How to Take Star Photos Without a Telescope

 

You don’t need a telescope to take beautiful and even dramatic photos of the stars and the night sky. You just need a camera and film. In this article I give you tips and techniques for taking great night sky pictures.

There are two basic types of star photos you can take. The first type is a fast picture with an exposure of less than 30 seconds. This type of picture shows the stars as stationary. The second type of picture you can take is a star trail picture. If you leave the shutter of your camera open for an extended period of time the stars will form long tracks on the picture as they cross the sky. Both types are attractive and easy to do.  In addition to simply taking pictures of the sky you can add landscape features into the picture. This tends to make the picture very dramatic and especially appealing.

The Equipment you need

·         A camera that has the ability to leave the shutter open for long periods of time. This function is often called the bulb function.  The camera should have either a B or a T setting.  This can be difficult to find with newer digital cameras.

·         A roll of high speed film – 800 speed film is good but if you don’t have easy access to this film then 400 speed film will work reasonably well

·         A camera tripod or some other means of keeping your camera very still

·         A baseball hat or a piece of heavy dark cloth

How to take the pictures

1.       Before you go out load your film into the camera and take one indoor picture. This sets the film properly so the developer can see the frames

2.       Bring all your equipment outdoors for at least a half hour before you intend to take the pictures. This allows the optics of the camera to adjust to any temperature or humidity difference

3.       Set your camera firmly into your tripod

4.       Hold the baseball hat or piece of heavy dark cloth over the lens of the camera without touching the camera

5.       Activate the shutter button so the shutter opens

6.       The camera is now live and the film is ready to be exposed

7.       Remove the hat or cloth and this begins the exposure

8.       Count off how long you want the exposure to be – A good place to start would be with a ten second exposure

9.       Replace the hat or cloth so the lens is once again blocked

10.   Close the shutter by releasing the shutter button

That is the whole process of taking a night sky picture.  We use the baseball hat because activating the shutter will cause vibration in the camera which could distort the delicate picture you are taking.  Just the motion of you pressing the button or the motion of the shutter moving can be enough to ruin the picture and take away the pinpoint sharpness of the stars.

You might be wondering how to keep the shutter open without holding the button down. You can use one of a few different solutions. The first solution is something called a shutter cable release. This is a cable that connects to the shutter button of the camera. (Newer cameras might not have this option) You press the button on the end of the cable and then lock it in the shutter open position. The second solution is to use a rubber band or some other type of setup to actually hold your shutter button down.  I have used a rubber band successfully on a basic 35mm camera.

About the Exposure lengths

You should take a notebook with you and keep track of the exposure time for each picture you snap. This way you can judge which exposures worked the best and when you try again on another night your pictures will be improved.  Remember to start out by taking a picture of a household object so the first picture on the frame will be correctly set for the developer. Then take your night sky photos with different time intervals starting at 5 seconds. Then progress to some 30 second shots and 1 minute shots. 

Depending on what part of the sky you are taking photos of once you get over 30 seconds the stars will start to leave trails on the film. You can take exposures of several hours to get really long and attractive star trails. A minimum of about 20 minutes will leave a detectable and attractive trail.

Improving your Star pictures

To get the best pictures try to get the darkest skies possible. Light pollution from houses, streetlights and other city sources can wash out your picture. Also you can add earth bound objects to the picture. Silhouettes of buildings trees or other land based objects under a starry sky can make a very attractive picture.  If you have a nearby object that you want in the picture but it is too dark you can even shine a flashlight on it while the film is being exposed. This will illuminate the object with a soft glow but not ruin the picture.

When bringing your film to the developer make sure you tell them that you have taken night time star photos and that all the pictures should be developed and printed.  As a minimum you should make a note of this on the envelope you put the film in. It will avoid the developer thinking none of the pictures came out and not making any prints.

Astrophotography is the art of taking pictures of night sky objects and there are lots of possibilities for you to experiment in this art without a telescope. All you need is a simple 35mm camera, some high speed film and a few hours under dark skies.

A NICMOS parallel survey for galaxies at z = 7–10. $49.99 The epoch at z > 7 is thought to be important in the formation of the first galaxies, but the requirement of sensitive, wide-area near-infrared observations makes discovery of these sources difficult. This dissertation presents two surveys for z > 7 galaxies, using parallel imaging with the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) on the Hubble Space Telescope. In this way, we have efficiently accrued significant areas with sensitivities that can not be achieved from the ground. First, we carried out a serendipitous survey in J110 and H160 to search for galaxies at z ∼ 9. This survey consists of 135 arcmin 2 of imaging in 228 independent sight lines, reaching typical 5sigma sensitivities of J110 and H 160 ≳ 25 (AB). Fourteen J-dropout Lyman break galaxy (LBG) candidates are selected with J110- H160 ≥ 2.5, and the likelihood that any are genuine z ∼ 9 galaxies is considered. We find that if L*z=9.5 is significantly brighter than L*z=6 =6 as measured by Bouwens et al. (2006, 2007; a factor of four), then a few J-dropout LBGs are likely to be detected in our survey. Distinguishing these candidates from dust-reddened star-forming galaxies at z ∼ 2 — 3 requires followup observations. Longer wavelength followup observations of five J110 -H160 selected dropouts, using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope, shows that four of the five targets are certainly low redshift interlopers. Remarkably, though, one source has the spectral energy distribution (SED) of a z ∼ 9 LBG, with an apparent Balmer break between 3.6 and 4.5mum. The high redshift of this galaxy would imply that the luminous end of the rest-frame UV luminosity function has not evolved substantially from z ∼ 9 to z ∼ 3. However, more recent followup i' observations show a weak detection, strongly suggesting that the galaxy is an interloper. While our observations have shown that none of these five targets are viable z ∼ 9

AT BOOK WIDEFIELD ASTROPHOTOGRAPHY H $29.95 Wide-field astrophotography is an area where the beginner can bypass the complexities of prime focus telescopic astrophotography yet still excel and achieve good results quickly. Exquisite prime focus close-ups of galaxies and faint nebulae are attractive showpieces, but the art and technicalities of photographing such objects through a telescope are intimidating to the beginner. In high-resolution telescopic photography, the cost of the specialized equipment, the complexities of focusing fine, often invisible detail through the telescope, and guiding with extreme accuracy to achieve worthy results are obstacles to a novice sky shooter. Simpler non-telescopic wide-field astrophotography is an alternative that anyone who owns a camera can enjoy. Today, may well be the Golden Age of Astrophotography. At no time in the past has there been a wider range of films, both color and black and white, that do well when exposed to the night sky. Many of these films capture images in a few minutes that just a few years ago required lengthy exposure by an experienced astrophotographer. Some of these films can be processed in a 1-hr labgone is theera of waiting days to see your results. This text then introduces techniques needed to mount ordinary 35-mm and medium format cameras atop an equatorially-driven telescope in order to produce stunning portraits of constellations, the Milky Way, bright nebulae, and star clusters using wide-angle and telephoto lenses. Separate chapters extensively discuss cameras, lenses, filters, and photographic accessories suitable for astrophotography as well as the guiding techniques needed to accurately track moving celestial targets. Additional chapters also detail powerful astrographs such as the Schmidt camera, and describe a number of homebuilt devices which can enhance the convenience and versatility of wide-field astrophotography. Further chapters discuss the characteristics of photographic film, how to test a film for its suitability f

AT INTRO TO WEBCAM ASTROPHOTGRAPHY H $34.95 In the last few years webcam astrophotography has exploded onto the astronomy scene. It has rapidly evolved from short exposure six-bit black-and-white imagery into long-exposure full-color 16-bit per channel imagery of such qualitythat it rivals conventional means of astrophotography. Indeed, webcams have become the method of choice for planetary imaging. The message of this book is that you too can participate in this revolution without spending very much money. You do not need to invest $10,000 in a CCD camera, telescope and software. A basic webcam costs about the same as a so-so eyepiece. Software to control the camera and process the images that will get you going is free. If you have the telescope (practically any telescope that will track) and a computer you are ready. Since you see your results instantly the learning curve is much shorter. Regardless of how you apply a webcam to astrophotography, you will derive a number of benefits. Working with them has been accurately described as interesting, challenging, and fulfilling. Webcams are capable of producing beautiful astrophotos that create a lasting record of your astronomical experience. The book will guide you into this fascinating topic and allow you tobecome a participant in this latest wave of astrophotography progress. About the Author: Nearly 50 years ago Robert Reeves began his astrophotography adventure with his parent’s Voightlander 120-format camera. His first exposure from his south-Texasgarage roof was the brightest object in the sky, which turned out to be Jupiter. Unlike today’s readily available books and accessories that make astrophotography more user friendly, back then the budding enthusiast was left to his or her own devices. Robert was not deterred and found a lifelong avocation of imaging the universe with his camera. His images have been published in the leading astronomy magazines and books and in 2000 he wrote the highly acclaimed book Wide-Field Astrophotography followed i

Excerpt: Afocal photography , also called afocal imaging or afocal projection is a method of photography where the camera with its lens attached is mounted over the eyepiece of another image forming system such as a optical telescope or microscope, with the camera lens taking the place of the human eye .Overview Afocal photography works with any system that can produce a virtual image of parallel light, for example telescopes and microscopes . Afocal photographic setups work because the imaging devices eyepiece produces collimated light and the camera’s lens can focused at infinity, so they are both afocal systems , there is no net convergence or divergence in the light path between the two devices. In this system the device is focused on the object and the camera is placed above the eyepiece as close as possible. The draw back is the system will have a high focal ratio , with a correspondingly dim image, and some vignetting . A high focal ratio also means the field of view will be narrow. Field of view can be calculated using:Focal field of view /angle of view :Approximate:Precise:Film afocal photography Historically afocal photography with 35 mm SLR or large format film cameras is a very difficult method of photography. With film cameras the bulk and mechanical shake has to be taken into consideration, with some setups employing a separate tripod for the camera (adding the complexity of setting up the camera in relationship to the eyepiece). The general difficulties of focus and exposure with film cameras, along with the detailed mathematical

Astrophysics in the Extreme Ultraviolet $189 From the beginning of Space Astronomy, the Extreme Ultraviolet band of the spectrum (roughly defined as the decade in energy from 90-900 C) was deemed to be the unobservable ultraviolet’. Pioneering results from an EUV telescope on the Apollo-Soyuz Mission in 1975 forcibly demonstrated that this view was incorrect; but it required the all-sky surveys of the English Wide-Field Camera and the Extreme Ultraviolet Explorer to demonstrate the broad potential of this field. Over 700 EUV sources have now been detected. Over 150 researchers from 16 countries gathered to share results in this new field at the International Astronomical Union Colloquium No. 152. Papers were presented on a wide variety of topics including cool star coronae, white dwarf atmospheres and evolution, neutron stars, the Io torus, cataclysmic variable stars, active galactic nuclei, the interstellar medium, winds and atmospheres of early type stars, and EUV plasma diagnostics. Selected manuscripts from this meeting are provided in these Conference Proceedings.

BOWER 500F/8 LENS W/CS SKY/ND2/ND4 FLTR $119.89 The Bower 500mm f/8.0 Manual Focus Lens is a catadioptric mirror T-mount lens, precision manufactured in South Korea.When combined with the T-mount to fit your camera system, this mirror lens mounts to camera and works on both full frame cameras as well as the APS-C style digital SLR cameras. T-Mounts are available for all the digital SLR systems, as well as for C-mount systems. However, in every case the fixed f/8 aperture is not communicated to the camera body. As such, you can use the lens in M manual exposure mode or A aperture-priority mode only.Despite this lens’ long 500mm focal length, it has a compact 3 x 3.5 size and weighs under 1 pound, making it a bit easier to handle than normal 500mm refractor lenses (it should be used with a tripod or monopod in any case). It also has a much different rendering of out of focus areas than a normal lens; highlights will be doughnut-shaped rings with more saturation and contrast on the edge of the ring than on the center.This lens is an ideal candidate for astrophotography use when mounted to a Vixen GP2 Photo Guider (or other motorized equatorial telescope mount).

BOWER T-MOUNT 500 F/8 PRESET TELE LENS $119.99 The Bower 500mm f/8 Manual Focus Lens is a classic refractor-style T-mount lens, with an aperture diaphragm in the middle of the lens body to stop down the aperture when necessary. However, it is assumed that much of the shooting with such a lens will be at its maximum f/8.0 aperture, with a tripod, monopod, or other such support.When combined with the T-mount to fit your camera system, this super telephoto works on both full frame cameras as well as the APS-C style digital SLR cameras. T-Mounts are available for all the digital SLR systems and even for C-mount systems. However, in every case the aperture is not communicated to the camera body. As such, you can use the lens in M manual exposure mode or A aperture-priority mode only.This lens’ sophisticated achromatic refractor design yields images with pleasing peak contrast and well controlled flare. It can be used at maximum aperture on a very bright day for some images of moving subjects.This lens can also be used as a handheld telescope by adding Lumicon’s LA1070 adapter along with a 1.25 45?/60?/90? diagonal and any 1.25 eyepiece, or for astrophotography by using on an SLR mounted to a Vixen GP2 Photo Guider or other motorized equatorial telescope mount.

Auszug: The Karl-Schwarzschild-Observatorium (Karl Schwarzschild Observatory) is an astronomical observatory owned and operated by the institute of Thüringer Landessternwarte (Thuringian State Observatory) ‘Karl Schwarzschild’ Tautenburg. In 1992 it was acquired by the state of Thuringia.
