Sun, September 18, 2011 15:06:59

In the small constellation Corona Australis (Southern Crown) lies a 42 light-years away reflection nebula. It is the nearest region where new stars are formed. This nebula complex was photographed by me on August 3, 2011 at 23:30 UT. Afterwards, the positioning of this area could be better. Also visible is a Globulair starcluster called NGC 6723. Location: Hakos Guest Farm Namibia.

Antares and Rho Ophiuchi cloud complex

Astrotrac/PolariePosted by Koen Miskotte Sun, September 04, 2011 12:11:46

Finally I had some time to process an image from Namibia. This image (taken on 1 august 2011 around 00:37 UT) shows te bright star alpha Scorpio and the Antares/Rho Ophiuchi cloud complex. At the right side a bright meteor is visible, a Capricornid of -2. Also visible on this image are two globulair clusters named Messier 4 (left corner) and NGC 6144 (near Antares).
