Welcome to a new world of adventure. Your new StarShoot Deep Space Monochrome Imaging camera II (SSDSMI-2) is capable of capturing detailed images of astronomical objects; galaxies, star clusters, and nebula, as well as the planets, Moon, and the Sun (with optional solar filter). These objects can be imaged to create spectacular views on your computer (laptop recommended, see “System Requirements”) which can be saved for emailing or printing later. You’ll find that this relatively inexpen

T-threads Figure 2b. If your telescope has T-threads, remove the nosepiece from the SSDSMI- 2 and thread the camera directly onto the telescope. This provides the most secure connection. In order to reach focus, the telescope must have approximately 0.6" (15mm) of inward focus travel relative to where a standard eyepiece focuses. If your telescope does not have enough inward focus travel, you will need to use and optional 1.25" barlow lens to extend the telescope’s focal plane to the camera

Computer A computer is needed. For astro-imaging in the field at night, a laptop com- puter is highly recommended. Maxim DL Essentials requires Windows 2000, Windows XP, or Windows Vista. The following hardware is also required: • Processor – Pentium™ or equivalent, or higher • Recommended minimum memory size is 64 MB. • Disk Space – 67 MB for program installation, 100 MB swap file recom- mended • Video Display – 800 X 600, 16-bit color or higher. 1024x768 or higher is recommende

Tab - + USB cable D-cell batteries (2) Input jack for 3VDC Power supply TEC power Figure 3. The 3V power supply (with two D-cell batteries installed) turns the TEC on when it is plugged into the SSDSMI-2. When the 3VDC power supply is plugged into the SSDSMI-2, the TEC is on (Figure 3). It takes about a minute for the TEC to provide maximum cooling, so wait a couple of minutes before you begin to capture images. When the power source is not plugged in, the TEC is off. Remember

Getting Started During Daylight We recommend using the SSDSMI-2 for the first time during the day. This way, you can become familiar with the camera and its functions without hav- ing to stumble around in the dark. Setup your telescope and mount so the optical tube is pointing at an object that is at least a couple of hundred feet away. Insert an eyepiece and focus as you normally would. Since the SSDSMI-2 camera is so sensitive to light, you will need to “stop down” your telescope aperture t

Obtaining First Images To obtain first images (in daylight) with the SSDSMI-2, follow these step-by- step instructions: 1. With an eyepiece inserted in the telescope, center and focus an object that is approximately 1⁄4 mile away. If you cannot focus your telescope this closely (due to lack of back-focus travel), then you will need to utilize an optional extension tube (available from Orion). 2. Plug the camera into your computer’s USB port. 3. Open Maxim DL Essentials by clicking on the icon

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) 10mm focal length eyepiece. So make sure the object to be imaged is well centered in the telescope before connecting the SSDSMI-2, otherwise it may not appear in the field of view of the camera. 10. Once focused, image orientation can be changed by rotating the camera within the focuser drawtube. Simply loosen the thumbs

Figure 9. The settings in the Screen Stretch Window greatly determine how an image will appear on your computer screen. Figure 10. A histogram is a visual representation of the range and levels of brightness in an image. Range of brightness levels When an image is displayed, you will notice a graph in the Screen Stretch Window. This is called the “histogram” of the currently displayed image (Figure 10). A histogram is a simple bar graph that shows the range of brightness in an image. Each

Simply left-click and then drag each arrow to adjust it to the desired level. The best results are obtained by adjusting the arrows (numbers) until the most pleasing display appears. There are also seven automatic settings in the Screen Stretch Window. Typically, Medium will give good results for deep sky objects, so the default screen stretch setting is Medium. Inste

Since you will be taking multiple images over a period of time, it is important the mount be polar aligned in order to keep the planet within the field of view of the camera and to prevent image blurring due to poor tracking during each exposure.

5. Now, in the box beneath the Mode box, choose Autosave. Set the number of images you would like the camera to take under Autosave (start with 10 or so), select the file folder in which you would like to save the images with Folder, and enter in a Base filename for the captured images. Typically the name of the object being imaged, such as “Mars1”, will be entered here. If “Mars1” is the Base filename, and you choose to Autosave five images, then the images will appear in the selected file fol

Figure 13. The Combine Images window allows “stacking” of individual images into one high-quality resultant image. Imaging Deep Sky Objects To capture breathtaking images of deep sky objects, such as galaxies, nebu- lae, and star clusters, much longer exposures are needed. As with planetary imaging, you will take several individual images and stack them together to form one high-quality resultant image. But while planetary images are formed by stacking many exposures of less than 5 seconds,

3. Precisely focus the camera by using the telescope’s focus knob and the Focus setting in the Camera Control Window. Set the Mode to Light 1x1, and try an exposure time of a few seconds to start. Use the Medium setting in the Screen Stretch Window. The focus point for the SSDSMI-2 will be approximately 15mm inwards from the eyepiece’s focus point. If you are having trouble determining best focus, try focusing on a bright star near the deep sky object. If there are no suitably bright stars

Note: In addition to Average mentioned above, 3 other different combining methods can be chosen: Sum, Median, and Sigma-Clip. To learn more about these combine methods, see “Image Processing – Combine Tips”. 10. Now, find a well-shaped (circular) star in the first image displayed. Use the mouse to center the crosshairs on the selected star and left-click. 11. The next image will now be displayed; center the crosshairs on the same star in this new image, and left-click again.

To take dark frames for subtraction from “light” images: 1. In the Camera Control Window, set the Mode to Dark 1x1. 2. Set the exposure time to whatever you set it to (or will set it to) for taking actual (“light”) images. Note: When taking dark frames, do not change any of the settings in the Setup button from what they were (or will be) when “light” images are taken. 3. In the box beneath the Mode box, choose Autosave. Now set the number of dark frames you would like the camera to take unde
