Hi,
Which do you recommend? The 22mm ca of the black night doesn't bother me at all.
Are these three in the same optical quality category or is one better.
I am asking about the optical quality of the bino itself not the fact that there is a powerswitch option with the denk and earthwin and a powermag wheeletc. with the siebert.

In that case I consider it a tossup. They are both optically excellent, to my eyes.(I can only speak of the Denk standards, since I've not used the enhanced Denks.)

Never used the Siebert brand of binoviewers before.
But I have viewed through the Denk Standards and the EarthWin standards during the same night.
They were like twins. Neither,out done the other visually.
Same with the Denk II's and the EarthWin Dielectrics.
They are one in the same visually.
Mechanically, the edge goes to the EarthWin since they have
camber adjust diopiters rather than the screw type of the Denks.

Hi
I have the Black Knight 22 Bino and it is terrific. Harry Siebert makes excellent optical equipment and I unreservedly recommend his products. Also -- I have the Power Mag wheel and it is also an incredibly good accessory to use with the binoviewer. one ep with either 3, 4, or 5 mags. You might consider it an essential accessory. You would not regret getting Siebert equipment.
Hope this helps,
Howard

As far as I can tell from their advertising, the Earthwin binoviewer is the same whether it is purchased with their standard or dielectric diagonal.

You are right about the Binoviewers David. You get the same diopter adjust with either binoviewer.
The body's are the same.
The only difference in the binoviewer is the beam splitter.
You get standard coatings on the basic binoviewer and dielectric coatings on the Dielectric version.
