Animation of four of our
digital images captured with the Canon Ixus camera and 20
mm eyepiece attached to the Meade ETX90-EC computer controlled
telescope with full aperture solar filter.
NO GOOD TRANSIT IMAGES - SORRY - WE WERE CLOUDED
OUT
Here is the black drop effect from the
Netherlands just after second contact
Two digital images of the Sun
were taken through a 6 inch f/7.2 Newtonian telescope on a clock
driven equatorial mounting. The Solar filter was a 130 mm off-axis
reduced aperature glass coated filter and the telescope eyepiece was
a Meade Series 4000 Super Plossl 20 mm (1.25" OD). The times are
local summer time. The images shown below are of lower quality than
that taken with the digital Ixus.

Two digital images of the Sun
were taken through a Meade ETX90-EC Cassegrain telescope on a clock
driven alt/az mounting. The Solar filter was a 100 mm glass coated
full aperture filter and the telescope eyepiece was a Meade Series
4000 Super Plossl 20 mm (1.25" OD). The additional instrumentation to
be used for video records of the transit of Venus is also shown
