    Default Meade 4000 or 5000 Series Super Plossl Eyepieces for Meade ETX 125



    Hi,

    I've just ordered my first telescope - a Meade ETX 125 PE.

    I am looking at purchasing eyepieces for it. I was wondering if the premium for the 5000 series Super Plossl over the 4000 series was worth it. I am initially interested in planetary viewing but anticipate my interests to broaden.

    Also, would it be worthwhile me getting a Barlow lens? I was looking at x2 lenses. Can anyone make a recommendation.

    Finally, I was interested in connecting a webcam to my telescope but don't know where to start. What webcams are suitable and what else do I need. Please make some recommendations.

    Many thanks for your help!

    The Meade ETX 125 is an extremely slow scope -- f/15. As a result, it will be much kinder to your eyepieces than a fast dob. The differences between eyepieces tend to be in the areas of spherical correction, coatings, eye relief, and apparent field of view.

    You don't really have to worry about spherical correction due to the slow focal ratio of your scope.

    You don't really have to worry about eye relief (as much) because the shortest eyepiece you'll likely get any use from is around 10-15mm, which even in a cheap Plossl design, will still give you a comfortable 10+mm of eye relief.

    That leaves coatings and AFOV as the deciding factors.

    All of the Meade eyepieces (both 4000 and 5000) have good coatings, so that's not going to be a differentiator as far as I know.

    That just leaves AFOV -- and I believe both the 4000 and 5000 super plossls have the same ~55-60 degree AFOV.

    In summary, I think you'd do fine with the Series 4000s.

    If you want to spend a little more and get some of the added benefits of the Series 5000, such as the twist-up eyecups, a 60 degree AFOV, 20mm eye relief, etc. then I think you will be very pleased.

    As for the barlow -- that depends on your eyepiece collection. With the long focal length of the ETX125, you will rarely, if ever, use an eyepiece shorter than ~10mm (.7mm exit pupil). And eyepieces longer than 40mm are hard to come by, so your longest eyepiece will likely be a ~30-40mm (2-2.5mm exit pupil). So if you were to get a 32mm and a 24mm, plus a barlow, you would get 16mm and 12mm "free", and preserve the generous eye relief of the 32mm and 24mm oculars. But, since those four focal lengths are likely all you'll ever need in that telescope, you may prefer to just get all four and be done with it.

    Good luck!

    Great thanks. I was looking the Tele Vue x2 Barlow. I was wondering if this would be suitable for my ETX125?

    Also I was looking at cameras and got quite confused about it. I'm not sure what is suitable for my telescope. I was looking at the Orion StarShoot Solar System Color Imaging Camera IV but alot of the reviews on Amazon said it wasn't very good for planetary imaging it was only good for Lunar imaging.

    Many thanks for your help!

    I personally don't think you need to spend the $$ on a Televue barlow. I'm sure it's a fantastic piece of equipment, but from what I've read, any barlow of reasonable quality will be indistinguishable from the TV barlow...especially in a slow scope, where chromatic aberration isn't a problem. The GSO 2x barlow gets good reviews, and I think would work just fine in your scope. It's fully multicoated, has blackened lens edges, and it's OK that it doesn't have any exotic ED glass in it; at f/15 you don't need it.

    As for the camera, I would recommend that you get familiarized with your scope visually before you attempt to add a camera to the mix. Astrophotography is not for the faint of heart -- it's not just hooking a camera up to the scope and then out comes these Hubble-quality shots. You need precise alignment, long exposure times, post-processing on a computer, and pretty deep pockets if you're going to go down that route. Just stick to visual work for now until you get some more experience under your belt, and then if you are still interested in AP, you will likely find yourself going for a dedicated, fast focal ratio photography scope on an equatorial mount. At f/15, that ETX will take hours of exposure time to get any good photos of faint objects like galaxies.

    Great thanks. I think I'll hold off before buying a camera.

    I think you're going to really enjoy those eyepieces...I love mine! My dad has an ETX125 and he borrowed my 9mm HD-60 and really liked it in that scope too.

    Yeah looking forward to receiving them. It worked out cheaper including shipping to buy them from HD-60 set than buying the 4000 Series set in the UK!

    Default Re: Meade 4000 or 5000 Series Super Plossl Eyepieces for Meade ETX 125

    I do not wish to take over this post, but since some good discussion about the Meade EPs have already been started here: I am considering purchasing the entire set of HD-60 eyepieces from Meade. How do they compare in general to other brands out there? I have Meade 5000 32 and 14mm now and love them in my 8 and 11 inch dobs. I also have several meade 4000 super plossls, and other plossls that do not seem to measure up to the 5000 EPs. So my experience with the basic premium 5000 series plossls has been good. Purchasing a whole set may give me more consistency, and par-focal conveniences, while affording a very respectable view. Should I look elsewhere, or are these new EPs worth investing into? My 11 inch is an older Celestron/Discovery dob f4.5 so a rather short mirror if that helps?

    The 4000s are good but if you want real quality , look for the Japanese smoothside versions , they are hard to find but worth it , it took me about a year to find the whole set
