Regardless of what the others have said, you have to realize that the more you load it up the more strain will be placed upon it, resulting in earlier wear and tear, more need for adjustments and maintenance. Think of of it like this-if it's got a load limit, it's for a reason!!

I have since stopped using my 10" and now use an 8"(big size drop between 10" & 8") with an 80mm guider, but more frequently, I am using a 102mm imaging scope with the 80mm guider stacked on top with all cameras and finders etc. Along with a lighter load I also have all round higher accuracy across the whole sky, landing all my targets on the image chips.

Another misconception is that really big scopes are best for imaging. That is true if you want close up shots of galaxies or planets which are generally small and faint, however, larger objects like bigger nebula go over the field of view resulting in cropped images. Smaller scopes will give you a wider field of view and probably as good detail which will result in better images in the long run.
