To the Right a picture of the Sun imaged
using a special solar telescope which is
tuned to H-alpha wavelength (see
picture above)
Images of the planets in our solar system
were all taken using the Celestron 9.25
connected to a ASI Video Camera and
using a Televue 2.5x Powermate to give
extra magnification. At the very high
magnification used it is very difficult to
centre the planet on the camera chip.
I use a flip mirror in the optical path as an
alignment aid (see picture below)
