15 Focusing Focusing the CCD camera is one of the most critical parts of imaging. It can be challenging, but MaxIm DL Essentials has some helpful featur es which will assist you when focusing your StarShoot Pro. Before focusing, make sur e your mount is polar aligned and tracking. For best r esults, we r ecommend focusing on a star at least 30º ab[...]

16 8. In the Camera Control Window , in the box below the Mode box, select Focus . Click Expose . The camera will only download the area you previ- ously selected, which makes each image download significantly faster than the whole frame. Note: If the StarShoot Pro is grossly out of focus, no object will appear in the image, not even a blur . Incr[...]

17 Caution: Once you have achieved focus, be sure to click the Reset button at the bottom of the camera control window , otherwise the camera will crop all your images into a small square!

T o flat field calibrate: 1. Select Setup Calibrate in t he[...]

24 Combining Deep Sky Images Each individual deep sky image is faint and has a noticeable amount of noise. Combining the individual deep sky images eliminates the noise and enhances the detail in the deep sky object by impr oving the signal to noise ratio. The more images you combine, the better the resulting image will look. (Figur e 17a and Figur[...]

25 Note: In addition to Average mentioned above, 3 other different combining methods can be chosen: Sum, Median, and Sigma-Clip. T o learn more about these combine methods, see “Image Processing – Combine Methods”. The pr ogram automatically moves to the next image. 6 Center the crosshairs on the same star in this new image, and left-click ag[...]

32 superior due to the elimination of extra r eadout noise and the residual blurring caused in realigning the images. When taking long exposures with astr onomical telescopes, motorized tracking is requir ed to compensate for the Earth’ s r otation. Most telescope mounts do not track accurately enough for long-exposure imaging without some form o[...]

33 can be very tiresome and tedious, however , especially if taking many long exposures throughout the night. The StarShoot Pro can be used as an “autoguider” to take the place of the observer so that no manual guiding corrections are needed during long expo- sure imaging. Keep in mind, however , that when the StarShoot Pro is used in this way [...]

After you have selected your tele - scope model, click the Properties button. 9. In the window that pops-up, choose your specific Scope T ype and desired S[...]

35 Autoguider Calibration In order to properly control the mount, you must calibrate the system. The exact orientation of the StarShoot Pro, the focal length of the guide telescope optics, and the speed of the motor drive all affect the calibration. T o perform autoguider calibration: 1. Switch to the Guide tab. 2. Set the X and Y Aggr (aggr essive[...]

36 telescope does not move, check the Settings . Remember , you have to set up a method for sending the autoguider commands to the telescope! 11. The star should move in an L shape. If it does not move enough, a warning message will appear . The r ecorded positions will be displayed in the scr oll- ing log, along with any err or messages. Note: If [...]

37 • On most telescopes, the Right Ascension drive likes to have some load pushing against sidereal tracking. If the mount is balanced such that it is pulling the mount forwards slightly , the gear teeth may bounce back and forth resulting in terrible guiding that cannot be corr ected by an autoguider . Be sure to always balance the telescope suc[...]
