All these pictures were taken at prime focus with a 10 inch Meade LX200 GPS telescope and a cooled Logitech Quickcam Pro 4000.

This is what I call a 'quick and dirty' webcam experiments webpage.

Experiments to determine useful range of webcam settings.

Gain
Gain controls how much the electronic signal is amplified - Jupiter images are brighter with more gain, but also more noisy.

Brightness.
Self explanatory?

Gamma
Adjusts mid-tones without affecting the brighter or lighter areas.

Saturation
More saturation means pure or strong color, less saturation means paler or weaker color. Lower saturation gives a duller/grey image.

			2 not enough gamma, 1 looks better
1) 60 Brightness; 50 Gamma; 100 Saturation; 20 Gain	2) 60 Brightness; 0 Gamma; 100 Saturation; 20 Gain	3) 60 Brightness; 0 Gamma; 75 Saturation; 20 Gain
			4 and 5 - 30 gain too much (overexposed), previous row of 20 gain better. 6 best of these 2 rows so far
4) 60 Brightness; 0 Gamma; 50 Saturation; 30 Gain	5) 60 Brightness; 0 Gamma; 75 Saturation; 30 Gain	6) 60 Brightness; 25 Gamma; 50 Saturation; 25 Gain
			Whole row 50 brightness seems better than both previous rows at 60 brightness. 9 with 75 saturation looks best. 7 and 8 with 100 saturation seems oversaturated.
7) 50 Brightness; 0 Gamma; 100 Saturation; 30 Gain	8) 50 Brightness; 0 Gamma; 100 Saturation; 30 Gain	9) 50 Brightness; 0 Gamma; 75 Saturation; 30 Gain
			12 overexposed. 10 looks great.
10) 50 Brightness; 0 Gamma; 50 Saturation; 30 Gain	11) 50 Brightness; 25 Gamma; 50 Saturation; 30 Gain	12) 55 Brightness; 10 Gamma; 75 Saturation; 30 Gain

Conclusions?

• 0 gamma not enough. 50 too much

• 20 gain OK, 30 too much

• 50 brightness better than 60

• 75 saturation looks right, 100 is oversaturated
