March 30, 2004, 01:16, 01:25 UT. Venus captured under
relatively good seeing near the end of evening twilight. There appear to be some
subtle details captured under visible light (with Edmund IR block filter)
(above) and through a W47 (violet) filter (bottom images).

February 15, 2004, 00:24, 00:31 UT. Venus captured under
relatively good seeing near the end of evening twilight. There appear to be some
subtle details captured under visible light (with Edmund IR block filter), top
three images and through a W47 (violet) filter (bottom image).
October 28, 2003, 19:21 UT (12:21 MST). Venus
captured under poor seeing conditions. Venus was only 10.5
arcseconds in diamter and 94.8 percent illuminated. 203 mm f/7 newtonian @ f/35
(stacked Televue 2x and 1.8x barlows and
extension tube) and Philips ToUcam Pro 740K webcam with Edmund IR blobk filter.
August 30, 2003, 08:32 UT (14:32 MDT). Venus was captured
at only 13 days after superior conjunction (August 18, 2003) and only 3.48
degrees in eastern elongation from the Sun. It is 99.8 percent illuminated,
magnitude -3.9, and 9.7 arcseconds in diameter. More than half of the primary
mirror was illuminated by direct sunlight when this image was obtained.
Nevertheless, Venus was bright and plainly visible through the eyepiece despite
the intense scattered light. 203 mm f/7 newtonian @ f/27 (Televue 2x barlow and
extension tube) and Philips ToUcam Pro 740K webcam with Edmund IR block filter.
!!! BE VERY CAREFUL WHEN VIEWING OBJECTS NEAR THE SUN!!!
December 6, 2002, 11:06 UT. Venus is 41 arcseconds in diameter with a phase of 26
percent and at its greatest illuminated extent. This image was obtained near the
beginning
of morning twilight without an IR blocker. There is no hint of cloud features.
November
17, 2002, 16:28 UT. Venus is 54" in diameter. This image was taken at
almost 9:28 a.m. local time under poor seeing conditions. 8" f/7 newtonian
with ToUcam Pro webcam and Edmund IR cutoff filter @ about f/20.

October
27, 2002, just 4 days before inferior conjunction (the sun was a mere 8 degrees
away in apparent angular separation). These images were each single shots
obtained about noon with an 8" f/7 newtonian and a Nikon CoolPix 4500
digital camera using afocal projection through a 7.0 mm Televue Nagler
eyepiece.
October
19, 2002, 12 days before inferior conjuctions. This image of 12 stacked frames
was obtained near noon with an 8" f/7 newtonian and a Nikon CoolPix 4500
digital camera using afocal projection through a 7.0 mm Televue Nagler eyepiece.
January
8, 2001, 1:16 UT. 8" f/7 newtonian and PC-23C video camera with Wratten
#47 Violet filter and variable polarizer. Venus is 22.5 arc seconds in diamter
and 55% illuminated.
December
22, 2000, 1:30 UT. 8" f/7 newtonian and PC-23C video camera with a
Wratten #47 Violet filter and variable polarizer. Venus is 19 arc seconds in
diameter. Raw image at left and same image with a sharp (level 16) unsharp mask
in Astrostack followed by 3 passes of gaussian blurring (1 pixel) in Adobe
Photoshop.
