If you were to do an eyepiece/equipment purge, which would be the ones to stay & which ones would go?

 

I've already let go of the following, though some have given me seller's remorse bawling.gif

 

Pentax XW 30

Explore Sci 8.8mm 82° 

Vixen HR 2.4mm

TeleVue 26T5 Nagler

Baader Morpheus 17.5

 

Of my current stable, I think I would get rid of:

 

Explore Sci 14mm 100°

TeleVue 4mm DeLite

Baader ClickLock Dielectric diagonal

 

and if I had to [remorse would be likely]:

17T4 Nagler

ES 9mm 100°

Of the eyepieces that I currently have, if I need to purge the following might go:

 

ES 17mm 92

Delos 17.3mm

Pentax XW 10mm and 7mm

Panoptic 24mm

 

There is nothing wrong with the above eyepieces at all - they are very fine performers in fact. Its just that they dont seem to get much use given the other eyepieces that I have shrug.gif

I pretty much sold or gave away all the eyepieces I didn't want to keep. I do have one

straggler: an ES100 9mm. I bought the ES120 9mm last year and also have a 9 Morpheus

plus the 8 & 10 Ethos so that range is well covered.

I messed up and bought a Nagler less than a year ago.  Now I have 4 Naglers and 24 Panoptic.  I will soon be purging all the other junk I wasted my time and money on.

If it brings you joy, then it's not junk and you haven't wasted your time & money. It's just a vessel for bringing the light into focus laugh.gif

Very true.  Calling something junk that allowed me to see the wonders of nebulas and star clusters might have been a bit harsh...  but then again junk is still fitting for a few of the ones I will be letting go!

Of my current stable, I think I would get rid of:

 

Explore Sci 14mm 100°

Of the ones I've owned (20, 14, 9 & 5.5mm) the 14mm was definitely the best eyepiece. Careful there.

 

 

Of course purge begets binge begets purge begets binge.... Ad Infinitum.

Haha touche' lol.gif I like the 9mm the best out of the ES 100's, but the 14 is pretty good too! It's just one of those that gets overlooked because it's in between the 12mm & 17mm 92°.

I keep a list and there is a complete ranking system. I called it the 'Expendability Rankings'. Those that float up to the top of the list are culled when funds are needed. 

 

In your case, I would NOT get rid of the Baader ClickLock Dielectric diagonal! That is an excellent diagonal and unless you replaced it with something better, I can't think of any reason to part with it. Think of it, you use it with every eyepiece; it is definitely more important than some extra eyepiece you may have that is there just to fill a gap.

Since I bought my current set of eyepieces I have a considerable number that have become redundant. I'd probably do well to sell them off but, given what i'd expect they'd fetch, I'm not sure I want to bother packing them for shipment. So, I keep them. Maybe someday I'll run across some beginner who could use them. Maybe some day I'll grow tired of storing them and list them.

I've done my share of buying and selling and buying and selling,

and I think I've arrived at the point where everything I have is worth keeping.

 

It's a feeling of...satisfaction.

Recently purged the following:

 

  • 7, 9, 12.5, 18 Fujiyamas
  •  8, 11 TV Plossls
  • 10 BCO
  • 7 Nagler T1
  • 12 Nagler T2
  • 50 GSO SuperView

 

If I absolutely had to do another round of purging:

 

  • 9 "gold line"
  • 28 RKE (though I still use this from time to time to get big exit pupil with small AFOV - great for keeping bright stars out of the field when trying to hunt for dim PN)
  • 10 Ultramono
  • 11 DeLite (I love this eyepiece, but don't use it much since I have the Docter, and now a binoviewer for the moon)

 

If Explore Scientific ever gets more 92s with the focal lengths I want, then I'll likely standardize on those and get rid of the following:

 

  • Docter (would buy the 12 ES92 instead)
  • 8 Ethos
  • 6 "gold line"
  • 4.5 Delos
  • 3 Delite

 

If ES doesn't get more 92s in the focal lengths I want, I have some thinking to do.

Hmm. Of my own I think the Orion LHDs (14 & 20) as I now have ES92s. ES62 26mm as I have a Meade 25mm HD 60. 

 

Also Nikon NAV SW 10mm as the Pentax 10mm XW is so good. Some duplicate eps from bino viewing pairs.

 

Some cheapie but OK ones like the S-W LET range, excess Plossls that came with scopes. But those are almost giveaways really.       

 

There are some awaiting deeper evaluation, but the above are in most danger, just to cut numbers down.

I’ve been buying and purging for a long time, which is really the only way to learn what’s best for your telescopes, skies, eyes, etc. My eyepiece case is now a fully optimised, purge free zone. grin.gif

In the past I tended to experience more "churn" with my telescopes than with my eyepieces. Although both have slowed down a lot in the last 5 years or so. I have sold a few telescopes in my life but I really haven't sold many eyepieces - only one comes to mind: a Tele Vue 20mm Plössl. I always regretted selling it and I have since bought another one (my "Keeper"!).

 

My eyepiece collection used to be best described as a "rag tag fugitive fleet" of okulars. In 2016 I actually put some thought into it and built a core "set" that I have been using ever since (TV 20,15,11,8 PL + KK 6 OR). The low power end has changed a bit over the years but for the most part I'm happy with what I have and feel no need to purge.

 

As for past purging, all my other eyepieces that I've jettisoned have gone either to my 16 yr old son (who has several telescopes now!) or to friends. I do keep a couple of spares kicking around for outreach (not because they are less expensive, but because they have better eye relief and wider fields than my Plössl collection).

 

I always do try to walk the middle path - keep it simple, keep what I want/need, and enjoy my hobby. I have finally found that balance for me. Everyone has to do what works best for them.

 

Cheers!

 

Rick

I do keep a couple of spares kicking around for outreach (not because they are less expensive, but because they have better eye relief and wider fields than my Plössl collection).

 

 

That's my general philosophy.   When I buy a new to me eyepiece, generally it's not contingent on selling the eyepiece it may replace.  So I tend to keep the older eyepiece because it was generally a good eyepiece, I'd rather have the eyepiece than whatever money the eyepiece might bring.  

 

But I also think an eyepiece deserves to be used and so if some friend or just someone seems like they could use the eyepiece, that's enough incentive to just pass the eyepiece on to someone who use it.. 

 

And I am glad your son is interested and involved, passing on one's passions is a bond... 

 

Jon

I recently purged all of my EPs (ES 24 68,  ES 82 6.7, 4.7, Meade 8.8, SW 4mm) but one.  That one that remains is my least-used EP right now and the only one I can't use with glasses on. 

 

It would be gone already except for one thing:  it's the Meade UWA 5.5, an overachieving, glob-busting, Jupiter-killer of an eyepiece. 

 

If it goes (and it still could) it's going to take something special to take its place, and I really haven't seen anything out there that has tempted me enough to pull the trigger on it.

For glasses, the Baader Morpheus 6.5mm is worth it. 1mm more FL & 6 degrees less AFOV, not making that much difference.

Way ahead of you. grin.gif Two of the EPs that replaced the ones I purged were the 9 and 6.5 Morpheus, which, along with the 17.5 and 12.5 I already had, make a nice set.  The 6.5 is a little tight with my glasses but still doable.

 

I use a GSO coma corrector, so the 6.5 puts me at right about 200x.  I can Barlow the 9mm to get to around 300x.  I'm keeping the 5.5 because right now it's the only EP that gets me anything in between those two magnifications.  The only thing I can see in my price range that might suit my needs is a Pentax 5mm, but the 5.5 magnification is a "sweet spot" for me that's proving hard to give up.
