    Default define high quality eyepiece?



    Hi guys, I keep hearing that you need good quality eyepieces for short F telescopes but I've searched for a good while so forgive me if i missed what I'm looking for.

    What are good brands and what exactly should i be looking for since $ doesn't always mean that's what I'm looking for. So again what should i look for for a f4 scope?

    Thanks, Ken

    With an F/4 you may need to consider getting something like a Paracorr 2 as well as high quality eyepieces.

    Highest quality eyepieces are probably the Ethos series. But if you don't want the immersive view the choice would be the Delos series.

    Stepping down just a little (and some would say not at all) you'd be dealing with the Explore Scientific 100 degree series.

    Now things get really messy. High quality really becomes what you really like - and everything I said above and will say can be challenged depending on your particular needs and desires.

    But in your case you need something that will work with your F/4. For that purpose you need to look around and to define what you want. Some that come to mind would be the Naglers, the Panoptics, some of the Pentax (I think it is the VW series some think are the best ever), I'd probably check to see if the Zeiss Abbe Orthos will handle that speed, I know that I'd be thinking about the Siebert Orthos (since they are supposed to handle down to F/3.3), etc.

    You'll have to explore. And the best way to do that is to go to a star party where a lot of people have fast scopes and see what they look like in your scope (unfortunately, not all of us have that as an option).

    What telescope do you have? Whether its f/4 or f4.9 could very well determine if you need a paracorr or not.

    I have four of the Siebert 60 degree Orthos, and have used them in a 16" f/4. Perfect from edge to edge.

    I use the Siebert Orthos with a binoviewer for observing the planets and globular clusters with two 6" refractors working at different focal ratios. The build quality is solid, and they are light weight which is an added plus.

    Panoptics word decently without a coma corrector, and really well with one. Hyperions are fair without the CC and good with it.

    For coma correctors, the Televue Paracorr 2 is the Cadillac and is priced accordingly. The Baader MPCC has a good reputation and is roughlt half the price.

    Expensive EP's are better corrected, among other things, to handle faster scopes than other "bargain bin" brands, therefore priced accordingly. For example, a well made name brand EP will perform much better than a home made EP of the same type. But even some of the most expensive EP's need help to correct coma in a F4 scope. That's why there is a niffty little tool know as a paracor. Mitch named a few of the better known brands to handle a fast scope. Just my 2 cents.

    I use to think TeleVue was the best until I viewed through a Leitz 88 degree, and a set of Nikons eyepieces. I still have have a few TeleVues, but there are better eyepieces out there if you want to pay the price.

    This is true, at f4.5 the scope may not need a coma corrector with good EPs. But F4.0 may be be another story.
