Dark Image on Sun

Harold,

did you have the camera zoomed in at all? Also, what kind of adapter do
you have for the camera/ep combo? Scopetronix sells a few and I've had
good luck with the Digi-T system they sell with my Casio QV-3500 EX
camera.

Craig,

Thank you for your reply. That shot was taken with a 32mm. I tried a 25mm but
that too gives me a dark area. I have a 15mm, but that magnifies the sun too
much to get a full disk.

Does it make any difference if I use a diagonal? The diagonal makes it easier to
see the viewer on the back of the camera.

One question I have is what EP were you using? It looks to me like you
have the shadow of the secondary there. This would be caused by using an
EP with too large a focal length. My guess is you used a 40mm ep for
this shot.

I just bought an adaptor for my Kodak DX3500 digital camera to fit my Celestron
8i. When viewing the sun on the camera's digital viewer, I get a dark spot on
the sun as shown in the picture here. I do am using a sun filter.

What is causing that and how can I eliminate it?
