RUNNING MOON

DESCRIPTION
27,32 days. This is the time that, at a speed of 3.683 km/h, our moon uses to complete the orbit of 2,200,000 km around the earth. A telescope pointed on our satellite for 1 hour and 30 minutes and 100 shots to capture the lunar movement compared to the stars of the Milky Way in the background. Now at the last quarter, the Moon shows both the dazzling scythe that we are used to see, both the temporary 'dark side' visible thanks to the long exposure.

Reflection Nebula in the Earth's atmosphere

What does this image suggest to me?
Why can we detect reflection nebulas surrounding stars like the pleiades? This storm in the Sierra Nevada mountains, southern Spain, is in my opinion a good analogy to understand the process.The clouds of this storm do not emit light by themselves and they remain dark most of the time. But when a large amount of light is generated inside it, suddenly the entire structure of the water vapour in the atmosphere becomes visible. A clear difference from this analogy is that the light of the stars are much more constant and lasting in time than the instant light of a lightning strike.
Technical data:

Very beautiful. Fantastic lightning display. I suppose that the blue color seen in the clouds was real, or at least it was what your photographic equipment detected?

Thank you so much. You are correct Ann. The raw shots have a color very similar to the final result. In edition I streched a little bit the histogram, a bit of curves, crop and noise reduction.

A 78h collaborative image of NGC 7000 !
Full version : https://cdn.astrobin.com/thumbs/DqQvW1d ... hqkGbg.jpg

"Astropotes" (which means "astro-buddies" in French) is a collaborative astrophoto group created in June 2019.

The principle is simple: each membre can share its own raw files on the same objects, chosen by the majority of the members, in order to cumulate long exposure time and to produce deeper collaborative images.

We chose to start our collaboration with an image of a nebula and an image of a galaxy, in order to define the potential of our pre-processing and processing workflow on these two types of objects.

We are pleased to present you our first achievement on a classical object :NGC 7000, with a global integration time of 77h40 !

Raw files : Frédéric Girard, Nicolas Kizillian, Valentin Cohas, Baptiste Zloch, K-mille Colomb, Jean Baptiste Auroux & Thomas Lelu.
SII : 17h45, Ha : 36h30, OIII : 19h, R : 1h40, V : 1h40, B : 1h05.

Preprocessing : Matthieu Tequi & Mathieu Guinot
