Quote:Since you mentioned Tele Vue, I must confess that if I had to do it over again, I would have done less experimenting with the other brands, and would have spent the extra money for a complete set of Tele Vue Plossls. There is not one Tele Vue Plossl I have looked through which has disappointed me. Special mention must be given to their 7.4mm, 8mm, 20mm, 26mm and 32mm units.

Quote:I agree with this. Often people are turned off by the price of TV, but you know what you're getting and you know you're going to like it.It can often be more expensive to "experiment" with other brands, than it can be to just get the EPs you want.

Quote: I can agree with this to an extent--especially for the TV Plossls, where the price is still relatively affordable. When it comes to some of the *really* expensive TV stuff (e.g. Nagler, Ethos, etc.), I am inclined to go for the "good enough" EP of another brand, rather than the top-o'-the-line and mucho expensive TV. I know that many disagree, and I can't argue at all with someone who really wants the best, but for me there is a certain price/performance tradeoff that will probably limit me to more modest EPs.
Quote: From what I've gathered, it seems that the differences, if any, are going to be minor.
Quote:In my SW Mak 180 Pro, the 15mm GSO Plossl is noticeably *better* than the TV 15mm. The GSO is sharper and planetary detail is more evident. This wasn't the result I wanted...

Quote:... reviews for cheap to mid-range EPs are ultimately more useful and important. You don't need a review to tell you that an Ethos is awesome. You do need a review to tell you how much of a compromise you are making by using a GSO plossl or an Orion Expanse or a Baader Hyperion, each of which fills a certain need and fits a certain budget.
Quote:OK...what would be the list of "budget" eyepieces you would consider best for such a review?? I'm not so sure I would mix price classes though -- in your example I would not consider a GSO Plossl and a Hyperion in the same league. However, things like GSO Plossl, Owl Enhanced Superwides, Owl Plossls, and maybe things available for a unit cost of say $35 or less might be an interesting thing
Quote:In TV's case, we don't know the exact design so can't produce the exact spot behavior since it is proprietary.

Quote:the GSO showed bloated star images within 15-20% of the field stop. It was noticeable but not really objectionable. Racking the eyepiece in and out of focus clearly revealed astigmatism at the edge.
