Hello,

 

I've got a question regarding the following two 25mm eyepieces.

 

Was anyone able to compare the TelVue 25mm Plossl and the ES 52° Series 25mm eyepiece?
If this is the case, what are your experiences regarding the optical quality of these two eyepieces. Moreover it would great to know which one works better when using glasses for observing.

 

I would use this eyepiece at a slow ratio telescope (>f/8).

 

Clear skies,
Patric

I have not used either, but based on the manufacturer-specified eye relief  (16.4mm for the ES, 17mm for the TV), I would not expect either to be exceptionally eyeglass-friendly.   Assuming the eye lens is not deeply set, 17mm gets me into the territory of being able to use the eyepiece with glasses, but typically too short for comfort. YMMV.

Yes very borderline for glasses. Either one could work depending on one’s eyes but it would be snug to get the whole FOV. Something like the APM 24 UFF is a safer bet for glasses and offers a wider view, although it is more expensive.

A Celestron Xcel LX 25mm which is 60° is a good alternative. It has enough eye relief for wearing glasses. Vixen SLV 25mm 50° is another longer eye relief option, both Celestron and Vixen are good optically.

thanks for your quick answers.

 

OK, The APM 24 UFF has got a really nice eye-relief, but the weight is already it little bit high for my taste (330g). I really like smaller "light weight" eyepieces.wink.gif

 

If I would say that the eye relief comes to second for my decission, what do you think would be the better choice in terms of the optical performance?

 

Clear skies,

Patric

 

Edit:

@25585: I will take a look at your suggested items.

The TV Plossls I have owned have been very sharp and deliver a little bit extra compared to $40 Plossl.

I have the Meade version of the Xcel LX 25 and it is excellent, and glasses compatible. Maybe 17-18mm of ER. It doesn’t sound like you need the excellent edge correction for fast scopes but hey it never hurts, and what is good at F5 is usually better at F10 or whatever.

I like the Vixen LVWs and enjoyed an older LV but haven’t used the more current SLVs. Certainly regarded as sharp, glasses friendly eyepieces. At $169 most would argue they are overpriced but I have sold a few brand new for $75 or so (I have a few Vixen scopes and these tend to come as stock eyepieces). Likely great eyepieces I just didn’t need them. Certainly could be a bargain under $100.

Hello Scott,

 

I assume you mean the Meade HD-60 series. Is the optical quality of the Meade HD-60 25mm version comparable with the TeleVue Plossls?

I have not used the TV but I did some significant research before I purchased a set of the Explore Scientific 53's.  They have good reviews.  Because of the weather I do not have much experience with the optics yet but I can say that the guild and finish quality are excellent.

I would say so. I didn’t ever compare them but I don’t think you would be missing out contrast wise with the 25mm Xcel or HD-60, and you get a wider view and maybe another mm of ER.

Hello,

 

based on your information I will give it some thought which 25mm eyepiece would be the best for me.

 

Thanks again for your answers.

Nice collection of ES 52° eyepieces

Have the TV 25mm, actually have 3 of them (don't ask how).

Wear glasses and never had a problem. The Paradigms/BST's I have are given as 16-17mm and I use those all the time. So from my experience 16mm eye relief is adaquate.

 

Sat here laughing a bit as if you go to the 32mm TV people complain of too much eye relief. So it seems you just cannot win.

It depends on if one wears glasses. For glasses a 32 Plossl has pretty much ideal ER. If you don’t wear glasses it can feel a bit excessive and can lead to eye placement issues. Some non-glasses wearers struggle with more than around 12mm ER but most glasses wearers need a minimum of 16.

Same optics Celestron Xcel LX & Meade HD-60 ranges. For the 25mm FL I use a pair of Meades when bino viewing. 

 

If you see a Vixen 22mm LVW for sale, get it! They are no longer made but have never been rivalled, though a 24 UFF comes closest.

If you don't find anyone with a direct answer to your question, I would gamble on the Explore Scientific 52 degree. I have the ES 30/52 and the quality of the view is superior to a generic 32mm plossl when used in an Orion Apex 127. I would describe the ES as almost 3-D and the plossl as sort of dull by comparison...Good luck with your choice! hmm.gif

People who have TV have no need for ES and vice versa, so probably not a lot of observers with experience with both. I have the TV and can tell you they are not generic Ploessls. They are sharp, high contrast, with excellent glare control. Of course, I have no experience with the ES.

OK, finally I have just ordered a Meade HD-60 25mm eyepiece. I think this item could be the best choice in terms of quality and eye-relief. wink.gif
