inexpensive 30-35mm Plossl for eyeglasses use new
      #6137895 - 10/14/13 09:31 PM

Hi everyone, I'm looking for a Plossl to maximize the TFOV and exit pupil in my 60mm f/11.7 cheapie scope and allow glasses use without touching the EP. Many 32mm Plossls like my Meade 4000 have the eye lens so deeply set to avoid the blackouts that they are unusable with glasses on, but apparently some aren't.

Specs of usable ER for Plossls are apparently not much of a demand item, imagine that! Anybody used or know of Plossls for eyeglass use?

The Vixen NPL 30mm plossl might be what you are looking for. It has a 2-position twist up eye cup which gives a bit more flexibility. The optics are great for the price as well !

It would be interesting to know what the average price of an eyepiece actually is.

I use my Meade SP32 also and noticed the same thing, so now I just fold down the eye cup and it made a noticeable difference, now I can see the edge of field of view with my glasses on, though I don't know how well this will work for you.

OK, I'm no expert with Microsoft Excel but using the "2013 Buyers Guide to Eyepieces", I came up with an average price of $190.58 out of 973 eyepieces.

+1 "The Vixen NPL 30mm"

Or a Vixen NPL 15mm with Barlow. Very sharp ep and enough eyerelief. Also good when using in daylight or with a H-Alpha solarscope.

I use glasses, and have the 30mm NPL and 32mm Omni. Both are usable, the Omni has more usable eyerelief. In fact, with the Omni, you do not even have to touch the eyepiece with your glasses to get the full FOV. The NPL requires me to rest my glasses on the eyepiece. Both provide similar views.

If you're handy, try the 34 mm Plossl described in my signature block. Only hand tools neded. It can also be found (with a few errors) here on CN.
34mm Plossl. The cost should be less than $35 if you don't have any discounts. Eye relief is quite long. Works great on SCT scopes (large f-ratio). Has filter threads. I can use my glasses with it if I care to.

The TeleVue 32mm Plossl bought used would run in the $80 range and though not truly inexpensive, is probably the best choice. It is very comfortable to use with glasses on. Another option for use with glasses is the Edmund Scientific 28mm Plossl. It is cheap but it narrowly misses out on the focal length requirement.

IIRC, the Edmund 28mm RKE is actually 28.7mm, with eye relief in the 24mm range.

I still think that the 32mm TV would be the best choice.

I was referring to the Edmund Plossl 28mm, which is different than the RKE 28... See here.

I know - Have you tried both, and if so, do you like the Plossl better?

The Edmunds 28mm Plossl is nice and has around 22mm ER I believe and lens mounted high. Not fully multicoated though, or in the FL range you want but a very nice performer!

The 30mm Plossl from Surplus Shed looks to have a high mounted eye lens. Give them a call to validate...they usually are good over the phone helping out.

30mm Plossl

Set 3 Plossls (better view of 30mm)

31mm Eyepiece (3 elements and 35mm ER)

Consider a GSO 32mm plossl.
Very eyeglass friendly.
Retailed under many different brand names.
Very affordable new, and even more so used.
I paid $20 for my last used one, shipping included.
They look like this:

I think thats a little low for the cost of a used TV 32mm plossl. In the last 60 days, sales of this eyepiece on Ebay ranged from $95-120 less shipping, with the average probably around $110.

I think $85-$90 might be the average, but keep in mind I am shooting from the hip. With that being said, I watch CN Classifieds and Astromart like a hawk, but not eBay. The three that I have owned over the past 18 months I paid: $85, $75 and $75.

Thanks for all the suggestions, everyone! The TV Plossl, while the best, is probably overkill for this application so I'll be looking at the Vixen, which looks good, and the Omni. In fact, Bob's comment that you don't even need to touch the Omni to see the full FOV is exactly what I'm looking for.

Bill, The 30mm Surplus Shed EP looks nice from the photo, night and day difference on where the eye lens is set compared to my Meade.

Izar, I've looked at that GSO Plossl a number of times online but can't get a photo to see how recessed the eye lens is.

Ron, that looks like a project for me and Little Zealand #1, especially since you can buy the pair of doublets for the EP ready-made. This is very intriguing as I used to be a DIY person and have fallen off the bandwagon since having kids. This looks like fun…

Hmmm now I have too many options, such wonderful "problems" to have…
