This image shows the Double Cluster in the constellation of Perseus. The Double Cluster (also known as Caldwell 14) is the common name for the naked-eye open clusters NGC 869 and NGC 884 (often designated h Persei and χ Persei, respectively), which are close together in the constellation Perseus. NGC 869 and NGC 884 both lie at a distance of 7500 light years. NGC 869 has a mass of 3700 solar masses and NGC 884 weighs in at 2800 solar masses; however, later research has shown both clusters are surrounded with a very extensive halo of stars, with a total mass for the complex of at least 20,000 solar masses.

Based on their individual stars, the clusters are relatively young, both 12.8 million years old. In comparison, the Pleiades have an estimated age ranging from 75 million years to 150 million years. There are more than 300 blue-white super-giant stars in each of the clusters. The clusters are also blueshifted, with NGC 869 approaching Earth at a speed of 39 km/s and NGC 884 approaching at a similar speed of 38 km/s. Their hottest main sequence stars are of spectral type B0.

I started this image using my TMB92SS telescope with a QSI583, resulting in a LRGB image of this region.

When looking on the internet I found a wonderful image of Fabian Neyer of this region in H-alpha (http://www.starpointing.com/ccd/ngc869_ngc884.html).

After some mail contact with Fabian I decided to combine his H-alpha layer with my image to bring out this region in a way that is not very often shown. Huge clouds of hydrogen surround the clusters and show the complex interactions going on in this region.

The image consists of the following exposures:

André van der Hoeven:
TMB92SS - QSI583ws
L: 16 x 600s
R,G,B: 6 x 600s each

Fabian Neyer:
Televue NP101 - SBIG STL11000M
Ha: 66 x 1200s

Total exposure time: 27,7 hours

Hi, here is a YT Full HD movie with the ISS and the European cargo ATV-5, in transit in front of the Sun and during a nightime passage:

Geometry

This is one of the most intense moments i've ever experienced in my star gazing life, the crux, alfa and beta centauri near my horizon, the crux became a rhombus, this is one sigle exposure iso 5080 which produced a lot of noice and my camera's sensor was warm because of the long night of exposures making the post process a difficult task..., f3.5 and 30 sec. I needed to capture this moment that also displayed a greenish in the sky that was produced by airglow.

This was last weekend at General Belgrano, provincia de Buenos Aires, Argentina.

The Colorful IC 434- The Horsehead and the Flame

I took this with a non modified dslr over the course of two nights. I was astounded to see how much detail was visible, even with basic gear.

Autumn buckwheat galaxy

Buckwheat(SOBA) is a traditional Japanese food.
However red buckwheat is invaluable.
I found a red buckwheat in woodlands of Achi village.
Beautiful buckwheat field under the Milky Way.
I still do not eat this　Red soba
It would be probably very delicious.
Ideal for space food.!!

This is a little church in Mount Faro at Galicia - Spain. It´s a beautiful sky even though luminic pollution, maybe because is a high mount.

You can observe center of the milky way, and at left Andromeda and meteor (perseid).
