2.Setup SSHD and viewing device as explained in viewing on TV or Computer section.

3.Remove the eyepiece and insert the SSHD (with 1.25" nosepiece) into the 1.25" eyepiece holder on your telescope.

4.If the image is white on the screen, it’s overexposed. Adjust luminance submenu settings (ALC, Shutter speeds, Gain) as needed to reduce the brightness and blurring.

Barlow to the telescope to increase magnification is not uncommon for planetary imaging (Figure 17). The planets and other solar system objects are relatively bright and can be imaged with a darker or “slower” focal ratio.

High power planetary imaging often leaves the best focus up to your eyes when monitoring the live image. Use the digital zoom tool to aid in focus.

Use the fastest shutter speeds for your telescope and increase gain and other luminance settings as desired. Experiment with your telescope and camera to find the optimum settings for your particular setup.

The best planetary images will be obtained by aligning and stacking (combin- ing) many individual images in order to improve image contrast, brightness, and detail.

A great way to obtain images for stacking is to take several seconds of video of

5.Focus telescope until you get a

sharp image on your computer screen.

6.Experiment with the different camera settings. First use the presets to become familiar with each, then tune and resave each to get the best views for your particular telescope.

Recording Video

The SD video can be recorded onto computer via the included Video Capture Device.

The HD video can be recorded onto computer via the Orion HD Capture Device (Sold Separately)

In order to capture video and use post processing software the video signal must be recorded onto your computer in a standard movie format.

Included with the SSHD is an SD video capture device. This device will record video from the SD output of the camera up to 720x480 (SD resolution) in uncom- pressed AVI format (See Video Capture Device instructions for details).

In order to capture the full resolution HDMI output signal a HD capture device must be used.

We recommend the Orion HD Video Capture Device (Sold Separately).

Planetary Imaging

Planetary imaging is also referred to as Solar System imaging, and includes the Moon, the Sun (with a proper full aperture solar filter!), the planets, and miscella- neous objects in Earth’s orbit such as the International Space Station (ISS). The SSHD is capable of capturing all these objects in real time.

Just about any telescope is suitable for the SSHD when imaging the planets. The longer the focal length of the telescope, the larger and more detailed the images will appear. Unlike deep space astro-imaging, you actually want to have a long focal length and focal ratio for planetary imaging. Adding a 2x, 3x or higher

the planet, then import the video into post processing software. Since the SSHD has a maximum frame rate of 50/60 frames per second, you can literally obtain hundreds of images for stacking in seconds! You save time by taking one video instead of dozens of individual pictures!

It is recommended to capture hundreds (or even thousands) of frames when planetary imaging. The large amount of frames can then be processed using stacking and aligning software such as RegiStax to give the best results.

Since you will be taking multiple images over a period of time, it is important you have a decent polar alignment in order to keep the planet within the field of view of the camera. To this end, having a motor drive (at least single-axis) will also be helpful. Otherwise, you will periodically need to rotate the R.A. slow-motion knob to keep the planet within the camera’s field.

We recommend a telescope mounted on a motorized altitude-azimuth or German Equatorial mount. You can potentially capture the Moon or a planetary image with a telescope that does not track, however you may not get optimum results. The sky moves 15 arcseconds per second! If you are imaging through a long focal length telescope, you essentially need to track the object or unwanted blurring could occur.

Fainter objects will require longer shutter speeds whereas bright objects like Jupiter or the Moon will require very shorter shutter speeds. Adjust as needed for the object you are imaging.

Once you have achieved focus and good luminance and color, you are ready to capture and save images to your computer.

View and Stack

After you have captured your images, you can review them in RegiStax, a free- ware program downloadable from the provided web link in the CD Launcher. Mac users can use the Lynkeos tool to align and stack their images.

We recommend stacking a minimum of 50 images or more. The individual images have low bit depth (255 brightness level counts), and background noise.
