Ethos 6mm, 147x and the whole moon.
It is a wonderful thing to see the entire Moon fit into a field of view at such a magnification; and in high definition, to boot!

I've a C8 too and I've used KK vulcano top othos 5,9 and 12,5 , now I'm 53 and cannot use anymore the 5mm because of too tight eye relief, I've changed it for a TS hr planetary eyepiece that once flocked give show me exactly the same tiny details (for this I'm gonna buy the 6 and 7 too), of course much more confortable too.
I've a Siebert Star splitter 6.4mm too but it add a warm tone to the image and for the Moon I don't like it.
Anyway when budget will allow me I'll go for Delite eyepieces

My highest mag eyepiece is a 4mm radian I picked up used, I use a 25% moon filter with it, I'm going to pick up a Barlow of some sort as my scope eats up magnification when conditions are good.

Every time I use one of my Delites on the moon with the 8", I get chills up my spine. Even during tonight, with its ordinary seeing, contrary to the weather forecast and the jetstream forecast, naturally. Even my mum who is a novice, was shocked at how good the moon looked.Too bad the moon wasn't around a couple of weeks ago when I had some darn near perfect seeing. I ordered a couple of Vixen HRs, I've always been curious about those, but I might be out of luck unfortunately as they are suddenly listed as "unavailable". The vendor will let me know on the status of these.

6” f6. I tend to use either my vixen 6mm or an old 9mm celestron ortho. No idea what the magnification is. I just use whichever is clear.

I have very good, crisp and contrasty views using a 12.5mm kellner eyepiece that I use with my F20 8 inch maksutov. I also enjoy using a celestron 35 mm eyepiece for low power views. Both serve well. Regards Larry

I was looking for some insight on what EP/scope combinations others prefer when viewing luna when I cam across this thread. Instead of starting a new thread I thought I might build on this one.
I recently added some new-to-me eyepieces to my arsenal; those being Naglers 22T4 and 17T4 plus an APM-84 12.5mm. I already have the range of Pentax XW from 20mm to 5mm.
Now that comet Neowise has done its thing I thought I would turn my sights back on luna and test my newer EPs in my 10" dob. Unfortunately last night I discovered that the shrubs on the south side of my dobs had grown tall enough to interfere with my view of the ecliptic. Today I started to do some major thinning and height reduction of those shrubs.
What I did discover is that the views through the Naglers were very clean but the magnification was low (without a barlow). The APM 12.5 shows a distinct yellow fringe and although quite comfortable that colouring was not what I had hoped. My Pentax 10XW was very clean and filled 80% of the view.
My next night out will be a comparison of my EPs to see if I have a preferred EP/scope combination. I am surprised I have never done this until now.
Pentax XW, 20, 14, 10, 7, 5
2 X Barlow
I secured the Stellarvue for wide field views, and that is how I will continue to use it. The moon is just too small in the SV80 for my liking.
I keep coming back to my Earthwin binos. Binoviewing the moon and the planets is just too comfortable. This week I have sort of settled on the the binos in my 10" dob, using my pari of 24Pans and now a pair of Pentax 14mm EPs.
I view at the EP without eyeglasses, but need my glasses to sketch. The eye guards of the Pentax EPs can be dialled down to accommodate glasses for sketching, but the 24Pans do not work quite so well for me. Perhaps removing the eye guards completely on the 24Pans while sketching will accommodate my sketching needs.
This week I will have to try the binos in my 16".

This morning I tested the binos in my 16” dob. Great views but my observing chair is not tall enough to allow me to sit and observe. I will have to get back on that project of building my cat’s perch chair.
removing the eye guards on the 24Pans did not provide any advantage over rolling down the eye guards

My favorite eyepiece for the Moon or planets is my 8-24mm Zoom. Because observing either is an exercise in patience with the ever changing seeing conditions, I like the ability to quickly zoom in or out to find what magnification works in any given moment.
I also use my smartphone camera as an "electronic" EP screwed directly onto the eyepiece when viewing with a small group of people, many of which have a difficult time finding the best eye placement and feel the need to grab the scope in order to look through the EP. Given that I use a manual Alt-Az mount, it doesn't take much for the object to be pulled out of the scope's FOV.
Well...that, and I hate constantly swapping out EP's. DSO's are an entirely different matter.

Scopes : my refractors ED and Achromat
EPs: Pentax XW 10 and 5 mm, Nikon Nav 7 mm SW and Baader Classic Orthoscopic 10 mm with Barlow X2 Shorty Plus Orion (Japan, the same of Ultima)

Always go to my ES82 - 4.7mm. Gives me 255x and about 1/3rd of a degree.

I use a TOE 4mm, however I find a moon filter makes for the best views whatever eye piece I select.

Well, it would depend upon which telescope I'm using at the time.
With my 101mm f/5.4 Tele Vue refractor, without using a Barlow lens, it would have to be my 3-6mm Tele Vue Nagler zoom to produce a not-so-high magnification of 180x with an exit pupil of 0.56mm. I would probably opt for my 4.5mm Delos, however, for a more comfortable view at 120x.
When using one of my medium-sized Dobs, a 10" f/4.7 Sky-Watcher Collapsible Dob, I like my 5mm Pentax SMC XW that yields 240x.
Five-lens-element Explore Scientific 70-degree eyepieces work quite well in the Naylor Observatory's 17" f/15 classical Cassegrain that I use fairly often for lunar observing. I usually use a 25mm (259x) or a 20mm (324x) but have gone much higher on occasion.

in my 6" 750mm fl scope, my most often used with monoviewing was the 12mm Dual ED(62x) eyepiece. Not a high power view, but gave an image of the entire globe at once. Now that I binoview, I use a pair of 15mm Dual EDs(100x) for that view. Both are considered moderate power though. For high power I currently use a pair of 6.5mm HD-60s(231x).
I haven't yet made a determination as to which I prefer in my 80mm 900mm fl scope.

With my small 6" F/5 achro, which is no way a Moon-Watcher telescope,
I like most the Pentax XO 2.5 with the Solar Continuum filter (540nm, 10nm bandwidth).
This gives me a magnification close to 300x for the details, rimae, ejectas, catenas of small craters, etc.
