Active region 2080 (upper part of image) was one week old when this image was taken and it featured a complex magnetic field that earlier had yielded multiple flares. Just south of region 2080 is newly formed region 2085 that was growing rapidly. The image is a L-RGB composite in H-alpha light where the L-channel comes from a 6" refractor while the RGB is an image made using a special tri-band technique (http://astromikael.blogspot.dk/2012/09/ ... art-1.html) with a 70mm refractor.
Setup: 6" refractor with Daystar H-alpha filter and USB3 video camera. Piggybacking this I had a 70mm refractor with a Coronado H-alpha filter and a Skynyx 2-2M USB2 camera. Two laptops and a Tak EM200 mount completed this crazy setup. The 6" produces high resolution images at the H-alpha wavelength while the 70mm makes lower resolution images which can quickly by detuned from the H-alpha line. Such detuning enables me to make a tri-band color image which can then be used to colorize the high resolution view. Check my setup out here: http://www.leif.org/mikael/solarsetup2014.jpg
Acquisition - 6" Daystar: best 60 out of 1800 frames shot over 70 seconds. Exposure time was 5msec with 26 frames pr. second.
Acquisition - 70mm Coronado: best 60 out of ~500 frames from three sequences shot over 3 x 20 seconds with zero, medium, maximum detuning from the H-alpha line.
An area of dark dust forms a shape that remarkably looks like a Wolf. A colourful area of the sky with emission nebula and sparkling stars of various hues.
Taken at a dark site. 16 hours of data total and this image is about 8 hours of from that data that was higher quality.
Hi
Here is a narrow band image of NGC7000 and IC5070 that I finished after starting it two months ago. It is 24x10 minutes Ha, 21x10 minutes OIII and 23x10 minutes SII.

Since a young age I have had the desire to take a trip through the southwestern of the United States, see and feel the shocking nature reflected in the Grand Canyon, in the Arches National Park and in the terrible atmosphere of Death Valley.
Finally, now in retirement, that wish came true and behind the wheel of my car, carrying some cameras to capture multiples landscapes, to show different characteristics from the nature of our planet.
I drove just over 7,000 miles in 32 days and I visited all these extraordinary places, most of them are under management of the National Park Service. I believe that nature, humanity and society, have found support and positive, creative, respectful and viable response from the National Park Service of the United States of America.
In some scenes you can see the atmospheric luminescence and in the evening in the Nation Monument anticrepusclares rays could be.
Hopefully it will be of your interest and I appreciate that you see the images and read these lines.
This area of dark nebula in the constellation of Scorpius strongly resembles a Wolf.
Taken at my dark site observatory with a TEC180 fluorite refractor.

Its simply amazing what is hidden in our own Milky Way Galaxy.

In the last few nights I was able to catch more data of M16. I got much better Ha data (better seeing) and also some OIII and SII data, that I had to stretch quite far). In the end I'm happy with the result (it's at only 20 degrees elevation here...).
Celestial Fireworks. The Milky Way appears to erupt from the top of a mountain. Below the mountain lies the ruins of the ghost town of Independence, Colorado founded and named by the discovery of the Independence lode on Independence Day, 1879. Above the town looms the mountain that appears to spew celestial fireworks, named Independence Mountain. The mountain is located at Independence Pass which located on the continental divide of the United States.
All of this in a photo taken on Independence Day. Hard to find a image with much more Independence than this one.

"Milkyway over Mt. Evans Meyer-Womble Observatory in Denver, Colorado"
Here is a 12-photo panoramic showing the Milky Way arching over the Meyer-Womble Observatory on Mt. Evans 37 miles west of Denver, Colorado. The observatory sits at an elevation of 14,193 ft and is owned and operated by the University of Denver. It is the 3rd highest optical/infrared observatory in the world.

Hi APOD! Hi Owlice! I finally have an unusual pic for you, after all your great ones that have given me so much pleasure... What do you think? Actually, I'm not sure if I uploaded that right, it seems complicated! If I have less than 10 posts, please can you override the spambot guard for me so I can put it on straight from my computer? I think I get that. Thanks!
Steve

Here she is... We saw it yesterday at sunset, there was another small one, which I've seen more often but this is more of a midair rainbow... Beautiful.
Note: I have a serious camera/ equipment deficiency at present that is being addressed, but in the meantime, my apologies for the low quality of the shot.

This may be a better shot. I took them at 18.45hrs from Petersfield, Hants, UK, with a sony DSC-T200.
