Last night there were a very thick fog covering the city of Östersund. In this photo you can see the fog lit up from beneath by the city lights. It's very interesting to see all the different colors from different type of light sources. One of the most known landmarks of Östersund is Rådhuset (City hall) and you can see the tower/spire of that building sticking up through the fog in center of the photo.

Asteroid 2004 BL86 Passes the Beehive - Timelapse

On January 26 & 27th Asteroid 2004 BL86 passed within 745,000 miles of the Earth. That is about 3 times the distance to the Moon. Traveling at 35,000 miles per hour the Asteroid flew in front of the Beehive Cluster, Messier 44 (M44). During the event I took 607 images of the pass. Due to clouds only 314 were usable. I created a video using these to show 78.5 mins of the Asteroid pass.

I've also done some time lapses :

[youtube]https://www.youtube.com/watch?v=27i0JRs ... e=youtu.be[/youtube]

December 26th, 2014. It was the first day of a trip in Iceland. Just few hours after landing I've seen the best nothern light of the week. This very impressive mountain is Kirkjufell, it means "mountain-church". I was very lucky to shot the aurora just as it took the same shape as the mountain ! Few seconds before or after it was not the same.

I took this image with the new Sony Alpha 7s that is realy very sensitive : its has a big sensor with only 12 millions pixels, and the readout noise is very low.

2015 is the last year to have a solar activity at its best : http://services.swpc.noaa.gov/images/so ... number.gif
May be that the begining of 2016 will allso be ok.

After we will have to wait 2021 or 2022 to have a good level of solar activity.

Vega star and Milky Way.

Vega will eventually become the brightest star in the sky in around 210,000 years, will attain a peak brightness of magnitude –0.81 in about 290,000 years and will be the brightest star in the sky for about 270,000 years

Orion Nebula by astrochuck, on Flickr

A 6 panel mosaic was used for Luminance (60x1min) Taken with a 11" Celestron EdgeHD with Hyperstar(F/2). and a QHY23M (60 min)
RGB was taken last year with a Astro-Tech AT65EDQ and a QHY9M(Red-5x600s
Green-5x600s Blue-5x600s) (2.5 hours)
The "core" of the nebula was emphasized with 6x60s Luminance filtered images taken with the EdgeHD @F/10. (6 min)

M77 Canadian-French-Hawaii Telescope/Hubble Space Telescope by Andre vd Hoeven, on Flickr

Recently I started working on crawling through some science databases of several large telescopes to see what data can be found in these archives. Some of the most interesting archives I found are, amongst others, the Subaru Telescope, the Gemini Telescopes, the Canadian-French-Hawaii-Telescope (CFHT) and of course the Hubble Legacy Archive.

This image shows a mosaic of Messier 77 made from data of two of these databases.
The widefield data was observed by the CFHT in visible light using Sloan u,g,r-filters, which is comparable to standard rgb. This image has a resolution of 0.28”/pixel, and is as far as I have found one of the most detailed images of this galaxies available.

The central part of this galaxy was observed by the Hubble Space Telescope and I used the data I generated for my price winning image of M77, which received a second place in the Hubble Hidden Treasures competition in 2012.

The data from the CFHT is really a great place to start. This 3,5 m / f 3.9 telescope has a huge ccd, comprised of 36 separate sensors, covering a field of 1x1 degree with a resolution of 0.18”/pixel. The total image is size is a mesmerising 340 Megapixels.

I downloaded the subimages of 2 ccd sensors covering M77 for this image in the mentioned filters and created an rgb image from this. The process of this I will describe in further detail during my workshop at the CEDIC conference in March in Austria and will be public after that.

Messier 77 / NGC 1068

Messier 77 was discovered by Pierre Méchain in 1780. Méchain communicated his discovery to Charles Messier, who listed the object in his famous catalog. Messier gave the following description: “A cluster of small stars which contains some nebulosity in the Whale and on the parallel of the star delta, reported of the 3rd mag. but which Messier estimates to be of the 5th. M. Mechain saw this cluster on the 29th Oct. 1780, in the form of a nebula.”

In 1848, Lord Rosse described the galaxy as having a spiral structure together with 14 other nebulae of spiral nature, which we now know to be galaxies.

Now it is known that M77 is a spiral galaxy at a distance of about 50 million light-years with a diameter of about 170.000 lightyears. At first sight, M77 looks like every an ordinary galaxy. However when examined closely some oddities appear. The core is much brighter than its direct surroundings. Spectral analysis reveals huge amounts of glowing gas present in the core, triggered by the presence of a black hole in the centre of the galaxy. The black hole is highly active and gaining mass by swallowing materials from the galaxy core. The cores of these types of galaxies are called AGN (Active Galactive Nuclei).

The galaxy belongs to the class of Seyfert galaxies that show clearly different spectral emission than ordinary galaxies, caused by the presence of huge amounts of gas not belonging to stars in the core.

Observations over a five day timespan with the Chandra X-ray observatory showed matter is being accelerated away from the core by the violent processes going on there. Over distances of up to 3000 light-years, material is ejected with speeds up to 2.5 million km/h, actively suppressing star formation near the core.

M77 is the largest member of a small group of galaxies which includes spiral galaxies NGC 1055 and NGC 1073 as well as five small, irregular galaxies located in the constellation of Cetus.
