Which 3 of your eyepieces get the most use, and why?

I'm more imaging than visual but I do like to view every now and then. People generally don't like them but I find my WO 9mm swan gets most of the time, super sharp and contrast and works very well with a Coronado PST for solar. Also have a Meade 8.8mm uwa though it's nice and is good for eye relief doesn't get as much time. Next would be the Vixen 30mm npl. Haven't had a chance to try the 3.2mm BST but suspect it will be good. As you can see I haven't settled on one brand.

Wondering whether a Televue 32 or 20mm plossl will be worth the extra cost?

I have a set of Delos/Naglers and SLVs plus some plossls other stragglers and I would say although I use many of them over a period of time my most used recently is probably the 17.3mm Delos.

I use a pair for binoviewing and I only use 1.25" eyepieces on smaller scopes so it is often my wide field eyepiece in small scopes unless I use something with a smaller apparent field of view to get a slightly wider true field of view.

If I did use 2" eyepieces in smaller scopes then my 22mm Nagler might be in the running.

Quite often I got from 24mm ES 68 degree to Nagler 13mm T6 to 4.7mm ES 82-degree. That's for "general" observing, as they all have wide fields and I'll most likely be using an alt-az mount, and all have pretty good performance.

For planetary or lunar, it'll be any three of my Baader Genuine Ortho's, or perhaps throw in my 3.9mm Siebert Starsplitter for high (power) kicks!

2 weeks later ......

My most used 3 eyepieces are none of them, due to the cloudy conditions that have persisted since Dave / @F15Rules posted his pic of rainy Lincolnshire :rolleyes2:

But "Clear Outside" is promising me 2 clear nights in the coming week so my fingers are tightly crossed 🤞🤞

Clear outside has been promising clear nights but for the last 12 weeks I had nothing, tonight was supposed to be clear and at 5pm looked promising but as the time went on the clouds have rolled in once again.

Have been more fortunate this side of the UK, as last night (and tonight) was windy yet clear. Based on last night; 6mm Ethos, quite sublime on M35, 21 Ethos for just panning around and generally picking up clusters, early doors; 7mm DeLite (or possibly 5mm) for Jupiter.

Hi all, been AWOL for a long time, happy to be back. Hoping to take the 20" out tomorrow night. I have the APM XWAs, 9, 13 and 20mm, plus a 17.5 Morpheus, a 28mm LET, some plossl pairs, (25mm/32mm and 40s for my binoviewer). Also a 10mm BCO and a 31mm Baader 2".  I had a few Ethos but was afraid I'd drop them or lose one out in the countryside. The 21mm Ethos is awesome as you'd expect, but I got the three XWAs for what I sold it for. Also had the 13mm. Superb. The XWAs aren't far off in my opinion, even after side by side tests. I can tell a slightly narrower FOV with the 20mm XWA vs the 21mm Ethos, but... it came down to money as always.

I only have one 2" filter, (OIII) so my Hb, TV Nebustar, UHC and small OIII filters are all 1.25" which means I have to use what's available in the 1.25" filter range depending on what I'm looking at and exit pupil.

So long story short, I love the XWAs, 9/13/20mm. One of my dobs is f4.5, the other is f4, so for faint DSOs I try to find the right mag with an exit pupil around 4-6.5mm. 

Observing galaxies don't require filters, just dark skies, so enough mag vs decreasing exit pupil becomes the name of the game for me.

Yep I've only had one chance to observe since this thread was started, with my new mount so that I could even observe at all ! I expect when I actually remember that I have a Carl Zeiss Jena Ortho 10mm, that it will probably become one of my favs.

Ooh interesting question this one, let's think. 

Dob, probably the Nikon 17mm as it covers so many bases (exit pupil and fov) and as it has a supplied EIC it doubles up to a 14mm. Cheating maybe yes but it is bought and supplied as one eyepiece.

In my refractors it is a zoom, I think the 7-21 gets most use and love it for doubles and clusters.

My large bins I have a pair of 18mm APM for them which again are the size that fits most Dso (magnification & fov). (Its two again but the same size count as one for the purpose of this answer)

Right now, it’s the Pentax XWs 10, 7 & 5. They  are fantastic eyepieces and work brilliantly for WL solar in the 3” frac - I’m doing much more daytime viewing than night observing currently. I’m finding I can really hit the seeing conditions with these 3, giving 57x, 81x and 114x respectively. Can’t recommend them enough.

I tried answering this thread before and ended up listing all my eyepieces 🤣

But now I have a Solar Scout, so the picture has changed. 

Eyepiece 1: Ha Solar: Vixen NPL 30 mm

Eyepiece 2: Dark sky trips: Vixen NPL 20 mm

Eyepiece 3: White light solar, lunar, planetary, DSOs, doubles: Explore Scientific 6.7 mm

Now that my EP collection is wider, my answer is completely different. Low mag/wide-field: 2" 20mm StellaLyra 80°. Medium: Baader Morpheus 12.5mm. High (if seeing allows): Pentax XW 5mil.

However, I love the Morph so much that I often start with that and return to it after trying other mags.
