[Re: snowboycosmos]       #5512170 - 11/09/12 07:04 PM Edit   Reply   Quote Quick Reply   Hey Snowboy . . . , I found a used Denkmeier S1 - it's a permanent fixture on my CPC1100. One eyepiece and I get 3 different views - based upon these focal lengths: w/ reducer = appx 1764 mm w/ a 23 mm EP = 77x normal setting = 2800 mm w/ a 23 mm EP = 122x @ barlow setting = 5600 mm w/ a 23 mm EP = 244x Change EP's and get a whole different set to powers . . . pretty neat!! Before you buy anything - check the used market! The Denk Powerswitches are really the best! Regards, Bob Post Extras:       snowboycosmos member Reged: 07/18/12 Re: what focal reducer should i buy?

Is it the short version or the regular? Silver coatings ? I don't think I'll find a second hand one here in the uk but will have a look. If you see one anywhere online do let me know.. Will it work ok on the CPC'S with my WO binos? Many thanks for the info... Snowboy Post Extras:       JoeR Pooh-Bah Reged: 03/07/10 Loc: Columbus, OH Re: what focal reducer should i buy?
