Back earlier this year when all the sunspots were wandering around the
surface of the sun, I thought I would try and take some CCD snaps of
them using a little 60mm Celestron refractor and their solar filter
made just for that scope. I had a small 360x240 camera connected to
the Orion Steady Pix mount and fortunately the camera was not
centered.
I was trying to get the scopes shadow down to a circle when the filter
fell out. Almost immediately smoke started rising from the
camera’s body. I swing the scope around, away from the sun.
After taking the camera off the mount I found a tiny hole burnt almost
all the way through the body. Surprisingly the camera still works, but
the experience scared the WFS out of me.
I have now made sure that the filter is FIRMLY attached to the lens
cap, but I do not think I will ever look through the eyepiece of a
telescope pointed at the sun again. Well, all right I am already
drooling over the Coronado P.S.T.
Clear eyes,
James King
