John,

I use a 216XT with a Celestron OAG on my 10" LX200, in stand-alone mode.
It guides OK for the images I have been taking with a 416XTE. The
ability to check focus by downloading an image, especially with the coma
affected images from the OAG, is a plus over the 201. I don't think I
would go the 416XTE/216XT path these days with the great choice of CCD
equipment available now. My 216 is about 6 years old and the technology
has moved on.

Speaking of the 216, How do owners like the 216 in place of the 201?
I'm
thinking of replacing my 201.

Thanks,
John

David,

I took about 10 frames and it did it each time.

I first thought it was stray light external to the ccd, but after
turning
camera in different directions it was a line of hot cells, all at the
bottom
of the frame....

Sooo, I'm thinking it is some internal light...It can certainly be taken
out
when imaging and the number of hits in a 3 sec frame are not real high,
but
if there is some way I can reduce it I'd like to.

Glad to know you saw a similar phenomena, but this is way too consistant
so
I'm suspecting the LCD...

Thanks,

Gary

Does it do it every time? I had that problem with my 216 occassionally
when
I
first started it up, but after it cooled down and settled, it was just
fine.
I haven't used my 216 in a while, though, so I am remembering this only
vaguely, except that it would go away within a few minutes of use.
