The Milky Way gets high in the sky in the early part of the night in July, so we have a lot of the bright region around the galactic center to include in compositions.
To cover thousands of dollars in deposits and fees for 2017, many of my workshops have an early enrollment sale until February 28: www.jeffsullivanphotography.com/blog/bodie-night-photogra....

11mm f/5.6
This is an experiment using my Tokina 11-16mm which is designed for an APS-C sensor, but used on my new full-frame Nikon D750.
Lots of skyglow from Santa Fe, but on a more cosmic scale, you can see Orion, Taurus, the Pleiades, Comet Lovejoy (just below the Pleiades), the double cluster in Perseus, and the Andromeda galaxy. Pus some more stuff if you look closer (eg, M33).
LDN 1251 is a dark star forming region in the constellation of Cepheus. It lies approximately 1,000 light years away from Earth. This dark cloud obscures newborn stars shown in the reddish regions of the image. There are also some distant galaxies just visible behind some of the lighter dusty regions.
Taken last year at Los Coloraos, just before my camera decided to break down and needed returning the manufacturers for repair. This created a big gap in my plans for summer and winter imaging but it’s back now and fully functional. This is also known as the Rotten Fish Nebula, but I prefer the alternative name Anglerfish Nebula.

Thank you for viewing!
We decided that this location was one of our favorites for the year, despite the constant traffic in and out of the popular touristy area the reflections off the lake were incredible and the interesting lighting created by the headlights made for a very cool foreground. This is a lesson in how to make a pretty tall mountain range look very very small, the sky up here is HUGE and the prominence of the Milky Way tends to put large things in a small perspective. That night we had a good Aurora event and the airglow/skyglow colors were fantastic due to the increased solar activity. All in all this is a wonderful location to take pictures from and a night I won't ever forget.
15 exposures for this image all shot with a Nikon Z7 and Sigma Art 40mm on a Sky Watcher Star Adventurer Mini tracking mount. 9 sky exposures were 2 minutes at ISO 800 and f2, 3 foreground exposures were 1.5 minutes at ISO 1600 and f1.4, and 3 reflection exposures at 30 seconds, ISO 10000, and f2.
By switching off its floodlights and the streetlighting within its grounds, Guildford Cathedral has become a remarkably dark urban site which makes it pretty good for gazing at the wonders of the night sky. I've added a location so you can view its position relative to housing, trunk routes, the university campus and the town centre. The top of the tower just catches some ambient glow, whilst the rest of the lighting was provided by a low, nearly-full moon. Check out this comparison from a previous visit showing the change in conditions triggered by switching off the surrounding lights.
If you want to try a similar type of shot using a long exposure to capture startrails, I just updated my tutorial for stacking which is being featured in the latest edition of Photography Masterclass magazine for iPad- available > here < in the App Store.

Because it's fall! The direction and orientation of the Milky Way changes every month, and by fall it crosses Min Street in Bodie, offering unique compositions in September and October that aren't available when we're in town in May through August.
This was at 9:24 pm, so the Milky Way still had time to move west (right) before we leave at midnight. It's fully dark in Bodie by around 7:45 pm in mid-October, so these are our nights with the most dark sky shooting hours in the park.
In 2017 we have room in our October 13 and 14 sessions.

For all the astrophotographers and night sky enthusiasts out there I suggest you check out Bea Gallardo-Lacourt’s new paper “On the Origin of STEVE: Particle Precipitation or Ionospheric Skyglow?”. So we now know that while Steve accompanies an aurora, it is not actually formed by the same mechanism of particles raining down into the ionosphere. The paper suggests that Steve is an entirely new phenomenon distinct from typical auroras, as the POES-17 satellite detected no charged particles impacting with the ionosphere during the Steve event which was studied. This means that is likely produced by an entirely different yet unknown mechanism they call “skyglow”. The skyglow is somehow related to the band of fast-moving ions and super-hot electrons passing through the ionosphere right where Steve was observed. I took this shot of Steve over Circle Lake in Eskers Provincial Park. It was a very dark night so you can see some skyglow in the sky along with some green from the Aurora Borealis in the North to the right of frame. Northern British Columbia, Canada. Love Life, Love Photography .
Two nights and 13 1/2 hours of exposure...For a Messier object it took a bit of time to do it justice. Not sure I succeeded here, but I gave it my best shot (puns intended).

A 180° panorama from the first of the Vermilion Lakes, on October 2, 2016. The view is looking east, at left, to the Banff townsite and Mount Rundle, and to the south, at centre, toward Sulphur Mountain, and to the southwest, at right, toward the Milky Way over the Sundance Range. Light pollution from Banff lights the sky at left, while green bands of natural airglow colour the sky right of centre.
This is a panorama of 6 segments, with the Sigma 20mm lens at f/2.2 for 20 seconds each, with the Nikon D750 at ISO 6400.
Milky Way and Andromeda with my Sky-Watcher Esprit 80mm and Radian Raptor telescopes. Taken in bortle 1-2 area north of Ash Fork, AZ. There a touch of northern lights, and skyglow. Single Exposure, 20sec, Canon 6DM2 14mm, f4.5 ISO 10,000
A panorama of the arc of the Northern Lights across the northern sky at right, from home in southern Alberta on November 21, 2019. At far left is the summer Milky Way setting while in between is the urban glow from cities to the west (notably Calgary) with the skyglow now blue-white from LEDs lights — it used to be yellow from sodium vapour lights. So this is a study in sky glows, both natural and artificial.
The Big Dipper and Polaris are at centre over my house.. Capella in Auriga, Aldebaran and the Pleiades in Taurus, and the stars of Perseus are at right rising in the northeast. Altair and Aquila are at far left, setting in the southwest.
This is a 6-segment panorama with the 15mm Venus Optics lens at f/2 on the Sony a7III for 20 seconds each at ISO 1600, stitched with ACR.

A 150° panorama of an arc of diffuse aurora to the northeast, and above the glow of solstice twilight to the north at centre, while the urban sky glow from Calgary lights the sky at left to the west, as well as an odd band of cloud that persisted all evening across the north.
This was at the Old Barn site near home.
The aurora has the characteristic green band but with a magenta glow above from high altitude oxygen glowing.
Capella is embedded in the auroral arc, just right of the road which is aimed due north. The W of Cassiopeia is at right, with the Andromeda Galaxy rising below in the northeast, along with the stars of Perseus and Pegasus. Arcturus is at far left over the barn in the west.
This is a crop from an 8-segment panorama with the 24mm Sigma lens and Nikon D750, all segments 30 secconds at f/2 and ISO 800. Stitched with Photoshop Photomerge. ACR refused to stitch the left segments.
Here is an early evening view of the Hyades and Pleiades star clusters in the constellation Taurus.

I was absolutely cream crackered on Friday Night (27th September) and was in two minds whether to go out or not, whilst in the back of my mind remembering that it rains a whole lot in Scotland. Then I noticed that Aurora was kicking off; so decided to head out. I was treated to this in a small, remote Glen in Perthshire...I was the only observer to this particular little scene. Now that's a reason to go out and stargaze right there, isn't it?

Steven's Tree and Star Circle (19 exposures, 8 minutes each ISO 100 so a total of 2 hours and 32 minutes). First exposure was at 10:53 pm, the last at 1:18 am. Long exposure noise reduction OFF. f/4, 23mm.
NOTE: I have reprocessed this image and I like the (son of ) Bristlecone Pine Star Circle a bit better. See what you think.
If you're itching to do this kind of photography yourself, please visit Star Circle Academy.
To get this shot, I set up before sunset with a programmable timer (intervalometer) delayed 4.5 hours - so it started exposing at 10:53 PM. Moon set was at 11:55 so most of the exposures included moon glow - either direct illumination or skyglow.
After pressing the "start" button I drove back to Grandview Campground and went to sleep. These things are hard work :-) I got up at 3:00 am to go fetch the camera. It managed about 21 images before the battery gave out. I was hoping for about 4 hours worth. It was about 33 degrees Farenheit. The upside to the cold temperature is that it helped to keep the camera noise very low..
I used Digital Photo Professional (comes with the Canon DSLR cameras) to export 19 images as JPG files with little or no adjustments. I then used the excellent freeware program "startrails" by Achim Schaller to stack (combine) the images. This program takes the brightest pixel from each image and includes that pixel in the final image. Since the sky is very dark, the brightest spot on each shot is usually a star. Photoshop CS4 Extended has a "statistics" tool with "Maximum" that does something similar. Startrails.exe, however, is much easier and much faster than Photoshop for this purpose. Startrails also includes a "dark frame" feature to help set the black level and reduce noise.
After combining all of the images and producing a single TIFF file, I sharpened it and did some contrast improvements using Picasa3 - another free and quite powerful program. The primary enhancement was to increase the highlights and to slightly increase the shadows. This action alone brought out the color in the stars (and YES, stars do shine in red, yellow, orange, blue, and white). I'm sure I also adjusted the white balance slightly to "warm" the photo. My final action was to clone out the few odd bits of noise that remained. I used Picasa3's "retouch" feature for this.
This photo was taken during an outing of the Bay Area Photography and Exploration Society which I led. More details about my star trail photography technique are available via my Star Circle Academy BLOG or in my Short Treatise on Night Photography.
You may also find my timelapse treatment of this photo interesting and very short.

This is a framing of the rich complex of nebulosity in and around the constellation of Cygnus, in a blend of "white light" images and images shot through a deep red hydrogen-alpha filter that isolates the red emission line from the gas clouds, bringing them out in much more detail than is otherwise possible.
The North America Nebula (NGC 7000) and adjacent Pelican Nebula (IC 5070) are at upper left beside blue Deneb. The Veil Nebula, a supernova remnant, and catalogued as NGC 6995 and NGC 6960 for the main arcs, is at lower left. The Gamma Cygni complex, IC 1318, is at centre. However, the field is littered with other faint arcs and patches of emission nebulosity. The dark area below Deneb is the Northern Coal Sack. The bright area at lower right in the Milky Way is the Cygnus Starcloud, a region less obscured by dark interstellar dust. The "beak" star of Cygnus, Albireo, is at lower right, so the framing takes in most of Cygnus and all of the Northern Cross asterism.
This is a blend of: a stack of 20 x 5-minute exposures at f/2 and ISO 3200 with the Canon Ra equipped with a clip-in Asrtronomik 12nm H-alpha filter, plus a stack of 25 x 2-minute exposures at f/2.8 and ISO 1600, with the latter shot through a front-mounted URTH broadband filter to help block skyglow and gradients. All with the Canon RF 28-70mm lens at 70mm and on the Star Adventurer tracker for tracked but unguided shots taken from home October 1, 2022 on a very clear and mild night for a total of 150 minutes of exposure. The initial H-alpha shots were taken with the waxing crecent Moon still up.
All stacking, alignment and blending in Photoshop. Luminosity masks applied with Lumenzia. The H-alpha stack was layered in with a Screen blend mode and with its own adjustment layers and masks, and colorized with a Hue-Saturation layer. The H-alpha data was not added by replacing the red channel, as that provides no control of the blend of the H-alpha image. A mild and masked Orton Glow effect added with Luminar AI.

En-route from Somerset to home we caught a beautiful Winter sunset at one of my all time favourite landmarks-the Low Lighthouse, at Burnham on Sea, built in 1832. This was my passing shot before leaving, and it was quite dark by then so that the wooden lighthouse was totally silhouetted against the sky. I'll post a less dark image sometime!
It gave the chance to test drive my new lens. Zeiss Milvus 21mm and Manfrotto geared head 405. Pleased with both so far.
Burnham is close the Bristol Channel, which has the second highest tidal range in the world of 15 metres (49 ft), second only to Bay of Fundy in Eastern Canada. The constantly shifting sands have always been a significant risk to shipping in the area.
