Way back in DEC 2016, I reviewed the new ultra-economical Explore Scientific FirstLight AR-102 F10 kit / https://www.cloudyni...hinese-imports/. That was my first hands-on experience with China-made refractors -- my APM 152ED is my latest.
Thanks to the folks at Teleskop-Express, I'll review the Bresser Messier AR-102L/1350 OTA in this thread, from shipping time, to packaging, to fit / finish / functionality, to everything I can think of -- and that y'all have questions about.
The Big First Question: Will this scope renew interest in (& buying!) high F-ratio achromatic refractors? We will see...
I have some new tools for this review that I didn't have before: a DPAC rig to objectively assess the optical quality; and, a deep-sky digital imager to (hopefully!) make pictures of the star test results.
I placed the order today. It was marked IN STOCK. How long will it take to get from Germany to The Swamp?
