Colourful Moon
Are the colours real? well yes, but they are not as saturated in reality.
With the dark-side added in to give the image more depth and a 3D look.

NUBECULA MINOR

Irregular galaxy NGC 292 (The Small Magellanic Cloud or SMC) lies about 200,000 light years away in the southern constellation of Tucana. It is the smaller of the Milky Way's two satellite galaxies.

The brightest object within the SMC is the stellar nursery N66, which looks like a mini version of the Tarantula Nebula in the Large Magellanic Cloud. Within the heart of this large H II region is the open cluster NGC 346.

There are two magnificent globular clusters in this image: the 4th-magnitude NGC 104 (47 Tucanae) and the 7th-magnitude NGC 362. Both clusters are actually within our own galaxy and are not associated with the Cloud.

In order to capture the complete SMC, I created this 6-pane mosaic from images obtained remotely using iTelescope T12 at the Siding Spring Observatory in New South Wales, Australia.

To compensate for over-exposure in certain main features, I also used iTelescope T31 (Planewave 20" CDK), T27 (Planewave 27" CDK) and T33 (ASA 16" Fast Newtonian Astrograph) to capture some additional, higher-resolution data to include in the mosaic.

The total imaging time, through HaLRGB filters, was 161 minutes.

The way to the Alps

Credits: Adrien Mauduit

After an epic Xmas time with my family and friends, I wanted to share a very wintery picture taken three nights ago as I climbed the Station Monts Jura.
I've always wanted that shot showing the beauties of the winter milky way rising above the Alps with this magnificent view. There were three major hurdles that night though: the 24% moon was setting to the west and it was drowning deep-sky objects in the moonlight, hence the little contrast in the milky way and the bleu hue given to the whole picture. Then the unforgiving light pollution coming from Geneva and its surroundings did not help either. On top of that, occasional haze and airglow caused patches of different brightnesses and colors on the picture. However (and that is going to be the point of my tutorial), you can still take a gorgeous picture under these very challenging conditions, showing a lot of details. It was a very technical shots, because I used a tracker (Vixen Polarie) and a light pollution filter (Pure Night), but the picture consists of:
FOREGROUND: 1 row of 3 single landscape pictures at 50mm, f/2.8, ISO 1600, 40''
BACKGROUND: 3 rows of 3x3 stacked landscape pictures at 50mm, f/2.8, ISO 1600, 40''
Canon 6D Baader modded + Sigma 50mm Art f/1.4. So this blended stacked panorama had the exact same settings, date, time, place, orientation, lenses, camera...
It's a shame that you won't be able to zoom in on Facebook, but this very high quality 80 MegaPixel panorama shows excellent details when you zoom in on it thanks to the successive 50mm frames put back to back. From top to bottom, you can mainly see: Perseus, the California nebula, The Pleiades, Capella (and Auriga), the Flaming Star nebula, Gemini, Messier 35, NGC 2175 (Jellyfish nebula as well) the Hyades (Taurus), Orion (and all its nebulae), the Rosette nebula, the Christmas Tree Cluster, Procyon rising in the bottom left corner (Canis minor). You can also see me at an orientation table showing all the major mountains of the Alpine ridge. It is actually one of Europes most renowned and gorgeous vistas over the Alps (the highest peak to the right is Mont Blanc culminating at 4810m).

NGC 247 is an intermediate spiral Galaxy located in the constellation Cetus. It is a member of the sculptor group and is located approximately 11.1 million light years away. The most striking feature of this Galaxy, the void, contain stars that are different from those around. They are older, redder and colour, and much fainter. This suggests that the star formation within the void has been arrested. It is believed that star formation slowed a billion years ago. We are still unsure how the void has formed. Recent studies suggest it might have been caused by gravitational interactions with another galaxy, or even a recent interaction with a nearly dark subhalo that collided with the disc.

The centre of the Galaxy is visible as a bright whitish patch surrounded by mixture of stars, gas, and dust. Silhouetted against the background of stars the dust and gas has formed interesting filaments.

The best month for viewing NGC 247 is in November when it is at its highest altitude. It has an apparent magnitude of 9.9, and an apparent size of 21'.4 × 6'.9. NGC247 is also known as ESO 540-22, C 62, IRAS 00446-2101, MCG -4-3-5, PGC 2758, UGCA 11.
