A historic location…

Old stuff Posted on Mon, October 31, 2011 14:29:00

After the meteor day on 29 oktobe, which was organised by de DMS, WGM and VVS, Inneke Vanderkerken and Michel Vandeputte stayed at my home on Sunday. After a long walk with the dogs we drove to the nice villages of Elburg and Harderwijk. Near Harderwijk we also take a look at an old “historical” location. The water tower in the woods near Harderwijk where in the 80s and early 90s the old meteor observing team Delphinus observed. On the roof of this tower we observed during many nights.
Besides many Perseid campaigns also many activities outside of the big streams were performed. The last meteor action from the water tower were the Leonids of 1993.

eta Carina nebula

Astrotrac/Polarie Posted on Mon, October 31, 2011 14:11:57

The Carina Nebula (also known as the Great Nebula in Carina, the Eta Carina Nebula, or NGC 3372) is a large bright nebula that surrounds several open clusters of stars. Eta Carinae and HD 93129A, two of the most massive and luminous stars in our Milky Way galaxy, are among them. The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth. It appears in the constellation of Carina, and is located in the Carina–Sagittarius Arm. The nebula contains multiple O-type stars.

The nebula is one of the largest diffuse nebulae in our skies. Although it is some four times as large and even brighter than the famous Orion Nebula, the Carina Nebula is much less well known, due to its location far in the Southern Hemisphere (text from http://en.wikipedia.org/wiki/Carina_Nebula )

Unfortunately, de images I took from this object were not quite sharp…

Centaurus-A and Omega Centauri

Astrotrac/Polarie Posted on 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.

Southern delta Aquariids

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.
