NiteView main window

NiteView

NiteView is a small Visual Basic application which will shift your Windows 95/98 display to dark reds and grays to minimize the light radiated from the display into your observatory. NiteView also will hide your desktop icons and your taskbar.

Using NiteView

Launch NiteView and then move it to a convienient location on your desktop. It should initially position itself near the upper right corner of your display.

Check "Nite Colors" to shift your display to a set of colors very similar to those set by "The Sky" in night vision mode. Uncheck "Nite Colors" to restore your normal desktop colors.

Uncheck "Desktop" to hide your desktop icons.

Uncheck "Toolbar" to hide your toolbar.

Selecting the Help menu option "Restore Default Colors" allows getting back a standard set of colors in case some mishap leaves you with the night vision colors as your default.

NiteView does not "Remain on Top" ... if you want to access it during the night use altTab.

Polar Alignment

In order to make long exposure astromomical images a camera mount able to compensate for the rotation of the Earth about its axis must be employed. This camera mount, be it simple barn-door or expensive Equatorial motor driven device must have its axis of rotation aligned with the Earths axis of rotation, that is, aligned with the North Celestial Pole (NCP).   

Polaris Trails

Polaris

In the Northern hemisphere, quite by coincidence, we are lucky to have Polaris (the "Pole Star") to guide us to the location of the celestial pole. For many situations, Polaris lies close enough to the true NCP to provide a good feature to align a tracking mount to. However, Polaris lies about a degree from the NCP, and so tracking mounts aligned to Polaris will not be properly aligned with the axis of rotation of the Earth. Aligning to Polaris means that long duration or high magnification exposures will yeild star trails.
