Quote:Anybody else buy the 1.2x 2" 45mm clear aperture OCS for your Denk binoviewers? If so, how do you like it?
Quote:I got the 45 ocs. I have compared it to the 37 ocs but i couldn´t tell any difference in sharpness, they where both equaly sharp to my eyes. I bought it because i got a 30 f3,6 on order and the bigger ocs will capture more light from the steper lightcone
Quote:but could see the Full Moon dust light cone projecting on the black orriface of the 38mm clear aperture OCS, so I know for sure the 45mm clear aperture is receiving more light.
Quote:The previous Denk OCS was a x2 while the new 45mm, according to it's pdf, seems to be x2.3.How do we get to x1.2?gb.

Quote:Unsure with the new Denk binoviewers, but with the old Denk II dual arm power switch this 2" "Multi-Purpose" OCS yields 1.2x/1.8x/2.3x in a newtonian (and with an additional reducer powerswitch the lowest power yields 0.87x in LL mode).Ken

Quote:Quote:Isn't Siebert's similar, an OCS in front of a reducer... ng. Maybe, but the point is that to get x1.2 from the Denk OCS you have to have a Power Switch.Not everyone has or wants the Denk Power Switch but they might be very interested in a45mm clear aperture OCS on it's own, especially if it was x1.2 as this thread's tile implies.gb.
Quote:"This is what Russ Lederman posted on the Vender Forum (See he even refers it as the 1.2x):"Yes, but he finally clarifies it in the footnote.Perhaps it is just his marketing instinct to promote it's lowest possible magnification (in his system)since that is usually the holy grail of binoviewing.gb.
