I agree that there are probably no GSO RC 16"s delivered as yet, based on info on the Andrews Communications website. I sighted that development as an example of their (GSOs) movement into the larger scope mass market, which is supported by their advice to me that they will be introducing a 20" Dob later this year, and their apparent competitors 18"dob comiing as well.
From what I have read I expect that most GSO optics are produced on machines, and that does provide for a certain quality level in mass produced products. They don't produce individual mirror test results but 'claim' a certain level of qualty for their products based on the processing system design and sample testing. I would never expect a mass market producer to be able to duplicate the manhours put into a hand made mirror by an experienced optical specialist dedciated to just the high end of the market. But GSO are bringing astronomy to the masses and at a quality level which is very good compared to past industry offerings and they should be commended for that. Quality wil certainly continue to improve as optical robotics are further developed. As a base for further development and upgrades a GSO scope ticks alot of boxes for many people.
Mark, et al, maybe there needs to be a separate topic thread on mirror quality issues and the cost benefit (or not) of custom hand made verse robotic.
