I have been following APM's quite lengthy development of this scope via the detailed notes they have had for some time on their website. It has been a while coming but it is now a reality.
I have been interested from a visual observing perspective. In my view a well corrected doublet is strikes the right balance between all the competing design variables and of course price, for visual observing. The detailed specs suggest a highly corrected image for a doublet. Combine this with the other advantages of a doublet, particularly less weight, suggests a value for money visual instrument.
Perhaps the nearest doublet competition would be the venerable Tak FS 152 which sets the benchmark for large doublets. These seem to fetch $7-8K secondhand. So, if this new APM offering comes close to the Tak's performance I would be very happy at almost half the price.
I will read future reviews and comparisons with interest. Shall try very hard to keep the wallet under lock and key in the meantime.
Steve.
