Differences in Refractor and Reflector for Astrophotography

Well, i have had my celestron 130EQ Telescope for about 2 years now and i wanted to get into deep space imaging. Looked up some Deep Space imaging setups and what they got out of their equipment and this caught my eye.

And I saw that his imaging scope was the Saxon ED80 and the specs were focal ratio of f/7.5 and a 600mm focal length.

Then i found out that the celestron was
Aperture 130mm (5")
Focal Length 650mm
Focal Ratio f/5

So i take it that i would get around the same amount of viewing(imaging) capability with my scope. Generally speaking.

I know i could be very wrong, but i was just asking.

Forgot to add that i NEED to add a Barlow if i was to use it for astrophotography or else it wont focus..
