These photos were taken with a Philips ESP-80 Digicam mounted
on a conventional photographic tripod and arranged to look into the
eyepiece lens of an 8" f/8.25 Newtonian telescope on a Dobsonian mount.
This is a very tricky arrangement to set up because of the close
positioning of the camera lens to the eyepiece and the necessity
to frequently reposition the telescope (not driven) to keep the
image in the field of view. Plans are afoot to mount the camera
directly onto the telescope tube which will greatly alleviate this
tiresome problem.
Note: Being astronomical photos they are 'upside down' with respect to conventionial photographs. |
