Initial indications are that the color correction is like a reflector, and the intra and extra-focal patterns are textbook at 300x. The current price for this level of performance is a steal.

When will the 180mm be available?

Now that the seeing has cooperated, I can see that the in-focus airy disk and nearly non-existent first ring are excellent as well. It is almost eerie to rack thru focus and not see any color at all on whitish glints, just like a reflector, but no central obstruction. Moderate glints have that only-an-airy-disk, no-rings look of perfection.
