NGC 1316 - lenticular galaxy in Fornax

Copyright: [url=mailto://info@irida-observatory.org]Velimir Popov, Emil Ivanov[/url]

NGC 1316 (also known as Fornax A) is a galaxy about 60 million light-years away in the constellation Fornax. It is the fourth-brightest radio source in the sky. NGC 1316 is located at the edge of the Fornax Cluster of galaxies. NGC 1316 appears to be interacting with NGC 1317, a small spiral galaxy to the north. However, that small spiral galaxy does not appear to be sufficiently large enough to cause the distortions seen in the structure of this galaxy. The galaxy NGC 1316 may be the site of a galaxy-merger in progress. The strange dusty lines could be caused by interactions with another galaxy over the past billion years.(Unusual Giant Galaxy NGC 1316).

NGC 6744 - A Sibling of the Milky Way in Pavo

Copyright: [url=mailto://info@irida-observatory.org]Velimir Popov, Emil Ivanov[/url]

NGC 6744 is a spiral galaxy about 30 million light-years away in the constellation Pavo. The NGC 6744 is one of the galaxies most similar to our Milky Way in the local universe. There is even a distorted companion galaxy — NGC 6744A, seen as a smudge to the upper right of NGC 6744, which is reminiscent of one of the Milky Way’s neighboring Magellanic Clouds. One difference between NGC 6744 and the Milky Way is their size. While our galaxy is roughly 100,000 light-years across, NGC 6744 is bigger with a disk stretching 175 000 light-years across.(Spiral Galaxy NGC 6744).

The Orion Molecular Cloud Complex

I've been working on shooting things at a larger scale to capture complete constellations. First with my work on my William Optics Star 71, and now with my Canon 100mm. Completed with a Gerd Neumann Filter Drawer system, I've been able to pair with with my ATIK 383 CCD camera. The scale is impressive. Here, I’ve framed the entire Orion Constellation in 9 panels with over 1280 individual light, dark, flat, and bias frames. This mosaic reveals the majestic Barnard Loop surrounding the belt stars, the Horsehead Nebula, the Witch Head Nebula, The Angelfish Nebula, and the Great Orion Nebula.

Integration:
Ha- 20- 300s x 9- 1x1
L - 10- 60s x 9- 2x2
R - 10- 60s x 9- 2x2
G - 10- 60s x 9- 2x2
B - 10- 60s x 9- 2x2
Matching dark frames
20 Flat Frames
20 Bias Frames

Equipment:

Software:
Capture in Sequence Generator Pro
Calibration in Pixinsight

Universal Nights: Glacier National Park Airglow and Milky Way

This image is a 4 panel mosaic of the Milky Way with green airglow in the night sky over Glacier National Park in Montana on May 22nd, 2015. Green airglow is an atmospheric phenomena that occurs when oxygen emits energy in the form of light after oxygen becomes excited by sunlight. A road overlooking this beautiful snow-capped mountain range and glacial lake made for a memorable scene to capture. My fellow astrophotographer friend David Lane can be seen down the small trail standing as mere tiny dot with his camera gear compared to the wide open landscape. Amazing how the lake water reflected the star light and airglow. For me, this is one of my favorite photos that I captured this past summer. Being out under the stars away from city lights opens up an entirely new world that I hope all humans can experience. If you ever are in Montana during summer, make sure to stop up at Glacier National Park and view the stars on a clear night. I used my Nikon D750 and 24mm lens set to ISO 5000 and F/1.4.

Thanks for looking,

NGC 5866 from Hubble Legacy Data. I post this image because after I processed the data from the Hubble Legacy Archive, I noticed some wispy dust lanes in the upper part of the galaxy that I hadn't noted on other versions of this object. I don't think it's a processing artifact. It's not very evident in the small hot linked image on this post, but here's a link to a larger image where it's pretty obvious. http://hwilson.zenfolio.com/img/s10/v10 ... 7526-6.jpg

Moon winter halo

A 22° halo is a type of optical phenomenon, forming a circle with a radius of approximately 22° around the Moon, as the moonlight is refracted on millions of randomly oriented hexagonal ice crystals suspended in the atmosphere.
