Central region of the lactea via and its predominance of hydrogen

In this image we have two points to be mentioned:
1) Made with Camera Modify (by removing the Ir CUt Filter and placing Baader Filter, increasing the bandwidth [improving H-alpha uptake)
2) Used a narrowband filter (Dual Narrouband composed of H-alpha and OIII)

H-alpha is related to hydrogen capture. Light is created by the hydrogen atom, the main constituent of the universe and the basis of nuclear fusion that feeds the stars. H-alpha is red in part of the light spectrum and contributes to an overwhelming red color in most nebulae
Then we have by the two mentioned methods an extreme predominance in H-alpha uptake, showing in red in the central region of the milky way.

New Caledonia is only inhabited by 280 000 people for a 18 575km² superficy and almost half of them settled in the capital: Noumea. This image has been captured about thirty kilometers from this city, in a place where almost no artificial light exist... apart from the one the city brings. This shows how visible the light pollution can be, even from far away. With in mind the consequences on the flora, fauna and even ourselves, this is an issue we should address seriously in the upcoming years. The sky from this place is already a Bortle 2 scale.

In the top right of this image and located in Sagittarius, Barnards Galaxy or NGC 6822, is a barred irregular galaxy about 1.6 Million light years away. It is part of our local group of galaxies and relatively small at just 7000 light years diameter. It has prominent HII and OIII emission nebulae and although often not revealed in images, NGC 6822 also sits behind an extensive foreground field of very faint Milky Way cirrus dust. The strange ghostly "P" shaped feature in the lower left of the image, is Sharpless 63, which is much closer to us at about 700 light years and is part of the extensive molecular cloud MBM 159.

"The Greatest Perseids Show"



As you can see in the photo, The Perseids fly over the sky with the presence of Mars, Saturn and Jupiter. Also, you can see the highest mountain in the European Union, the always magnificent Mont Blanc.
Surrounded by two glaciers that converge a bit further down, you can see both of them in the image, the Mer de Glace which flows for a total distance of 12 kilometres, covering an area of 32 square kilometres in the central third of the Mont Blanc massif. On the left-hand side, you can spot the Leschaux Glacier and its hut (the light just next to the glacier).
In addition, if you take a deeper look, just below the Grandes Jorasses mountain range you will be able to see climbers trying to summit the mountain with the first lights (you can see their headlamps).

The photo had to be taken really early after the twilight as Mars was about to hide behind the Grandes Jorasses and Jupiter was also about to also disappear under the mountain range.
As always, we were gifted with a spectacular perseids show at almost 3000m high.

Abell 383 - Gravitational lenses

The giant galaxy cluster in the centre of this image contains so much dark matter mass that its gravity bends the light of more distant objects. This means that for very distant galaxies in the background, the cluster’s gravitational field acts as a sort of magnifying glass, bending and concentrating the distant object’s light towards Hubble.

Abell 665 - Abell's highest richness class of 5

Abell 665 is a galaxy cluster in the Abell catalogue in the constellation Ursa Major. It is also known as the only cluster in his 1989 catalog to receive Abell's highest richness class of 5. This means that it contains at least 300 galaxies in the magnituderange of m3 to m3+2, where m3 is the magnitude of the third-brightest member of the cluster. The clusters in all other richness classes contain less than 300 such galaxies. Abell 665's combination of high brightness and large distance, made it an excellent candidate along with 37 other clusters to help determine the Hubble constant using the Sunyaev–Zel'dovich effect in 2006.
