Boo! Here’s a great shot of the Witch Head nebula, so named because it resembles the profile of a wicked witch. This nebula’s ‘official’ name is IC 2118, and it is just a cloud of interstellar gas and dust — nothing to be afraid of! The eerie shape is sculpted in part by radiation from the supergiant star Rigel, the brightest star of Orion. In fact, Rigel illuminates the nebula by reflecting off the dust grains, making it glow. Inside the nebula, young stars are being born. This image was taken by a former NASA scientist/engineer Fred Herrmann of the Owl Mountain Observatory near Huntsville, Alabama — ftherrmann2012 on Flickr. You can see an infrared image of this same nebula taken by the WISE spacecraft.

Astrophotographers were out in full force this weekend to try and capture the bonanza of comets now visible in the early morning skies! You’ll need a good-sized telescope to see these comets for yourself, however, but with the Moon now waning means darker skies and better observing conditions. Above is an absolutely gorgeous image of Comet ISON taken by Damian Peach. See below for more images of not only Comet ISON, but also Comet Encke, Comet Lovejoy and Comet LINEAR — now in outburst.
In fact, one of our “regular” contributors, John Chumack, captured all four comets in one morning, on Saturday October 26!
Four comets captured in one morning! Clockwise from top left: Comet ISON 2012 S1; Lovejoy C/2103 R1;, 2P ENCKE, Linear 2012 X1. Credit and copyright: John Chumack/Galactic Images.
Here’s what John said about his Comet ISON image: “The tail extends off the frame it is at least 20 arc minutes long now and the coma is still around 3-4 arc minutes in diameter. The comet is looking good at about 12th magnitude and continues to slowly brighten, just 30 more days to perihelion — closest point to the Sun. Hopefully it puts on a good show for all of December too!”
And Comet Linear 2012 X1 was at 14th magnitude, but now in outburst, John said, “it is over 100-fold brighter at 8th magnitude and expanding! It was low on the horizon at dawn, and tough to get. It just cleared the trees at 7:07am in bright dawn light! I managed a couple of quick shots before my CCD was flooded completely with light!”
Of Comet Lovejoy, John said, “I found it has developed a faint long tail…it is at least 12 arc minutes in length and the comet’s coma is now around 6 arc minutes in diameter. I already notified Terry Lovejoy in Australia and he was excited to hear his comet has developed a new tail!”
Here’s a timelapse video from John of Comet Lovejoy moving through the constellation of Canus Minor:
Here’s a view from a smaller telescope from Tom Wildoner, to give a better idea of what “most of us” would see with our humbler telescopes!

Even NASA astronomers were out trying to take images of these comets. Here’s an image taken from NASA’s Marshall Spaceflight Center:

NASA explains the image:
In the early morning of Oct. 25 (6:45 a.m. EDT), NASA’s Marshall Space Flight Center in Huntsville, Ala., used a 14″ telescope to capture this image of Comet C/2012 S1 (ISON), which is brightening as it approaches the sun. The comet shines with a faint green color just to the left of center. The diagonal streak right of center was caused by the Italian SkyMed-2 satellite passing though the field of view. At magnitude 8.5, the comet is still too faint for the unaided eye or small binoculars, but it’s an easy target in a small telescope.
At this time of this image, ISON was located in the constellation of Leo the Lion, some 132 million miles from Earth and heading in toward the sun at 87,900 miles per hour.

This beautiful new view of Comet ISON comes from a collaborative effort between astrophotographers Cliff Spohn in Ohio and Terry Hancock in Michigan, taken on October 21, 2013. “The first time in almost two weeks that we have had a break in the clouds and rain we could not miss this rare opportunity to capture ISON using Cliff’s equipment,” said Terry via email. “Credit goes to Cliff for capturing the object while I did the calibration, stacking in CCDStack post processing in CS5 and video editing.”
You can see a timelapse video below, covering 93 minutes of imaging, again on October 21. It’s obvious ISON is still intact and it continues to bright, as it is currently about magnitude 9.

Update: This new one is just in from astrophotographer Damian Peach, and its a beauty! Taken on October 24.

From John Chumack: “I just had to try just a telephoto on Comet ISON while it was near Mars,” John said via email. This view shows Comet ISON (C/2012 S1) near Mars and Regulus, the brightest star in the constellation Leo. This image was taken on October 18, 2013 from
Warrenton, Virginia at 6:27am EST looking over Washington D.C.
Triple conjunction of Comet ISON, Mars, Regulus on October 14, 2013, as seen from Payson, Arizona, USA. Credit and copyright: Chris Schur.
This nice image comes from Chris Schur from Arizona, taken on October 14, and is also of the conjunction. “As you may recall, on this date of 10/14 the three objects were in a perfect line going from south to north in Leo,” Chris said via email. “What a spectacular sight in the 11 x 80 binoculars! While the comet was quite faint, a short 1/4 degree of tail could be seen, and the gorgeous blue and orange colors of the planets.”
Chris used a Canon Xti, ASA800 with 10 minutes total integration time, with a 80mm f/4.8 Ziess APO refractor on a Televue GEM. Taken from Payson, Arizona at 5,100 feet elevation.
The orbital paths of the International Space Station and the Cygnus capsule overlap in this 20 second exposure taken from Bannister Green, England on October 22, 2013. Credit and copyright: Wendy Clark.
Here’s a nice photo of the trails in the sky from the International Space Station and Orbital Science’s Cygnus freighter. This was captured just a few hours after Cygnus was undocked from the station on October 22, 2013. Astrophotographer Wendy Clark says to “please ignore my garden spaceship to the right,” but sorry, having a model of the starship Enterprise in your yard is just too wonderful to ignore!
This is a 20 sec exposure at ISO 1600 f4.5, 18mm, taken at 19.25 BST. The brightened spot is a flare (sun-glint) from one of the spacecraft.
And about an hour ago from this posting, Orbital Sciences confirmed that the Cygnus had deorbited:
We have lost the signal from #Cygnus. Reentry accomplished. Represents the official completion of our COTS program with @NASA partners
Cygnus’ mission elapsed time (launch through deorbit) was 35 days 3 hours 18 minutes 27 seconds
Here’s another great photo of the two spacecraft together in the sky from Germany by Wolfgang Dzieran:

He explains what you are seeing in the photo: “The long, light line is the track in the middle is the ISS. The second track, which runs almost parallel to the orbit of the ISS is the Cygnus supply module, and at one point becomes conspicuously bright. This bright illumination is called a flare,” Dzieran writes on his website. “At top right and bottom you can see the traces of two aircraft.
Thanks to both astrophotographers for sharing their images!

The Bubble Nebula, also known as NGC 7635, seen in the Hubble Palette. Credit and copyright: Terry Hancock.
Here’s a beautiful look at the Bubble Nebula, taken by astrophotographer Terry Hancock using what’s known as the “Hubble Palette,” — imaging in very narrow wavelengths of light using various filters. This allows very subtle details to be revealed, things that the human eye cannot see. Terry has been working on this one for a while — since mid-August — but the results are spectacular!
Terry took images from his “DownUnder Observatory” in Fremont, Michigan. He explains the image and techniques he used:
This last capture over 10 nights took me since mid-August 2013 to complete due to very high moisture in our West Michigan Skies right through this shoot. So, the data is therefore noisy and not the best but it is time to call it done for this year and move on! Due to poor conditions I had to use the H-Alpha data I had from my RGB+HA version using the QHY11 and combine with only one night capture using the QHY9 with it’s 3nm H-Alpha filter.
Using narrow band filters and post processed using the Hubble Palette technique the SII filter is assigned to Red, SII is assigned to Green and OIII is assigned to blue channel.
Total exposure time was 26 hours — persistence pays off! Thanks to Terry for sharing his gorgeous image!

How fun is this?! “Here’s a panoramic image from the aurora on October 14,” wrote Swedish astrophotographer Göran Strand. “I’ve made a small world trapped inside a bubble floating in space. And a lonely photographer is trying to capture the ongoing aurora with his camera.”
Uranus, imaged from Italy on October 3, 2013, when the planet was at opposition. Credit and copyright: Giuseppe Petricca.
Last week, we asked if you were looking for an observing challenge: looking for planet Uranus when it reached opposition — where it is opposite the Sun the sky, meaning the planet rises as the Sun sets. Giuseppe Petricca from Italy took the challenge and ran with it. His skies over Sulmona, Abruzzo in Italy cleared, and not even 12 hours after the official time of opposition he got this shot using his new Toucam Pro II on a Newtonian 200/1000 on EQ5 unmotorized mount.
Nice!

Aurorae dance across the sky and among the clouds over Norway on September 28, 2013. Credit and copyright: Frank Olsen.
Frank Olsen reports that the weather in arctic part of Norway has been fantastic lately. Even so, the aurora are starting to make nightly appearances.
“I was standing on the very tip of an island in Vesterålen with a spectacular view, looking out on the Atlantic ocean,” he said. “With the full moon behind me, the clouds were amazing.”
Clouds mixed in with the aurora made for some lovely views. In all, Frank said he nabbed almost 400 images on his memory card! See another shot, below.

As we’ve said previously, these gorgeous sights must be payback for enduring the long winters in northern Norway. You can see more of Frank’s beautiful imagery of aurora, the night sky and more at his Flickr page, his website (he has prints for sale) or his Facebook page.
