I got a made-in-Japan Orion variable-polariser, way back when. I finally saw the festoons and whorls within Jupiter's equatorial bands with the polariser, through my Orion "StarBlast 6" OTA from 2012, nigh tack-sharp, perhaps too sharply, if such were possible. The event occurred round 2015, and during a few moments of excellent seeing.
Even at round 180x, the Newtonian was collecting too much light, with Jupiter still washed-out, a greyish-white orb, no detail whatsoever; still with the four flares caused by the spider-vanes, jutting out from the planet, but somewhat shorter at that higher power. It was at that point when I integrated the polariser. The view appeared as a NASA television broadcast, that is, on a 1960s CRT colour-console.
Yesterday, I opened a case with PayPal to get a refund on a backordered ST80 OTA. I've got until the 10th to change my mind. If not, I'll get an Omegon.
