D&G does make great optics but historically they have been VERY reluctant to tackle good, moderate or faster f/ratio achromatic lenses where Jaeger's has not. I and a few others have certainly heard/known of a few mixed quality reviews of the speedier Jaeger's objectives (in the 6" class particularly) but what I've seen of each of several various examples in all f/ratios was that quality was exceptional in each case! So, ha ha ha! ;-)

So, ha ha ha! ;-) I've seen some very good (excellent, actually, though my personal tastes in refractors are more toward apos than achros) Jaegers objectives in telescopes. And I've seen some fair ones. I've never personally seen a BAD one, so I refrained from commentary within that context, and left out the stories that circulate OUTSIDE my personal experience. I would still characterize the overall highest PERCENTAGE of excellent achromatic objectives as likely to come from D&G, though I've certainly seen excellent examples of Jaegers' objectives as well... Perhaps the reason we don't see many D&G scopes with focal ratios below f/12, is because they are committed to producing uniformly high quality objectives consistent with their reputation, and realize that it's not easy to consistently deliver the quality they're committed to at shorter focal ratios, especially in the price range they work within... Regardless, I sure wouldn't buy ANY telescope, or objective, on E-Bay... -- Jan Owen To reach me directly, remove the Z, if one appears in my e-mail address... Latitude: 33.6 Longitude: -112.3

So, ha ha ha! ;-) Honestly, quality matters little in a 6" f5 achromat. Residual SA and horrific CA completely limit magnification so it is nothing but a big rich field scope. You don't need superb quality for that task. -Rich
