A fellow observer recently sent a website for AstoTech carbon-tube refractors using Astreya objectives. The objective is described as a four-element SuperAPO. The carbon tube assemblies are beautiful and overall the scopes with the Astreya lens looks very interesting. Anybody out there actually using them?

Been watch this from the sidelines. Some mention on
yahoo refractors and SUPERAPO_refractors. Also some
mention on astromart russian_optics. But no first-hand
user feedback that I can see. Some grumblings about
centering of the middle doublet, but can't judge
veracity or significance.
