658RE: [ccd-newastro] Ice Crystals
- Nov 1, 2000Those are almost certainly icing. There is a desiccant inside the camera
that is used to dry the chamber where the chip is located. There is a large
brass plug, removable from outside the camera, that contains the desiccant.
You can remove the brass plug, bake it in an oven for several hours, cool
it, and then replace it in the camera. Your camera should have come with a
black plug, no desiccant, but you can put it in the camera to keep dust out
of the chip chamber.
You can get the specific details of the desiccant recharging process in the
docs that came with your camera, or contact SBIG for any assistance you

Subject: [ccd-newastro] Ice Crysals
I uploaded a file called "holes" for help. I have a new ST8E NABG
that I have had
for about 9 months, but am now just beginning to use it. Prior to
use, it was stored in dry Pelican case.
Now after a few nights of good service, I am now getting these holes
in my images... are these or could they be ice crystals?
1. Can a relatively new camera get these? Granted I have had the
camera for 9 months, but it has be well stored and not exposed to the
2. What do I do now?
