Lets talk about eyepieces for a bit. Whats your most used eyepieces and why.
For me under my garbage skies most of the time something in the 13/14mm is the best I can use with my 10 inch or 16 inch. In my SCT its runs between a 20mm and 32mm and in the frac… well I don’t use it enough to know which are the most popular yet, but i would guess its like a 6 or 8mm. Whats everyone else got going on in their world
Of course, it depends on what you’re looking for, where you’re at and what you’re doing, but I’d say the one EP that I use the most is my Meade 20 mm. It’s part of a 5 piece set I bought when I bought my first scope and it’s what I start out with no matter what I’m doing or what I’m looking for. It gives me a good FOV, nice clear view and makes it fairly easy to find whatever I’m trying to find.
I know quite a few guys with dobs in the 10 inch to 16 inch range and we all use 13/14 and 20/21mm eyepieces the most. There is something about that focal length that works for us.
Yep, I have a 14 inch dob these days. When I first bought the Meade set of EP’s it was a set of 5 and came with an aluminum case that holds 9 EP’s. It’s full nowadays. I got that set in, if I remember right, 2001. Of course, since then I’ve accumulated a bunch more. But, when I do a public star party like it was Friday night for my local library, I don’t bring out the high priced ones. And we had about 65 people there and the only other scope that was there was a 4.5" tabletop dob, so pretty much everyone wanted to look through mine!! LOL I don’t think I even took the 20 out til I broke down the scope to go home!! But, as far as I could tell everyone had a blast. They all loved looking at Jupe and the moons!!
We were actually there to look at the Worm Moon for a project the kids were doing at the library. I tried to tell them when we went out to look at the spot they wanted to have it at that we most likely wouldn’t be able to see the moon very well until it cleared the trees!! Sure enough, there were enough trees that the only time you could see it was while it was going through the fire lane. It finally got over the trees just about the time I had my scope loaded up and started home about 10:30. Ah well!! 
That depends on what I’m looking at and what scope I’m using . In my 5” refractor , I usually start out with a Meade Plossl of 9,7mm or 12.4mm on Jupiter and Saturn . That yields like 90x to 120x magnification . Thats my typical starting point . If seeing supports it , I’ll push the magnification accordingly . I might 2x Barlow a 15mm on Mars for starters . That gives me about 150x magnification in that scope . If I want the entire Moon in the FOV I’ll go probably with a 20mm Plossl at about 60x magnification and go up from there depending on what part of the moon I want to get closer in on for exploring craters and mountain ranges or cruising the Terminator . I have a 6.4mm Plossl but rarely use it unless I really need it for a high magnification situation . That yields about 180x magnification on this scope . That can come in handy on Mars (seeing permitted) , though I’d rather Barlow a 12.4mm or a 15mm due to the short eye relief on the 6.4mm Plossl . Magnifications are all over the place when it comes to various DSOs but for a full view of a large object like the Andromeda galaxy , I’d go with my 32mm Plossl which gives me about 36x magnification and the full galaxy pretty much fits in the 52 degree apparent FOV with the light grab of a 5” scope . That scope has a focal length of 1180mm .
Now with my 8” Schmidt Newtonian , it’s a whole different animal . At f4 the focal length is only 812mm , so I find I use the Barlows a lot . I have a 2x and a 3x Barlow . It’s inherently a wide field scope so Barlows are a must for any kind of magnification on Planets or small DSOs . On the Andromeda galaxy I’ll use my 26mm Plossl and that yields a magnification of right around 31x . The galaxy spills past the apparent 52 degree field ever so slightly with 8 inches of light grab under a good dark desert sky . I can track that object for hours or all night while I track a Planet with my refractor . I get a full Moon in the FOV with a native 12.4mm Plossl in my Schmidt Newtonian or 2x Barlow a 26mm Plossl . That gives me about 65x and 62x magnification respectively . Using the double and triple Barlows gives you lots of magnification variety so I can really fine tune magnifications to seeing conditions with the seven different focal length Plossls I have . Meade 4000 Super Plossls ; 6.4mm , 9.7mm , 12.4mm , 15mm , 20mm , 26mm and 32mm .
With the super short eye relieve on the 6.4mm , it’s probably my least used eyepiece unless I go extreme on my 8” Newt with a 3x Barlow under it which gives me a maximum magnification of 380x on that f4 scope . And on the 8” Schmidt Newt your eyes need to be fully dilated to use the 32mm native or you’ll see the shadow of the secondary mirror due to the large exit pupil . I don’t even know if I can get 7mm out of my fully adapted eyes anymore .
Bottom line is that I use pretty much everything I have including my Moon filters , various colors of Planetary filters and the 4 types of Nebula filters I have . I also have a Baader semi apo filter that works great in the refractor for Jupiter and Venus .
The Meade 20mm Plossl is a nice piece .
I like mine a lot .
65 people would be a huge outreach night for around here. Its been a hot minute since i have been to one
I use that eyepiece in my Lunt 40mm solar scope from time to time
My 4 inch frac is used mostly for solar work these days and its my travel scope. I have a travel set of eyepieces that run from 3mm to 40mm. I would suppose that the most used in that set would be the 9, 12.5 and 18mm. When i use it at home for solar work it see a 12 and 18mm, at night i switch to my ES 82 degree eyepieces. Seems like the 4.5/82 and 6.5/82 find their way in there a lot.
It depends on which telescope I’m using. For my 10” f/5 I usually start with my Televue 24mm Widefield. If I’m using it in my light polluted backyard I rarely go above using a 9mm Nagler. At one of my dark sites I can go down to a 4.8mm Nagler with a 2.5x Barlow. I use my 6” f/8 for lunar and planetary, so I can use higher powers. I have a set of UO orthos, and sometimes I can use my 4mm ortho.
20mm is mostly used, it depends, and higher magnifications for planets. I don’t have a lot of eyepieces, still only two 
Those are rookie numbers, need to pump that up a bit lol
I’ll go as high as atmospheric disturbance allows without image degradation . As soon as I see any kind of image degradation , I’ll pull it back one step .
Yeah of course, I am hoping to invest on some.
I do the same thing. I keep hoping to make it to 200x, it doesn’t usually happen lol
It’s certainly better to be a bit under magnified than over magnified . As soon as detail starts to blur even slightly you know you need to pull back . Even with great seeing I rarely get a good Jupiter past 120x . Only occasionally 150x or so . I get better on Saturn for the most part which is kinda strange and it makes no sense , since Saturn is farther . Another example would be Mars . A harder nut to crack that Jupiter or Saturn and it closer . And Unanus or Neptune both easier to get a good image than Mars . Strange phenomenon I guess .
I have had one night that i was able to sit on Saturn at 400x. It just stayed in focus with very little atmospheric interference to mess up the image. I would take that again in a hot second
I got lucky with two nights in a row like that with my f4 Schmidt Newtonian . I could only get to 380x with a 6.4mm ocular and a 3xBarlow under it . Probably could have gone higher if I had the glass for it . I made a sketch of it with 7 moons in the FOV . Just amazing . Never been able to repeat it .
Being able to get that high here is a fluke, i wouldn’t complain if that happened more often lol
Same here . It was a lucky night . Couple nights . The thing was huge in the eyepiece . Never been able to push that power on Jupiter .
