would you say a new c6 with starbright xlt coatings is the equivlent of an older c8 with starbright coatings or would the older c8 still come out on top.

The 8 inch has almost 80% more mirror area and potentially 33% greater resolving power. Coatings can not make up 80% nor do they increase the resolution...

C8, hands down... no contest.

The C8 is 2" bigger, so it's gonna come out on top no matter how you cut it! I have a C6 with the XTL coatings, and will have a older 90's C8 dropped off by Fed Ex Wends, so i can do a side by side.

Sorry...the C8 will still blow its doors off. An XLT C8 presents a _slightly_ (but noticeably) brighter image than a Starbright C8, but the difference is subtle.

I actually had a C6 XLT with an early 90's starbright C8. The difference was noticeable immediately on any object, the C8 was much better.
