Has anyone done a visual observing comparison between a C8 SCT with Starbright coatings and a C9.25 SCT with XLT coatings? Visual only, please.
I have read all I can find on CN and see many opinions and theories and quoted numbers, but haven't found anyone who said that they actually looked through both enough to know if the C9.25 XLT enables someone to see any more detail or any more faint objects visually when compared to an older C8 with only Starbright coatings.
I read that moving from Starbright coatings to XLT coatings in the same OTA size is barely noticeable. I also read that moving from an 8 inch SCT to a 9.25 inch SCT is barely noticeable. (that you really need to step to an 11 inch to get any significant impact)
I have a 1998 C8 Starbright SCT and might have the opportunity to replace that with a new C9.25 XLT SCT. Although the OTA price is good, I would need the larger dew shield, heater strip and case, so there is still a lot of money involved.
I am a visual observer only. What difference, if any, good or bad, will I see in my eyepiece if I make the change?
I use an EQ6-R mount so have no issue with the weight. I know I will lose some field of view. With my C8, I use 1-1/4 and 2 inch eye pieces with and without a focal reducer, and use both a 2" Baader BBHS Mirror diagonal and a BBHS T2 prism diagonal.
