Ok guys.. here we go.. I don't know if this subject has been answered again but I'm running a little bit of time I don't have time to go through the posts.

So.. I'm about to buy a small APO for astrophotography. I also own an 8" Newtonian Skywatcher an an EQ6 Skyscan Pro.

I have two choices of APO's.

1. The newest ZenithStar II generation Doublet APO 80mm ED refractor. (1.25" Carbon Fiber plate 99% dielectric diagonal are included in the price)
Price: $600.

and

2. Astronomy Technologies Astro-Tech AT80EDT 80mm f/7 ED triplet apochromatic refractor with carbon fiber tube.
Price: $700

I know that the Astro-Tech is a triplet apochromatic which is better but I'd like to hear your opinions on this matter.

I'll be using it for prime focus astrophotography with a Canon 40D camera on my EQ6 Pro.

I don't know if the quality of optics of Astro-Tech is the same with WO. I've never read any reviews about Astro-Tech. So give me your lights on that.

Thank you for your time.

Clear Skies to all.
