On the Wavelet page, use the wavelet sliders (H) to enhance the image.

The power of RegiStax is in the usage of wavelets. This is a special

filtering technique that is very good for enhancing details in images.

Each wavelet layer carries part of the image within it. The lower numbered

wavelets control the fine detail stored in the image, while the larger

numbered wavelets control the coarse detail. Each layer can be adjusted

individually to reveal the desired amount of detail for your image.

Finally, press the Save Image button to save the final image.

COLOR AND MONOCHROME

ACCESSORIES

An optional IR-Block filter is available for Skyris color cameras. Digital cameras

are very sensitive across visual and infrared spectrums. While imaging in infrared

(IR) can be desired in some cases, consider blocking the IR to keep the best

sharpness and color balance in your astroimages.

Skyris monochrome cameras require the use of Red, Green, and Blue (RGB)

imaging filters to achieve a color image. A filter wheel helps you easily toggle

between the filters while imaging. A Skyris Filter Wheel is available from

Celestron (filters not included).

TIPS

FOCUSING

To achieve best focus, concentrate on a high contrast feature of the object you are

imaging. Focusing on small features such as a moon's shadow on Jupiter or Cassini's

division in the ring of Saturn will guarantee best focus across the entire image.

Once the frames of your video are stacked, the overall brightness of the composite

(stacked) image is usually brighter than its individual component frames. For this

reason, it is best to keep the brightness of the video image seen on the screen

dimmer than you would normally desire. It is important that no part of the image is

over-exposed to assure the maximum amount of detail in the final composite image.

COLLIMATION

No matter what type of telescope you image with, poor collimation (alignment of

the optics) will ruin your chances for a good image. Before you begin imaging,

always check the collimation of your instrument and make adjustments if necessary.

Refer to your telescope's owner's manual for instructions on collimating the optics.

FINDING OBJECTS

At first it can be difficult to locate individual planets due to their relative brightness.

To make it easier to initially find your object in the imaging window, increase the

brightness and gain controls on the Device Menu Properties. This will allow you to

better see the object as it passes through the imaging window. Once the object is

located and centered, you can adjust the setting until the object is at the desired

brightness and contrast.

HOW LONG TO TAKE STREAMING VIDEO

You may think that the more frames you record the better. However, there are
