This coal loader station is located at the shore of river Danube near Esztergom, Hungary. The station was built in 1927 as destination of a six-kilometer-long cableway connecting the nearby coal mines with transporter ships. The daily capacity of this transport system was 1000 tons of coal slack but it was closed down in 1963. The station is abandoned since 1970.

The Hungarian-Slovakian border runs at the middle of the river.

NGC 246 - The Skull Nebula

This happy little fellow is a planetary nebula discovered by William Herschel in 1785. The Skull Nebula is located in the constellation Cetus. From our vantage point, it has an angular resolution of just 3.7 arcmin. The estimated diameter is about 2.3 light years, and is 1,600 light years from our planet. It has a fairly low surface brightness at around 11th magnitude. Quite often, visual observers can find the foreground stars overpowering when trying to locate this planetary nebula. The central star is fairly bright at 11.8 magnitude. The eastern limb of the nebula is brighter suggesting that it is interacting with the interstellar medium. This is an excellent example of how some objects exhibit bow waves truly reflecting the dynamics of the interstellar medium.

I tried to capture the ethereal shell of this planetary nebula. It reminds me of a crystal sphere just hanging in space. The teal and red colours of the planetary really seem to add an element of extra depth to the image.

Thanks for looking.

21/P Giacobini-Zinner passing through Auriga constellation
Image&credit: Pavel Váňa
Description: Comet 21/P crossed the Auriga constellation and it was a beautiful show. It passed near clusters like M36, M37, M38 and near beautiful nebulae IC 405 and NGC 1893.
That night I captured this I was sitting on a chair with notebook and I was learning linear algebra for my exam. It was a beautiful night, sometimes I looked at the sky and saw Milky Way, some meteors and I was thinking about that I am going to be a physicist who can look into space and discover something new, something special about it.

I am french and I hope that you will excuse my poor English.

Last night I shot the 21P comet near the M37 open cluster :

But I also shot it during the 2 previous nights to show its movement along lhe three open clusters in Auriga (M38-36-37) :

Moon in color 14,5%
Moon in color 14,5%

The Moon is usually seen in subtle shades of gray or yellow
The different colors are recognized to correspond to real differences in the chemical composition of the lunar surface. The blue shades reveal areas rich in ilmenite, which contains iron, titanium and oxygen, mainly titanium, while the orange and purple colors show relatively poor titanium and iron

The Dark Tower (HaLRGB) by Delberson Tiago de Souza, no Flickr

This was probably the best Saturn of the year and also the last one before dedicating myself to the professional appointments and travels that prevented me from taking photos as I have in recent weeks.
There are many visible details and each wavelength evolves better than others, for example, with the IR 685 filter the polar hexagon and its central eye stand out perfectly. With the L filter, the tracks on the planet give a real show.
For anyone to complain about both the Cassini division and Encke's division are easily visible and the only thing else is because of the Crepe ring that was practically missing. I could have highlighted it better but opted for a higher contrast rendering to evidence other details that were quoted above.

These September evenings were particularly dark at 21.5 SQM with an unusual Marine layer over San Diego this time of the year. 15-minute luminance subs hovered around 2.1" FWHM measured using CCDWare. In general, a very dark and steady period. Color shot with a 10 mph wind, but the direct drive L600 kept to within +/- 1".

At only about 7 Million lights years, NGC 55 is one of the closest galaxies to the Milky Way and allows us to peer deep inside her edge on structure a little easier than most galaxies.
