Saturn and four of its major moons Mimas, Dione, Tethys and Enceladus on September 9th, 23:48ut.

Hi, this "omega" Moon was taken from me on Sept 6th, 2017 from Monopoli -Apulia (italy)- with my 500mm lens and SLR camera Canon Eos 600D.

I hope it's interesting

The Soap Bubble Nebula in Cygnus

Copyright Scott Rosen. Website: http://www.astronomersdoitinthedark.com/


High Resolution Version

Although it officially has the the rather ignominious name of PN G75.5+1.7, the Soap Bubble Nebula is nonetheless a beautiful example of a planetary nebula. These type of nebulae are formed when stars are in their later stages. During the red giant phase of a star's life, the strong stellar winds will blow off shells of gas. Ultraviolet radiation from the star's core heats up these shells and ionizes the gases, primarily Oxygen. We see this superheated shell as the planetary nebula. In the case of the Soap Bubble Nebula, this shell forms a nearly perfect sphere.

The Soap Bubble Nebula is extremely faint, which explains why it wasn't discovered until recently. The nebula is located in a very commonly photographed portion of Cygnus, just 2/3 of a degree from the very popular target, the Crescent Nebula. Nevertheless, the Soap Bubble Nebula wasn't discovered until 2008. As it happens, it was discovered by amateur astrophotographers (Dave Jurasevich, Mel Helm, and Keith Quattrocchi).

The Soap Bubble Nebula is believed to be located about 4,000 light years away from us. It's angular size of only 4 arcminutes translates to a diameter of about 5 light years.

NGC 1097

It’s a fantastic galaxy to look at. It certainly has a lot going on. Visually, you can see the distortions and tidal debris that have resulted by the interaction with the companion galaxy NGC 1097A. Personally, the most interesting thing are the optical jets that show up in deep exposures.

Here is a simple animation showing the interaction of the Jets and the Ha regions along the arms.

A beautiful scene unfolds over the coast of Iceland. This was the first time I truly saw the aurora with my own eyes. Though I was awestruck, I was fortunately able to get the camera rolling also. Please view the static and especially the animated full sized images !! Static:

This is a view of a small church that stands on the top of a hill few kilometers from the city of Kavala,Greece. I have wanted to do a milky way shot here since last year but by the time I tried it was too late in the summer and the galactic center had already moved too far south to get it in the frame

Synthetic LRGB image of SN2017eaw
Copyright: Stephen Armen This color image of active supernova SN2017eaw in the galaxy NGC6946 was mapped from the Johnson-Cousins BVRI filter set to LRGB. NGC6946 is known as the fireworks galaxy due to the large number of supernovae in the past 100 years (>8).

The image is fairly low resolution due to being captured with 2x2 binning for increased sensitivity and shorter exposure times.

The image was assembled from one night of observing with SDSU's 1 Meter telescope on Mt. Laguna.
The observers were graduate students at SDSU, I only processed the image.

Saturn, Moons Enceladus, Tethys on September 15th, 00:23ut. Within eight hours from its real-time science transmission and within twelve hours before its control crash insertion to the surface Cassini spacecraft.
