Hi guys.
I'm heading down the SCT track soon (real soon

) And was wondering this:
My ideal SCT would have to be the C9.25 OTA only, based on (LOTS) of reviews & photographs posted by guys such as Robert_T/Rumples/Dennis & Matt, to name but a few.
$2300 + shipping AU & it would fit snugly on my motorised EQ5 like a bug in a rug
I also have the opportunity to purchase a second-hand 10 yr. old C8 OTA only...for a THIRD of the price of the C9.25 (the black one with the orange 'CELESTRON' on it) Which supposedly has 'fine scratches' on the corrector plate..Would this be a concern, these fine scratches??
Whatever I purchase, I will only be doing imaging with it, very little visual stuff.
Also, please bear in mind I know NOTHING about SCT's. Never even seen one before except in photo's.
Can anyone tell me about this Black tubed C8 ?
Any help appreciated & comments welcome.
