    Default Price of scope versus price of eyepiece



    I was kicking around the idea that a ballpark relationship should exist between the price of a telescope and the cost of a "good" eyepiece for that scope. The idea being that once the limitations of one part of the package determines the quality of the image you see that improving the quality of the other component is not going to help you to see a better image. A relationship may not exist for high end scopes and eyepieces because the third component, the physical and technical abilities of the observer may become image limiting, but for moderately prices scopes and eyepieces one could. Any ideas of what a good rule of thumb would be? My guess would be about 30% of the price of the scope you should be able to get an eyepiece that produces a scope limiting image.

    Yes the weakest part of your optical path is your cheapest piece of equipment, but cheapest does not mean price but quality which usually goes hand in hand with price but not always. So would you put a $500 Televue eyepiece on a hundred dollar scope probably not but you have to start somewhere. If your goal is to buy quality equipment start with the scope and move up from there.
    I love my Skywatcher 120, the views are great for almost APO quality optics. it came with some okay eyepieces that add to my modest collection. I have no plans on purchasing a scope over 2500 so my eyepieces probably match my selection well being they do not cost more than $150 per eyepiece. Most around the 80 range.

    All my better eyepieces work wonderfully and really improve the views over the stock eyepieces in all my scopes. Orthos to me are the best deal out there. Even the inexpensive ones are really good in my opinion. Sharp!

    You can certainly use better eyepieces to maximize the potential of "lesser" optics, but, the trick is realizing the point of diminishing returns. The opposite is also true.

    Another way of looking at it, buying a quality eyepiece up front means you probably won't have to upgrade them in the future if you upgrade your scope.

    I had a Celestron C 102mm F 9.8 refractor and paid $119.00 when they were on sale. I had 8 ES 68° and 82° eyepieces at that time. The longer focal length of the scope would allow the use of less expensive eyepieces. But the view thru the ES eyepieces was outstanding. Since then I have bought a used C9.25 SCT, and a ES 102mm APO refractor, and a TS 130mm F/7 APO refractor. I didn't have to upgrade my eyepieces. Buy the best eyepieces you can afford, it will payoff in the long run!!

    It is a bit more complicated. Optical elements even in cheap scopes now days are pretty good. The price point for budget scopes typically achieved by cutting costs on mounts, focuser, diagonal etc. Also, many of less expensive scopes, reflectors and DOBs in particular are fast and need well corrected (read expensive) EPs for good results. On the other hand more expensive Mak/SCTs due to slow optics can work pretty well with budget EPs. So, 30% of the scope price is not right way to approach it. However, you can definitely find good quality EPs in $40-150 range which would work well with any type of scope.

    Quality is a multiplier; the atmosphere degrades the view, the scope degrades it some more, then the diagonal, the eyepiece, and your eye .
    Improving the quality of any part of the chain improves the quality of the end result - but you'll still be limited by the rest of the chain.
    So while you probably wouldn't justify buying a very expensive eyepiece for a cheap scope, if you happen to have a good eyepiece already it'll still help you to get the most out of the scope - you may not get as good a final view as you would with a better scope, but you'll likely get a better view than you would with a cheap eyepiece...
    I agree with the advice that once you're sure the hobby is for you, it's worth building up a collection of good eyepieces; most of us eventually end up adding or changing scopes over the years, but a good eyepiece will work with most scopes...

    Being from Vegas, I'll double-down on Jerry's thoughts above.

    With an f/4.7 Dob being my primary DSO scope, I've settled in to one brand of decent eyepieces for everything, and have a "sock drawer" full of mix/match eyepieces gathered over the years.

    However, we have a conundrum when advising new folks who may, or may not, stay in the hobby. I was advising a new member this morning about eyepieces. His scope is very much a beginner's model that he'll obviously upgrade if this hobby "sticks to him". I have a difficult time suggesting $150+ eyepieces to someone like that. The scope would be his "weak link" anyway, and just one high quality eyepiece would be much more than the scope is worth. I ended up suggesting two decent, Meade 4000 series Plossls that will serve him well until he moves on in the hobby.

    Good question.

    I was thinking of this question as something a new user may use as a guide to the diverse world of eyepieces. For those of us who are working on their Nth scope, the idea of getting the best you can afford is appropriate because we hope to someday get that scope that will demand a high end eyepiece.
