I was looking at ordering a Seibert 9mm ultra for my 11 inch sct. Just wanting to know what thoughts anybody has on the Seibert eyepieces. I was hoping to purchase a ES 92 7,8, or 9mm whenever they come out, if ever.

Generally people prefer the six element ones in fast scopes but shouldn’t matter much at F10. I don’t remember if the 9 is four or six elements.
