The Astrophotographers Winter Wonderland

Image by skypointer

At this time of the year, many nightscapers pack away their cameras and say that the Milky Way season is over. They couldn’t be more wrong! The core season might be over, but the winter Milky Way is visible all night and makes an excellent photographic target.

With its abundance in hydrogen emission nebulas, the "bad side" of the Milky Way is actually more colorful than its brighter summer counterpart, especially when captured with an astro-modified camera.

Orion is a real gem: The sword is dominated by the famous Orion Nebula and the nearby Running Man Nebula. Both are glowing in red Hydrogen and blue Oxygen light. Orion’s belt harbors the Horsehead Nebula, a dark dust cloud that is silhouetted against another deep red nebulosity (IC 434) and right next to it, the bright Flame Nebula shares the same field of view.

This whole complex is surrounded by the elusive Barnard’s Loop an interstellar gas cloud that is ionized by the stars inside the Orion Nebula.

Another prominent part of the Orion’s nebulosity, is a ring around Lambda Orionis (Meissa). It measures about 12 degrees across and probably is the remains of a supernova explosion, now ionized by the ultraviolet radiation from Meissa itself and some of the surrounding hot stars.

Those blessed with dark skies might even be able to record the very elusive Witch Head Nebula, an extremely faint reflection nebula, believed to be an ancient supernova remnant or gas cloud, illuminated by the nearby supergiant star Rigel.

Of course there is not only Orion. Other prominent Hydrogen emission Nebulas are the Rosette Nebula in the constellation Monoceros, the Seagull Nebula near Canis Major, the California Nebula in Perseus, Cassiopeia’s Heart and Soul Nebulas or The Elephant Trunk Nebula in Cepheus.

The whole winter Milky Way is dotted with open star clusters. Some are naked eye objects like the Pleiades, the Hyades, the Beehive Cluster or the Double Cluster and many of them are part of the famous Messier Catalogue (e.g. M34 – M38, M44 –M48, M67). Some of these open clusters are surrounded by gas clouds and the ionizing radiation from their stars powers many of the emission nebulas mentioned above.

Furthermore, autumn and winter is galaxy time. Our galactic neighbor, the Andromeda Galaxy, is the most prominent example, but there are many more, like the Triangulum Galaxy (M33), pictured here to the east of Andromeda.

Fed up with deep sky objects? Then you might like this: Under dark skies you might be able to observe the gegenschein. The backscatter of sunlight by interplanetary dust causes this optical phenomenon. It forms a slightly more luminous, oval glow directly opposite the Sun within the band of the luminous zodiacal light. The intensity of the gegenschein is relatively enhanced, because each dust particle is seen in full phase.

Even closer to home, you might be able to see meteors (from the Leonids or the Alpha Monocerotids in November or the famous Geminids in December) burning up in earth’s atmosphere and of course you might also be able to capture some colorful airglow.

  Northwestern Cygnus, 8 panel mosaic (HaOIIIRGB)   Image by   Nico Carver   This region of Cygnus west of Deneb is anchored by the bright and colorful stars 30 and 31 Cygni. There are many types of interesting and overlapping nebulae in this region including many HII regions catalogued by Dickel, Wendker, and Bieritz, as well as more recent discoveries such as the giant supernova remnant known as G 82.2+5.3 and the much smaller possible planetary nebula PN PM 1-320. This was my most challenging photo yet with more than 46 hours of integration, and the time-consuming process of creating a seamless 8 panel mosaic.

My latest processing and imagery captured from grand mesa observatory using the Sky-Watcher Esprit 150mm ED F7.0 Triplet APO Refractor that Sky-Watcher USA have sent to us for testing. The camera is the QHY168 Monochrome CMOS camera (beta test model) with an APS-C format sensor. The QHY168M matched with the Sky-Watcher 150 Esprit has an image scale of 0.94 arcsec/pixel and a Field of view of 51.6 x 77.7 arcmin. Using Optolong 7nm H-Alpha, 6.5nm SII and OIII filters the data was preprocessed using Pixinsight and post processed in Photoshop by mapping the SII, Ha and OIII data respectively to the R, G and B channels to create a Hubble Palette (SHO) rendering.Total Integration time: 14 hours The setup and data that I used is from October’s subscription on “System 2” and one of 3 telescopes currently available through Grand Mesa Observatory’s Subscription services, if you want to sign up go here: grandmesaobservatory.com/equipment-rentals/ Technical Details:Image capture detailsTerry Hancock downunderobservatory.comLocation: GrandMesaObservatory.com Purdy Mesa, Colorado Dates: October 2018H-Alpha 280 min, 28 x 600 sec, bin 1x1OIII 310 min, 31 x 600 sec, bin 1x1SII 250 min, 25 x 600 sec, bin 1x1Camera: QHY168M Monochrome CMOS APS-C BetaGain 10, Offset 30, Calibrated with Flat, Dark & BiasOptics: Sky-Watcher Esprit 150mm ED Triplet APO RefractorFilters by OptolongImage Acquisition software Maxim DL5Pre Processed in PixinsightPost Processed in Photoshop At the center of IC1805 lies the open cluster of stars known as Melotte 15 contains stars that are almost 50 times the volume of our Sun.

Whereas the Orion Nebula generates enough light to be visible to the unaided eye, the Horsehead has a far lower surface brightness and presents a challenge to visual observers even with large telescopes. But it’s a delight for astrophotographers and arm chair stargazers.The Horsehead complex lies just south of the brilliant blue supergiant star Alnitak, the easternmost star in Orion’s Belt and just north of the Orion Nebula. The glowing reddish-pink region in the background is cataloged by astronomers as IC 434. Like the Orion Nebula, IC 434 is an emission nebula. It’s powered by the blazing-hot star Sigma Orionis, just south of Alnitak. Much of the nebula is permeated by tenuous streaks caused by magnetic fields in the region.
