Venus, prime focus, WebCam.

Castor (in Gemini), prime focus, WebCam. Double star. The components are of magnitudes 1.9 and 2.9, and the separation is 2.5".

Mars, imaging results. Taken with WebCam without the lens (light directly on chip) with positive projection (9.7mm eyepiece) with field of view about 80x100 arcsec. Processed in Corel Photo-Paint. Images are cropped.
Time: 0700 UT May 14, 1999. The central meridian is approx. 70 degrees, sky north is up, sky east to the left. The north pole is up to the left. The upper dark area is Mare Acidalium and Niliacus Lacus, down to the right is Mare Erythraeum / Aurorae Sinus.

Best images, averages of 4-9 single shots:

This is how the raw exposures look like (cropped):

Mars, 4 imaging results. Taken with WebCam without the lens (light directly on chip) with positive projection (9.7mm eyepiece) with field of view about 80x100 arcsec. Composites of 2-4 frames. Processed in Corel Photo-Paint. Images are cropped.
The small field of view made it very difficult to locate the planet, and to keep it in the field.
The central meridian is approx. 270 degrees, sky north is up, sky east to the left. The north pole is up to the left. The dark area down to the right is Syrtis major and Iapygia, up to the left it must be Utopia and a hint of the northern polar ice cap.
