      Sky-Watcher Evostar 150 ED Refractor

      For anyone interested, I joyfully received my Sky-Watcher Evostar 150 ED 4 days ago. The seeing conditions since then have not been kind (darn telescope gods) but last night, after the clouds cleared, the seeing unexpectedly settled down to about 7/10. Scope verdict: Absolutely stunning glass! Once cooled, this lens is incredible. After initial setup, and peering through the sucker holes in the clouds, the scope star tested out to about 1/5th wave @240X (according to Suiters book images, Ronchi, and Aberrator 3). Just an average scope. Testing again, after about an hour or so after the parting of the clouds (about 90min after sunset), revealed a smooth, highly corrected optic that almost knocked me off of my observing chair. WOW is truly the word for expressing this telescope's performance! No zones, astigmatism, edge defects, or roughness. I’ve been doing the "scope thing" for a long time (over 40 years). This has to be one of the best, if not the best, star test I have ever seen in a refractor this size or greater. After some minor focuser rework (smooth as glass and now holds my 2" prism diagonal without slippage), this scope is about as close to perfection as this lowly scope user dares to get. In focus stars (after cooling) revealed no false color to these 67 year old eyes, all the way up to 375X. Venus was surprisingly good. The very minor false color I did see came from atmospheric tremors. I had the same result with the moon. For the type of observing I do (moon, planets, multiple stars), this scope is “off-the-chain.” I’m looking forward, with great anticipation, to a night of good seeing and the coming evening planet parade. Superb job Sky-Watcher!
