Take Picture Menu You can take wide-field images of the night sky with the ECLIPS CCD Module that is part of the LightSwitch alignment system. It’s great for constellation shots and you can see some large bright deep sky objects as well. Note that while you take and store images on to a user supplied Mini SD Card for download to your PC, to fully use many of the options below and to preview your The Pleiades Star Cluster (M45 ) image you need to connect the LS to a user supplied external video monitor. Start by selecting “Take Picture” from the top menu: “Take Picture” > “ENTER” Then you will see the following options: • Preview Exposure: Displays “Finder Image; Exposing...”. UP/DOWN adjusts Exposure Time (ET). A longer exposure records fainter stars. A shorter exposure records fainter stars. A shorter exposure is better for very bright subjects. AUTOSTAR III major change in apparent magnitude as one of the two • Set Contrast: UP/DOWN selects scrolls throughstars passes behind the other. The combined magnitude the thirteen pre-set Contrast curves available, of the two stars thus dips from +2.1 to a minimum of “Cont. Day”, “Cont. Moon”, “Cont. Planet”, “Cont. 25 INDEX Stars”, and “Cont. Deep1” thru “Cont. Deep9”. The setting after “Cont. Deep9” is Cust.Cont. (Custom Contrast). This setting allows you adjust the Contrast AND Brightness to create your own setting. Contrast is controlled using the LEFT/ RIGHT Arrow Keys. Brightness is controlled using the UP/DOWN Arrow Keys. NOTE: to fully utilize these the Custom Contrast setting you will need the use of an external monitor. Otherwise chose one of the thirteen pre-set Contrast curves. • Shoot & Store: Allows you to take the image and save it to the SD once you have adjusted the settings and are happy with the preview. You must have an Mini SD Card formatted with the FAT32 file system inserted in the telescope to use this function. Press the “BACK” key to save the image. • Dark Calibration: Allows you to take a dark frame of the same exposure as your image but with the camera lens covered to combine and subtract out noise from your image. You must cover the camera lens with the lens cap before you take the dark calibration frame. Deep Sky Imager (DSI) Series: these high- performance, easy-to-use and affordable color and black and white CCD camera suppresses electronic noise and by not compressing data from the sensor to increase picture quality. The Deep Sky Imager uses a full 16-bit analog-to-digital converter to enhance picture depth, contrast and dynamic range. The DSI series are USB compatible to easily interface with most Windows-based laptop computers. It includes AutoStar Suite which automatically sorts, aligns and combines the best images, resulting in a AUTOSTAR III highly detailed color image. The following Deep Sky Imagers models and accessories are available: Deep Sky Imager III (DSI III) Deep Sky Imager Pro III (DSI PRO III) Deep Sky Imager II (DSI II) Deep Sky Imager Pro II (DSI PRO II) Deep Sky Imager Pro II (DSI PRO II), w/RGB Color Filter Set Utilities Menu The Utilities menu provides access to several extra features within LS: Volume: Adjusts audio volume of the telescope using the Scroll keys. When complete, press “ENTER”. HBX Brightness: Adjusts the brightness of the display using the Scroll keys. When complete, press “ENTER”. HBX Contrast: Adjusts the contrast of the display using the Scroll keys. When complete, press “ENTER”. Night Vision: When you have an external video monitor attached to your telescope, you will fi nd the bright colorful displays may affect your night vision and make it difficult to see dim objects in the eyepiece of your telescope. The human eye’s sensitivity actually increases for about the first half hour you are in the dark. You have noticed this when you walk out of a dark theater into the daytime sun, how over bright the day seems. This dark adaptation of your eye can be reduced by white light. Red light does not have this effect on dark adapted vision. The night vision option on your telescope will change the display from color, to shades of red. There are three settings: Auto – The video will automatically switch to red at night. On – Selects full-time red video. Off – Selects full-time color video. INDEX Sleep Scope is a power and time saving option that shuts down the LS telescope without forgetting its alignment. With “Sleep Scope” selected, press “ENTER” to activate the Sleep function. LS goes dark, but the internal clock keeps running. Press any key, except “ENTER”, to re-activate LS. Park Scope is designed for a telescope that has not moved between observing sessions. Align the telescope one time, then use this function to park the telescope. Next time it is powered up, no alignment is required. Pressing “ENTER” causes the telescope to move to its pre-determined Park position. Once parked, the screen prompts to turn off power. IMPORTANT NOTE: When the “Park Scope” option is chosen and the display prompts y...
