Signal Enhancement Example

Below is given a series of captures taken with a Philips 900 NC web cam positioned in the prime focus of a Newtonian telescope of 900 mm focal length and 130 mm in diameter of the main mirror. The camera has a sensitivity of less than 1 lux and the object captured, a satellite antenna, was situated at 1.5 km distance in plain night, illuminated only by city lights.

The first capture was taken without any alteration of the image, using only the enhancements available in control panel of the camera driver. The following three images were taken with the use of Andromeda enhancements and noise reduction tools.

An image taken during the evening, a few hours earlier, from the same object is also available for comparison.
