DIGITAL CAMERA Instruction Manual TG2 Thank you for purchasing an Olympus digital camera. Before you start to use your new camera, please read these instructions. Digital Camera for Astrophotography Get StartedNothing is permanent except change, said the Greek philosopher Heraclitus. Anyone who follows the rapidly evolving digital imaging world has to agree. Consumer level digital cameras are becoming ever more powerful, small if you want, and cheap. They have replaced film cameras as the tool of choice for the snapshooting public. But what quality photographs will your digital camera for astrophotography produceDigital Camera for Astrophotography vs. Film. Film still surpasses all but the highest end digital cameras for resolution and color accuracy. Photography in general is easy right You pick up your camera, point it in the direction of what interests you, and depress the shutter button. However, there are. And, unlike dedicated astronomical CCD cameras that use cooled chips, the sensors in consumer cameras generate objectionable noise during long exposures, so their useful exposure times are generally limited to a matter of seconds. This is fine for bright subjects such as the Moon and planets, but too short for the deep sky though you can beat the problem by taking many short exposures and digitally stacking them.

Digital cameras generally need a computer to manipulate and print images, but the technology is evolving rapidly, and photo printers that work without a computer are now mass market items. Advantages of Going Digital. Of course, the advantages of going digital are many. You get instant results and can adjust what you do accordingly no waiting for pictures to come back from the photo lab. You can shoot all you want and throw all but the best pictures away without worrying about film and processing costs. The cameras memory can probably hold many more images than a roll of film. Since the cameras output is already digital, the images are ready for computer processing with programs such as Adobe Photoshop, which can correct color imbalances, optimize brightness levels, dynamic range, contrast, and color saturation, and enhance image quality by stacking exposures. You can create a wide field mosaic by stitching together adjoining frames. The images are Internet ready you can e mail them or share them on the Web. They can be easier to sort and organize and take up less storage space than photo albums or shoeboxes. Digital cameras are versatile they can be used to digitize prints and 3. They can also be coupled a spotting scope for wildlife photography. The price of high resolution cameras is constantly dropping. All these features make a digital camera for astrophotography very attractive for astro imaging. If you already have one, you should certainly see what it can do. The Afocal Method. A basic, consumer level digital camera for astrophotography doesnt have removable lenses you have to go to a more expensive digital SLR camera for that. Download Digital Sky 2 Manual' title='Download Digital Sky 2 Manual' />Creating astrophotography with a digital camera in this method means only way to shoot through a telescope with them is by the afocal method, whereby the cameras lens is aimed directly into the telescopes eyepiece. You can hold the camera by hand, mount it on a separate tripod, or make or buy a bracket to attach the camera directly to the telescope. See our afocal method to learn more about its history. Like the old eyepiece projection technique, the afocal method dramatically increases the image size at the expense of a much slower effective fratio or photographic speed. You may also get some vignetting and image distortion. Vignetting is the darkening of an images edges that happens when light is cut off by mechanical limitations. It typically happens when the camera is held too far from the eyepiece or when the apparent angular field of the cameras view exceeds that of the eyepiece. This, however, is usually not a problem when you are photographing planets or other small objects that can be kept centered. To reduce vignetting, set the camera as close to and centered on the eyepiece as possible. Also, choose an eyepiece with ample eye relief some short focus eyepieces have such limited eye relief that a camera cannot get close enough to image well through them. Find the best camera position by experimentation. Improving Your Images and Experience. Zooming in narrows the camera for astrophotographys angular field and thus can minimize or eliminate vignetting but avoid using digital zoom, which sacrifices s resolution. Zooming also increases magnification, which often makes focusing easier. On the other hand, it makes finding your target tougher. Image distortion can occur due to various effects in the eyepiece and camera optics. The center of the image may be in focus while the outer areas are not, severely restricting the usable field. Be sure you keep the cameras image plane centered on and perpendicular to the telescopes optical axis. Also, keep the eyepiece and camera lenses free from smudges and dust, which degrade contrast. Mounting the camera on a separate tripod can prevent vibration while avoiding the need to rebalance the telescope for the cameras weight. With such an arrangement, it helps to orient the eyepiece so that it moves directly toward or away from the camera as the telescope follows its subject across the sky. Use a black cloth or cardboard mask to shield the eyepiece and camera lens from stray light. Although not essential, a telescope motor drive is convenient since it keeps the subject centered in the camera fpr astrophotographys frame as you focus and compose the shot. For scopes without a drive, you can still take good pictures if you keep exposures short. Position your subject at the edge of your frame opposite the direction of drift, then wait for the object to glide near the frames center before triggering the shutter. Focusing Your Camera for Astrophotography. As with film astrophotography, you need to obtain perfect focus, since any errors will show up prominently. You can begin by focusing the telescope visually using the eyepiece if you use prescription glasses, wear them and setting the camera lens to infinity. If the camera for astrophotography doesnt have a manual override, just use its autofocus mode. The built in LCD screen can be used for centering and focusing, but some people find it a bit too small and coarse to judge the focus precisely. If your camera has a video output, you can connect it to a larger monitor say a 1. TV to help you adjust the fine focus while watching the TV screen. This real time video display is also useful when good seeing is intermittent you can use the video to judge the best time to take the images. Imaging the Sun through the telescope requires a proper, safe solar filter click here for a list of filter vendors. Be sure to cover the front of the cameras viewfinder. Focusing with the LCD screen in bright daylight can be tricky, so shade the screen or use an external, shaded TV monitor. Some people attach a loupe to the LCD screen with rubber bands or Velcro for added accuracy when focusing and to assist in viewing the screen in bright daylight. As with film astrophotography, a good quality finder is helpful for aiming the telescope. A larger, higher power guidescope, if precisely aligned with the main scope, can help in getting small targets such as planets into the cameras view. Taking the Shot. Unlike single lens reflex SLR cameras, digital point and shoots have no mirror slap that can cause vibration when taking a picture. But you can still cause shaking when pressing the shutter. To prevent this, use the cameras self timer or wireless remote release if it has one.
