Thor's Helmet (NGC 2359) is a complex structure comprising a wind-blown bubble surrounding the Wolf-Rayet star WR7 (HD 56925) in Canis Major and wing-like appendages that emanate radially from it. Although its distance is uncertain, at the adopted distance of 11,960 lys (some estimates are twice this value), the bubble spans roughly 16 lys and the displayed field is 80.1 lys (W) x 78.7 lys (H) in extent.The central bubble comprises mostly interstellar material that has been swept up by the fast wind streaming from this 16 solar mass star. Interactions with a nearby molecular cloud mask the bubble’s outer regions to the southeast (north is up, east is to the left), and additional involvement with the interstellar medium are apparent in the reddish-colored ionization fronts on the edges of the radial features. Recent research based on the high 26Al/27Al and low 60Fe/56Fe ratios inferred for the early solar nebula suggests that triggered star formation in the swept-up shell of an ancient Wolf Rayet bubble may have been responsible for the Sun’s birth.

The data used to prepare this picture were collected as unguided 1-min sub-exposures on several nights between 7 December 2016 and 3 April 2018 at the Burke-Gaffney Observatory in Halifax, NS by a robotic 0.61-m Planewave CDK24 reflector operating at f/6.5. The telescope was equipped with an Apogee CG-16M CCD camera and Astrodon Gen II (E-series) broadband (RGB) and narrowband (H-alpha and OIII) filters. Its output was binned 2x2 to provide a resolution of 0.94-arcsecs/binned pixel. The sub-exposures were integrated using CCDStack (CCDWare) to produce mean background-flattened images of 1.60, 2.03, 1.87, 3.97 and 3.73-hrs duration in the R, G, B, H-alpha and OIII bands, respectively. A preliminary color image prepared from the mean broadband results was used to produce color-balanced channel images and a synthetic Luminance frame.

Subsequently, Photoshop (Adobe) was employed to: (1) blend the mean H-alpha and OIII images with the high-pass filtered synthetic Luminance; (2) blend the mean H-alpha image with Red, OIII with Green, and OIII with Blue, and high-pass filter the results; (3) produce a new color image from the blended R, G, B frames, which was used to color the blended synthetic Luminance; (4) slightly adjust the shape of the stellar profiles to reduce distortions introduced by the lack of guiding; (5) noise filter the corrected synL(Ha,OIII)R(Ha)G(OIII)B(OIII) image; (6) enhance image contrast by applying a mild unsharp mask at small scales to the entire image followed by a slightly more aggressive mask at moderate scales to the bubble; and (7) selectively enhance the contrast of bright interfaces using Soft Light blending of a spatially-masked copy of the image with its full version.

NGC 4236 or Caldwell 3

Copyright: Mark Hanson

NGC 4236 (also known as Caldwell 3) is a barred spiral galaxy located in the constellation Draco. The galaxy is a member of the M81 Group, a group of galaxies located at a distance of approximately 11.7 million light years from Earth. The group also contains the spiral galaxy Messier 81 and the starburst galaxy Messier 82

Messier 16, Eagle Nebula or "Pillars of Creation"
Copyright: Mark Hanson, S. Mazlin, R. Parker ,W. Keller, T. Tse, P. Proulx, R. Vanderbei, M. Elvov; SSRO/PROMPT/CTIO

Messier 16 (M16), the famous Eagle Nebula, is a star-forming nebula with a young open star cluster located in the constellation Serpens.

The nebula is best known for the Pillars of Creation region, three large pillars of gas famously photographed by Hubble in 1995.

Also known as the Star Queen Nebula, M16 lies at a distance of 7,000 light years from Earth and has an apparent magnitude of 6.0. The cluster’s designation in the New General Catalogue is NGC 6611, while the nebula is referred to as IC 4703.

The name Eagle comes from the nebula’s shape, which is said to resemble an eagle with outstretched wings. American astronomer Robert Burnham, Jr. introduced the name Star Queen Nebula because the nebula’s central pillar reminded him of a silhouette of the Star Queen.

Antares and Rho Ophiuchi region

The Rho Ophiuchi cloud complex is a dark nebula of gas and dust that is located 1° south of the star ρ Ophiuchi of the constellation Ophiuchus. At an estimated distance of 131 ± 3 parsecs, this cloud is one of the closest star-forming regions to the Solar System.

Imagesh2 126 by Richard Sweeney, on Flickr

The Image above is Sh2-126. It's a very feint emission nebula in Lacerta. If you locate Andromeda and trace a line towards Deneb, it’s about half way. This is a large star forming region approx. 1200 light years from Earth. The source of its ionisation is the intense ultraviolet radiation of the star 10 Lacertae, a blue main sequence star.

It was shot over 7 nights in September 2017. 12 hrs Ha in 150 second exposures, 7 hrs luminance 150 sec exposures, 11 hrs rgb again 150 second exposures.

I used a Samyang 135mm f/2 lens with a Zwo Asi 1600mm camera mounted on an AzEq6. Captured from my backyard in East Cork Ireland.

HELIGOLAND NIGHT SKY

Rare view on the Galactic Center above the rock of Heligoland (North Sea, Germany on April 17th 2018)
While being close to Germany's brightest lighthouse one has only 2 seconds of exposure time between the rotary lights.
This panoramic image was made out of nine 35mm shots with f/1.4 and Iso 16.000.
On the right rock in the foreground you can see some northern gannets resting. The image was taken close to the "Lummenfelsen", which is famous for its population of common murres.

The Antennae Galaxies

The Antennae Galaxies are one of the youngest examples of colliding galaxies, as well as one of the nearest pairs of interacting galaxies to Earth. They are located in the constellation of Corus around 45 million light years away.
NGC 4038 and NGC 4039 were two separate galaxies some 1.2 billion years ago. The larger was a spiral galaxy, NGC 4039. The smaller galaxy was a barred spiral, NGC 4038.

About 600 million years ago, NGC 4038 and NGC 4039 passed through each other. At some point, they would have resembled the Mice Galaxies. Around 300 million years ago, the Antennae’s stars began to be released from both galaxies. These gravitational interactions have resulted in the long tails forming an antenna shape. Within the tails or streamers, areas of starburst activity exist.

Perhaps in the future, when our galaxy the Milky Way and the Andromeda galaxies come together, they may look similar to the Antennae during at least one point of their gravitational interaction.
