B 11/10 Welcome to a new world of adventure. Your new StarShoot Solar System Video Eyepiece (SSVE) is capable of displaying detailed, full-color video of astronomical objects in our solar system. The planets, Moon, and Sun (with optional solar filter) can all be imaged to create spectacular views on your TV Screen. The SSVE can even be used during the day to take images of terrestrial subjects. You’ll find that this inexpensive, yet capable and easy to use camera will enhance all of your journeys with your telescope. Please read this instruction manual before attempting to use the camera. Parts list • StarShoot Video Eyepiece (SSVE) • 9V power adapter System requirements (refer to Figure 1) telescope The SSVE can be used with virtually any telescope that is compatible with 1.25" format eyepieces. The camera simply is inserted into a focuser in the same way as a standard eyepiece (Figure 1). If you use a star diagonal, you should remove it. If your telescope does not have enough inward focus travel, you will need to use an optional 1.25" Barlow lens to extend the telescope’s focal plane to the camera’s imaging plane. For most types of astro-imaging with the SSVE, using a telescope with a focal length of at least 1000mm is recommended. Otherwise, the image scale may be too small. To increase the effective focal length of your system, use a Barlow lens or other type of tele-extender lens. Mount While using an equatorial (EQ) mount is recommended to achieve the best results, one is not absolutely required for general imaging with the SSVE. Since the maximum exposure time is only a fraction of a second, astronomical objects will not drift significantly through a telescope attached to an altazimuth mount or Dobsonian base during single image captures. Use a sturdy mount that is appropriately sized for the telescope tube being used. Figure 1. To use the SSVE, a telescope, mount and viewing/recording device that accepts RCA composite input such as TV, Camcorder, DVR and VCR. For obtaining the best planetary images, however, we do recommend an equatorial mount. Planetary imaging requires combining many individual images, and having an equatorial mount will prevent the planet from drifting out of the field of view of the camera during the time it takes to acquire the large number of images necessary. A motor drive (single-axis) is recommended too, so you can track the target object as you transmit live images to your laptop or PC. Video can be recorded via standard VCR’s, DVR’s or Camcorder’s equipped with a composite RCA input. Movie files can then be downloaded to a PC for image processing. image Processing Software Website links are provided above to download popular free Image processing software to be used with your image files to enhance your astro Images. Image Processing Software such as RegiStax or AviStack can Align and Stack (combine) hundreds of individual images into a single resultant image and per form some additional image processing to bring out subtle details or to make the image appear more pleasing overall. Both software applications are a recommended addition to any astro-imagers arsenal of image processing software. Getting Started During Daylight We recommend using the SSVE for the first time during the day. This way, you can become familiar with the camera and its functions without having to stumble around in the dark. Set up your telescope and mount so the optical tube is pointing at an object at least a couple of hundred feet away. Insert an eyepiece and focus as you normally would. To obtain first images with the SSVE, follow these step-by-step instructions: 1. Plug the 9v Power adapter into the SSVE. 2. Plug the RCA composite output from the SSVE into your viewing device (TV, DVR, VCR, Camcorder). 3. To connect the camera to the telescope, simply replace the telescope’s 1.25" eyepiece with the camera. Make sure the securing thumbscrew on the focuser drawtube is tightened after the camera is inserted. 4. You will now need to refocus the camera for the centered object. Focusing will be the hardest thing to learn in the initial stages. If the daytime image brightness is still too bright to produce an acceptable image on your computer screen, you may need to stop-down the aperture of your telescope. 5. Look at the Live Video Window on the screen and adjust the focus knob accordingly to determine best image focus. Note: The camera’s field of view is fairly small. It is approximately equivalent to the field of view through the telescope when looking through a typical (i.e. not wide-field) 5mm Ultrascopic eyepiece. 6. Image orientation can be changed by rotating the camera within the focuser drawtube. Simply loosen the thumbscrew on the drawtube and rotate the camera until the desired image orientation is achieved. Retighten the thumbscrew on the focuser drawtube when done. You may need to slightly refocus (using the telescope’s focus knob)...
