Thanks. I felt like I was shooting IN a mosh pit with all the bodies coming over the barriers and having to dodge all of the security and 4 or 5 other photographers up there at the stage with me.

Flip side of Salty's photo. Uploaded to Facebook, then downloaded to my computer, then uploaded to Photobucket. Quality may have suffered but my HD crash last fall leaves me little choice \:\|

nice. i'm planning to make a trip out to the middle of no where this summer to try and get the milky way.

this is a popular shot i'd like to try and recreate.

Gorgeous! How do they get the stars so crisp?

In my two attempts at shooting the night sky I've been frustrated by star trails, even when shooting wide open (f/2.8) and at a high ISO. I can't imagine everyone is using star tracking hardware and then making a composite with the foreground...so what am I missing I wonder? Maybe they take a darker sky in camera and then make it pop in post?

some people stack images. i have seen some really good crisp stars out of a "claimed" single exposure however

from one of his images

 Quote:
'NightScape'' series style: If I only wanted to capture the stars against a totally black sky and have no landscape features in the foreground, I'd just attach my camera and lens to an astronomy type tracking motor, and expose as long as I wanted (using low ISOs). However, doing this would blur the landscape features, because camera would be following the stars and the rotation of the earth! My goal in this series is to show the stars in a relationship to an earthly landscape feature, and not just do astrophotography.

In my style of "NightScape" photography, I am trying to capture the stars as points of light, not star trails, so my exposure must be very short -- usually less than 30 seconds. This requires very fast and expensive lenses and extremely high ISOs. (The Canon EOS 5D Mark II and Mark III are some of the best cameras out there for producing a minimum amount of noise at these high ISOs.)

TECHNICAL STUFF
Camera and Lens: This photo was taken with my 15mm full-frame Canon fisheye lens (30 seconds @ f2.8, ISO 6400). This lens gives me almost a 180-degree angle of view. Many of my photos are taken with the Canon 24mm f1.4 lens (84-degree angle view). I would roughly calculate that the full-frame sensor of my Canon EOS 5D Mark II is about 40 times more sensitive to light than a typical point-n-shoot camera, and several times more sensitive than your eye, when coupled with a 15 to 30-second time exposure. Each exposure is 30 seconds or less (any longer than this, then the stars appear to move or streak, due to the rotation of the earth -- producing star trails or arcs, rather than round dots). Please note that most DSLR cameras with a "fast" prime lens can capture my style of NightScapes.

Fast Lenses: The aperture (or "F" stop) is usually set as near to wide open as the lens design will allow, in order to capture as much light as I can during the exposure time. Prime lenses (not zoom lenses), with large apertures (f2.8, f2.0, or f1.4) are preferred for this type of photography, although I've seen some great images with slower, f3.5 lenses.

High ISOs: Most of my star photos are are taken at ISO 3200, 6400, or 8000. With these high ISOs and fast lenses, the camera is able to see detail that your eye and other cameras cannot. Cameras like mine and Nikon's D3 can go even higher (12800, 25600, 51200, and 102400 ISO), but there is always a trade-off in quality. At the moment, I have chosen not to go above 8000, until I can find technology that will obtain the quality I desire. Some DSLR cameras do not go above ISO 1600. I have seen some exposures with these cameras at that ISO, using an f3.5 lens that look great -- the night skies are a little darker than the ones I shoot (eliminating the fainter stars), but the views are still stunning.

Digital Noise: High ISO's and long exposures (anything over 1-second) can produce digital noise -- what film users call "grain" or graininess. Many cameras (especially point-n-shoot cameras) cannot go above ISO 1600 -- and even their 1600 has more noise (digital graininess) than my 6400. Some have been critical of the noise; however, the noise I'm getting at ISO 6400 right now is less than what film gave me at ISO 800, 10 years ago. It is also much less than what I was getting only 6 years ago at ISO 1600 with any digital camera. Technology has come a long way, and I'm very grateful for all the improvements. It allows me to see what my naked eye cannot! Still, anytime I can lower my ISO to 3200 or 1600, I try to do so, in order to reduce noise. This can be done by "stacking" several under-exposures (taken at ISO 1600), and processing them into one photo, with a brighter exposure.

Narrow window of opportunity: The big problem in doing star photography is finding a totally dark and cloudless sky: It must be at least 2 hours after sunset, at least 2 hours before sunrise; and the moon must have set (because it washes out the stars). A New moon or a less than 8% crescent is acceptable. I rely a lot on moon tables from the Farmer's Almanac. As you can tell, there is only a narrow window to shoot these kind of photos, and it only happens a few days each month (when you add the weather factor).

Light pollution: Oh, and did I mention you must be at least 75 miles from the lights of a large town? There are getting to be fewer of these places on the earth. Some of the glow in the sky, right around the tree line, is from the town of Jackson, WY (population of about 9,000), which is about 20 miles away.

Longer focal length lenses require shorter exposure times: With my 180-degree, full frame fisheye lens I can expose as long as 30 seconds and keep the stars as points (unless the image is enlarge over 12 x 18, upon which the stars appear a little elliptical). A 24mm (84-degree angle coverage) requires that I shorten my exposure to 19 seconds or less. A normal 50mm lenses (45-degree angle coverage) requires a 9 seconds or less exposure! This is because the longer focal length lenses are enlarging the area of the sky you see and magnifying the earth's movement -- requiring even shorter exposure times. Some astro-photographers use the "600 rule" for determining the length of their exposure time: dividing 600 by the focal length of the lens (using a full-frame 35mm equivalent). I adjust this to my own "450 rule", which produces less blurring on larger prints. Thus, the maximum exposure time for a 28mm lens would be 16 seconds (450 / 28 = 16).

Lens technical problems: The bigger my lens' aperture, the shorter I can expose my images, and the lower I can set my ISO. One of my favorite large-aperture lenses is the Canon EF 24mm f1.4L II. However, "big" aperture lenses cost a premium, and I've found that unless I stop down at least one aperture stop or more, the coma (spherical aberration) at the edge of my images is terrible -- the starry points of light grow ghostly wings and take the shape of an obtuse triangle. I am constantly fighting a choice between getting more light to the camera's sensor (by opening up the aperture) or whether I should have better quality (less aberrations) near the edges of my images!

Yep. And it's hard to believe they have nothing for a Mac that'll stack. Lame.

I don't even know what high pass is lol.

Some of the edges are out of focus because i forgot my tripod so i took it from a rock. Not quite sure why it didn't focus, f11

my sole attempt at night sky photography, up in Idyllwild on Thanksgiving. Was on my in-law's back porch. Some smoke from the fireplace looks like a galactic cluster. A huge reason for buying my Tacoma recently was to go camping and shoot the sky. Looking forward to that.

I love taking night shots man, the biggest thing around here that sucks is the light pollution. I've gotta drive at least 45mins north before I can get some decent shots. When I'm way up north fishing, it's pretty much perfect.

That is great! I love that. I'm a sucker for night shots too. One of the first accessories I bought for my A65 was an intervelometer.

Thanks! It's just far enough from the city I guess that you can see some nice sky. It's only about two hours outside of downtown LA. Wouldn't see any milky way I'd bet but there's not a whole lot around the mountain.

This was from the same spot, just an hour earlier, looking over Hemet.

And about an hour before that, hiking around with my dog. There was a locals mountain bike trail we followed for awhile. Real narrow, real fun. Soft soil, shady, lots of good turns. Have got to get my bike up there.

It's close enough to tomorrow, so I'll put this up now. One of the p52 assignments had to do with baseball, my little league coaches son is coaching HIS son's team now, so I called him up and used him for the assignment then came out to shoot some of a game for him too as thanks. Was pretty fun actually, and I had a crazy high percentage of perfect timing on hits and catches and stuff, I guess being familiar with the subject really does pay off, I played ball for ~10 years I think.

nice baseball pic Chef. I'm shooting my son's baseball team, but it's sooooooo boring... my son's team can hit pretty well and field decently enough, but the other teams they play against are not that good, at all.... I'm hoping to get back out and shoot some more GWU baseball soon. I've missed quite a few games so far since I've been busy with stuff...
