ASTROVID StellaCam3 - CONTROL BOX

The following describes the function on the StellaCam III Control Box:

  • FRAME DIAL - HIGH SPEED SHUTTER MODE (LABELED HIGH)?This is the planetary, lunar and solar imaging mode. The Shutter speeds are labeled HIGH 1,2,3,4,5,6. They correspond to shutter speeds of 1/60, 1/125,1/250,1/500, 1/1000, 1/2000 second. This should cover almost all planetary fast imaging modes.

  • FRAME ACCUMULATION MODE (LABELED SLOW) - This dial is the setting used to accumulate frames within the camera. The box is labeled OFF (1/60 second mode), 1,2,4,8,16,32,64,128,256. These are the number of frames accumulated. It related to exposure times for the cameras. There is a chart on the reverse of the control box giving the exposure times for EIA (US Standard) and CCIR (PAL or overseas standard).

  • UNLIMITED INTEGRATION TIME MODE (LABELED START/STOP) - Use this mode only for deep sky objects.This is the mode for very deep imaging of deep sky targets. This mode is quite easy to use. Turn the top dial to the position with the arrow for the Start/Stop position.To start the image press the red start button. It will lock in a depressed mode. During the time it is locked in place the camera will be exposing. To end the exposure press the red button again. The image will now appear on the screen. The image will stay in place as you start another exposure and for the duration of that exposure. Your new image will appear when the stop is pressed again.

  • GAIN DIAL - CAMERA GAIN CONTROL - The gain control acts to boost the strength of video signal. It can be used to bring out faint detail by increasing the gain by going from LO (0dB) to HI Gain (38dB). As it can introduce noise you want to keep the gain as low as possible. For most deep sky objects you will not need to increase the gain beyond the mid-level setting.

  • IRIS - IRIS SLIDER - This allows the user to mount an auto-iris lens. This is a type of lens that opens and closes in response to light level changes. It will keep the lens iris open in dark conditions and close the lens iris down in light conditions. There are two types of auto iris lenses VIDEO and DC. The StellaCam III can use both types as the camera will switch to the proper type automatically.

  • FREEZE INDICATOR - The red led will light when the picture on the screen is frozen. It can be used in any frame dial mode.

  • READ-OUT INDICATOR?The green led will light is synchronous with the readout timing of the CCD.
HOW TO USE THE STELLACAM3 ( StellaCam II Mode)

Deep Sky ?Frame Accumulation Mode (StellaCam II Mode)

  • Connect all connections to the camera, plug in the power supply as described in the instructions. Attach the camera to a monitor or television.
  • Attach the camera to the telescope via either the focal reducer or 1.25 inch adapter.
  • Start by making the following adjustments on the control box. A. Frame accumulation set to OFF, 1 or 2. B. Turn the gain up to mid range C. Set Gamma to LO
  • Go to a star field and and focus on a fairly bright magnitude 1 to 4 star. If you use the frame rate of 0,1, or 2 you will be able to focus in real time or almost real time.
  • Once in focus you can increase the frame rate to 256. The gain to the mid setting and gamma to LO. You should see stars in the background now.
  • Next, go to a deep sky object. A brighter deep sky object is good to start with. Ie. Orion Nebula, Andromeda Galaxy, Dumbbell Nebula, or Ring Nebula.
    1. Once at the deep sky object make the following adjustments to the control box. A. FRAME DIAL 256 Frame accumulation B. GAINýMid Level Setting (12 O'clock Position ) C. Gamma LO
    2. Once you get an image on screen that you really like you may freeze the frame. This will keep the image on the screen. To Freeze the frame press the Red button on the side of the control box in. To go back to the real time video image press the Red FREEZE Frame button again.
    3. Gain adjustments can be made to bring out fainter detail by increasing the gain. Contrast enhancements can also be made to enhance faint details
HOW TO USE THE STELLACAM3 ( Unlimited Deep Sky Integration)

StellaCam3 UNLIMITED INTEGRATION MODE (LABELED START/STOP) - Use this mode only for deep sky objects.

  • Connect all connections to the camera, plug in the power supply as described on page three. Attach the camera to a monitor or television.
  • Attach the camera to the telescope via either the focal reducer or 1.25 inch adapter.
  • Start by making the following adjustments on the control box. A. Frame accumulation set to OFF, 1 or 2. B. Turn the gain up to mid range C. Set Gamma to LO
  • Go to a star field and and focus on a fairly bright magnitude 1 to 4 star. If you use the frame rate of 0,1, or 2 you will be able to focus in real time or almost real time.
  • Once in focus you can increase the frame rate to 256. The gain to the mid setting and gamma to LO. You should see stars in the background now.
  • Next, go to a deep sky object . A brighter deep sky object is good to start with. Ie. Orion Nebula, Andromeda Galaxy, Dumbbell Nebula, or Ring Nebula.
    1. Once at the deep sky object make the following adjustments to the control box. A. FRAME DIAL 256 Frame accumulation B. GAINýMid Level Setting (12 O'clock Position ) C. Gamma LO
    2. Once you get an image on screen that you really like you may freeze the frame. Do a test exposure to make sure you have the deep sky object in your field of view. If you are going for really faint objects they may not appear in this mode
    3. Turn the top dial to the position with the arrow for the Start/Stop position.
    4. To start the image press the red start button. It will lock in a depressed mode. During the time it is locked in place the camera will be exposing. We found that exposures of one minute are excellent at picking up a large amount of deep sky information.
    5. To end the exposure press the red button again. The image will now appear on the screen.
    6. The image will stay in place as you start another exposure and for the duration of that exposure. Your new image will appear when the stop is pressed again
HOW TO USE THE STELLACAM3 ( Planetary Imaging Mode)
  • Connect all connections to the camera, plug in the power supply as described in the instruction manual.
  • Attach the camera to a monitor or television.
    1. Attach the camera to the telescope via 1.25 inch adapter.
    2. A Barlow lens is recommended to increase magnification. We recommend TeleVue Barlow's.
    3. For full lunar or solar disk imaging we recommend the ATIK 0.5X focal reducer. This fits right on the end of the 1.25 inch adapter for the camera.
    4. To begin your planetary imaging look at the control box. The top dial is the Frame Dial. You will use the positions 1-6 on the top dial labeled HIGH. This is the high speed shutter mode. This is the planetary, lunar and solar imaging mode. The Shutter speeds are labeled HIGH 1,2,3,4,5,6. They correspond to shutter speeds of 1/60, 1/125, 1/500, 1/1000, 1/2000 second. This should cover almost all planetary fast imaging modes.
    5. You want to set the shutter speed to the fastest shutter speed that will still give you a bright onscreen image.
    6. You will also use the dial label Gain. Start with the gain in mid-position. The is a position mark LO and a Position marked Hi. LO corresponds to the lowest gain setting and HI corresponds to the highest gain setting. The goal is to keep the gain as low as possible with the fastest shutter speed possible. This will keep your planetary images noise free.
