Hello,
I came across a new(ish) mirror on offer for newtonian telescopes that DO NOT require a (traditional) mirror cell and only have 1 single collimation point.
Seems like a lot of weight can be saved and single person collimation made a lot easier on large dobs.
Has anybody tried these mirrors, or seen an independent report on them?
Thanks
Steve
