I would just like to thank Darren for making the effort to write a review on the 10" GSO Dob. I know from personal experience writing these reviews takes quite a bit effort and time.
I found Darren's review interesting, informative and if I was in the market for such a scope, would be most useful to me.
WRT the secondary size issue, I note Darren in his review specificaly gives an approximate obstruction figue only - (quote) "central obstruction : 23% (approximately)" (end quote). It might be worthwhile checking to see if the latest 10" GSO dobs are being fitted with a different sized secondary.
Regards to all
