thoughts on 2nd hand 16"
Dear all,
I have the opportunity to obtain a 2nd hand Meade 16" Newtonian for about the price of a new 16" GSO primary. I have been very happy with my 12" gso but contemplate an upgrade to 16-18" in the next few years, but finding a quality 16" primary at a good price could accelerate my plans. The vendor says that the mirror was crafted in the US in 1992 and is optically superior to the current Chinese primaries (quoting 1/4 wave error for the current Meades vs 1/8 for the older model). Do people think that this would be true and would the difference be significant? Is the difference between a 12" and 16" under dark skies significant? I had been planning to take some time looking through various scopes at star parties before upgrading, but this opportunity has pre-empted this groundwork.
Any thoughts would be greatly appreciated.
