I've been so happy with the refractor-like performance of my 40-year old Mizar Comet (100mm F8 Newt) that when this 130SL popped-up on ZEN, I just had to buy it... Why? Because of that little Lambda sticker by the focuser -- and its 1/20th Wave optics:
Mizar's SL Series competed against other "fast" reflectors from ASTRO, EIKOW, KENKO, TAK, & VIXEN for deep-sky film photography -- remember 35mm SLRs?
First Light was last night, and I did its final collimation, then a dozen or more star tests, starting with Arcturus. The 130 gave me one of the best of views of Venus that I've ever seen in one of my scopes. Ultra-sharp limb -- and the seeing wasn't perfect, with thin cloud stripes drifting across the field -- in the clear zones. Despite the Moon, I got some excellent deep-sky views, too.
Second Light, I'll compare the 130's star colors & resolution against my 1984 Tak FC-76 -- hopefully tonight.
