next upgrade?

hi,

for the past three years i've been using an 8" Celestron Dob and
enjoying it. lately, i've been using my canon a40 to shoot pictures
through this. i'm just wondering...should i change scopes and since
i've been kinda spoiled with this 8", what would a good change be?

i have a highend 35mm camera that could mount on an auto scope...but
i'd kinda feel like i'm cheating...sorry...can't help that.

thanks!
