Interesting, as per my original post, 50sq inches compared to 28sq inches = 1.78 increase.
Astroboyz, I had my 8" Newt on an EQ5. A HEQ5 should cope more than adequately.
But as I did not do much serious astrophotography, I soon found comfort of observing was more important and now I have a 12" Dobsonian.
I used to (like every newbie seems to) think Astrophotography was a natural progression, and hence I ventured down the EQ path. But now I strongly suggest to new comers, unless you definitely intend to spend the time and money required to practice astrophotography, settle for observing (at least initially), and go DOB. That would have saved me heaps of money and frustration. But like most I didn't listen.
