I started this on an unusually steady night on December 8th. Then it's been mostly cloudy since then.

I saw high cloud wisps during sundown on March 3rd and figured it would not be a clear night. It's very difficult to see high clouds at night.

I decided to start shooting at 8:30 PM to see what might happen. I was pleasantly surprised to find the air was super steady, even better than December 8th! I guess the high clouds dissipated and left a very steady situation up until 3:36 AM when clouds moved in again.

Hard to say when I might be able to add color and maybe more luminance given the mostly cloudy evenings this year in Southern California. But I figured I'd share what I have so far and what's possible on two super steady nights with an 8" SCT in 19.75 SQM skies.

The Night Sky over Monemvasia, Greece
The constellation of Cassiopeia (left), the Double Cluster in Perseus (left) and the Andromeda Galaxy (right) on a crystal clear night over the island of Monemvasia in Laconia, Greece. Monemvasia is a small rocky island off the east coast of Peloponnese. It was separated from the mainland by an earthquake in 375 AD.

Interesting picture! The muted colors give the Large Magellanic Cloud a new appearance. The yellowish hues bring out the old to intermediate populations, and we can see that they are widespread. The blue populations are bright, and we can see some prominent pink Hα nebulas, too. The Tarantula Nebula is so bright that it looks white. Fascinatingly, that large halo appears to consist mostly of old to intermediate stars.

Thanks! Your image shows the LMC in a new light!

Crescent Moon and Anglo-Australian Telescope

The Anglo-Australian Telescope (AAT, Siding Spring Observatory, NSW, Australia) is ready for another night observing with the SAMI (Sydney-AAO Multiobject Integral-field spectroscopy) instrument. A crescent Moon is seen towards the west through the opening of the dome.

Photo taken using a CANON EOS 5D Mark III, 0.6 seconds integration, 70mm lens at f2.8, 400 ISO. Thursday 2nd March 2017, 8pm AEST.

Milky way and Northern lights by Alfredo Madrigal, en Flickr

[English]
I present a panoramic photograph of the last week in Iceland. At the same time you can see the Winter Milky Way, several arcs of Aurora Borealis and Venus reflected in the most incredible glacial lagoon I have visited (Jökulsárlón). In the background we can see the mountains of Vatnajökull, forming the largest glacial in Europe in volume of ice and the second in extension. Another thing I love about photography is that we see several objects in the sky combined with the auroras, the California nebula, the Pleiades, the double cluster of Perseus, the North American nebula, and the Andromeda galaxy. The Boreal auroras have a power of color with all green and violets were of a certain intensity that night, around KP = 4-5. In the lower left corner we can observe my setup 2 making a timelapse and in the background, the top of a small mountain a photographer.

Les presento una fotografía panorámica de la semana pasada en Islandia. En ella se puede apreciar al mismo tiempo la Vía Láctea de invierno, varios arcos de Aurora Boreal y Venus reflejado en la laguna glacial más increíble que he visitado (Jökulsárlón). Al fondo podemos observar las montañas de Vatnajökull, formando el mayor glacial de Europa en volumen de hielo y el segundo en extensión. Otra cosa que me encanta de la fotografía es que vemos varios objetos del cielo combinados con las auroras, la nebulosa california, las pléyades, el doble cúmulo de Perseo, la nebulosa Norteamérica y la galaxia de Andrómeda. Las Auroras Boreales tienen una potencia de color con todos verdes y violetas fueron de cierta intensidad esa noche, alrededor de KP=4-5. En la esquina inferior izquierda podemos observar mi setup 2 haciendo un timelapse y al fondo, la cumbre de una pequeña montañita un fotógrafo.

Luckily March 6th was clear from 8 PM to 4 AM, so I captured 7 hours of RGB.

Molecular Cloud MBM 25 (Lynx)

More resolution 2500x2000 and acquisition data: : http://afesan.es/Deepspace/slides/MBM%2 ... nx%29.html

MBM 25 is a very diffuse molecular cloud that covers practically the whole image, extending in the constellation of the Lynx. These molecular clouds, also referred to as flow nebulae or galactic cirrus, are made up of gigantic dust and gas clouds of very low density (estimated to be between 25-50 particles per cubic centimeter), basically H and CO.

They belong to our own galaxy but are located in high latitudes galactic, that is, above and below the main disk or galactic plane of the Milky Way. They are at distances of the order of thousands or tens of thousands of light years, much closer that distant galaxies that glows in the background
(in this case, literally hundreds of them in the background) and whose vision and light filter us by getting in our visual. The dust disperses the blue light and reinforces a broad spectrum of red light, known effect known as "ERE "(Extended Red Emission). This sensibly attenuates blue glimpses and enhances the reds in visual images.

These structures were first detected in 1984 by the infrared IRAS satellite and later studied in depth by Magnani, Blitz and Mundy constituting the MBM catalog.

Description:

Located about 180,000 light-years away, in the constellation of Dorado The Tarantula Nebula, is part of the Great Magellanic Cloud, satellite galaxy of the Milky Way. It is a region of intense star formation, and has a diameter that exceeds 1000 light-years. The star cluster R136 in the center of the nebula produces much of the energy that makes the nebula visible. It is the largest known emission nebula. It is about 100 times as far away as the Great Orion Nebula, and if it were In the same distance that Orion is of us (1500 Light Years) would cover an area of 60 full moons, being able to cause shadows (Wikipedia) Initially it was considered a star, however in 1971 Nicolas Louis de Lacaille identified it like a nebula.
