SCT's black spot ?

Hi all,

Well finally got my 6" Meade ACF SCT (after original mount deemed irreparable) on a manual AZ-EL mount using rings and a dovetail, added quite a bit of weight too.

Now I know about the central mirror but notice a pronounced spot in the middle when using low power eyepieces in particular. I am guessing at night not so noticeable but I have it set up watching some birds just for testing and getting used to focussing etc.. No scale reference like my refractor has.

So all you SCT users is this totally normal like the Dob hole I see so much written about ?

Any feedback welcome.
Cliff
