I guess, for me, aperture still rules. My favorite is the 10" Dob. I have an interest in the shape of the mountains and crater wall shadows, well perhaps lunar shadows in general. The 10" lets me observe some details that smaller apertures aren't capable of. The fact the 10" is the largest scope this seventy year old body can haul around has, of course, nothing to do with it.

being my first and only scope at the moment...
and the first real scope ive ever used to look at the moon....
my 4.5" Meade newt!! lol
and with my new barlow i can get wikked close! 
But i did look at Selene with a Questar scope once.. and i knew from that day... one day, i must own one!! <3

My NexStar 9.25 inch f/10 SCT, as it allows me to use my binoviewers without having to rely on any relay lens. The view of the moon at 98x is stunning (and I can easily go up from there). Clear skies to you.

depends.........if.....I have time to plan ahead, and I know its going ot be clear all night, Ill always set up my 8 inch SCT "Wilma" so she has time to cool down.Razor sharp details etc. But.....if its a spur of the moment observing time, I will grab the C102HD , also razor sharp images but cool down time is almost non existant.And at f/10 it also has little color.

I use the 102mm refractor for lunar sight-seeing when time and/or energy is short, but the lure of moonlight is irresistable. I use the Newt for planned sessions when I want to study particular features or regions in as much detail as conditions will permit.

My 6 inch Dob. It's my first and only scope. When viewing DSO, I often think that my scope is a bit small in aperture for the job. But when I point that thing to Moon...Oh man that thing gets the job done, and very well btw!

For sharp synoptic views of the Moon my 125mm refractor is my scope of choice. For the close in vistas, my 12" SCT does the trick.

My two favorites would be my C8 with the binoviewer when the seeing allows and there is time to let the scope cool down and then my C102F which gets used the most because of time constraints and seeing here in New England. A problem comes up when I have decent seeing and I want to do video imaging using the C8.
These days I am more interested in the visual side of things and can't wait for these clouds to go away.

NP-127 with Denk II's seem to show as much detail as I can see in any scope under all normal seeing conditions. For those once-a-year excellent seeing conditions, I will see more in my 15" Dob, but it's a rare night when that happens!

For lunar viewing it would be my 5 inch (127 mm, F9.3) Meade ED refractor. This is because the seeing at my site is usually not very good and the refractor suffers less from seeing conditions than my other scopes. It is also pretty lite and easy to setup. The view is crisp with little or no chromatism and the scope can stand more magnification than my catadioptric scopes (per inch of aperture). Contrast is also good.
On the other hand, when I'm imaging the moon (which is most of the time) I prefer my Mewlon 250. Its longer focal length, greater light gathering power and greater potential resolution are assets for imaging.

Well, the "Aperture rules" idea doesn't count for the Moon as it's bright and "close by" so a smaller refractor would be fine as well

I don't agree completely... aperture is still linked to resolution. Although the moon is bright, it isn't necessarily very bright at high power, particualrly if narrow band or even broadband filters are in use. Small apertures are OK for general low or medium power views especially in poor seeing conditions, but there is surely a benefit to larger apertures when we move to higher magnification and want to see very fine surface detail when the seeing conditions are very good. On such nights there is no comparison at all between what, for example, my 5 inch F10 SCT shows when compared to my 10 inch F12 Mewlon. Maybe however it can still be argued that a high quality 5 inch refractor is adequate at least for visual observation on most nights... but I wouldn't think of a 3 or 4 inch instrument as being quite optimal for study of really fine surface detail like the rille in the Alpine Valley...

I think that for visual work a 5 inch refractor is fine and also does a pretty good job with astrophotography on most nights... but that being said I think a 6 inch would be better and is maybe the best compromise in the refractor range. The usually cited problem is that refractors give better contrast than centrally obstructed scopes but I think this really applies only to visual observation rather than to imaging. Refractors probably also hold collimation better. But, reflectors, whether SCTs or Newtonians or Dall Kirkhams etc. usually give you more aperture for the money and any of these is fine. If your seeing is only average most of the time then I don't think there is much sense exceeding a 10 or 12 inch reflector. If you have plenty of really good seeing then scopes up to 18 inches or so would be a big advantage if you want to capture really fine detail in an image, but at least in my case I doubt that seeing conditions would support such a large scope. And I sort of have the suspicion that (other things being equal) the closer to the equator you live, the higher in the sky the moon usually is and therefore the less atmosphere you are looking through. So, my instinct is that the closer to the equator you observe the more likley you are to benefit from a larger scope (but I've got to admit that I've never seen this thought mentioned in any discussions of this topic and maybe I am wrong here...)

I know an 80 mm scope can give very good views... I used nothing but a 60 mm scope on the moon for at least five years. I'm just referring to sort of ultimate views of very subtle features requiring more aperture...

8-inch F-10 Newtonian Reflector; A "Dynamax 8 Deluxe" circa 1958. Great for colorimetric work and the focal ratio makes for some good close views of features.
I am currently in the preliminary stages of restoring an old 6-inch F-10 Refractor. but this may take a while.

Extra aperature and thus resolution can make a significant difference provided the seeing is good.
To illustrate, two two photos, both of Agatharchides P. Both are taken with the same camera, the first through an FLT132 refractor at 4625mm FL, the second through a Mewlon 250 at 5400mm FL.

I think everyones is going to answer more or less "the scope i have". That said, and it seems thta what you might have wanted to ask was - if you could own any scope for lunar - what would it be within reason?
I would have to say a long focus 12 1/2" reflector. Barring that, a Celestron 14 or any classical cass system of similar aperture.

Why 10??? 12"!!! There are a couple of 12 inchers I covet but they are not available. The 12" hanging on the Lowell 24 or the 12" in storage at Lick. They would be THE ideal lunar scopes... for me.

I really liked the comment on aperture and resolution- its very much to the point. And the images help show. I wish they were on the same night... to keep seeing effects nearly the same and shadows, of course.
All of which has got me to thinking about using my same camera on the 6", 8" and 12.5" Newtonians to show the differences resolution makes. They all have homebuilt optics by me, so I know their quality well. I have found my 8 matches a 6" AP a neighbor has pretty well - seeing is usually the limiter. My 8 and 12 have about the same FL; the 6 I'll have to use a barlow with. I'll let you know when I get a chance to do the test, it should be fun - unfortunately skies have been bad here lately.

Hi, when I was offered a choice of telescope by my wife to celebrate our 25th wedding anniversary in 2005, after long consideration I plumped for the Orion Optics OMC200 mak cas telescope, it is F20 focal ratio. I have never regretted the choice as I wanted a dedicated lunar/planetary telescope. It gives enough aperture to pull in lots of detail, contrast is good and it is a surprisingly compact unit. Imaging is easy as I can often get decent images at prime focus without the use of Barlow lenses. Anyway, at the end of the day, the telescope you use the most is the best or your hobby. Keep well.

For planned sessions, my Equinox on Vixen GP, but for quicker looks from the garden, my 127 Mak on modified AZ3 does well too. The Equinox gives terrific views and really soaks up magnification, letting me get super-detailed views. The Mak can't take as much power, but it's a lighter, easier to set up kit and gives good contrast and brightness for a g'n'g setup.

... the most important requirement is that I be very relaxed while observing... when choosing a scope I like the one that is most comfortable to use... and that's that.
The table top 3.5 inch MCT is my favorite telescope for lunar observing... I love the Meade ETX 3.5 and the Questar... I use a Questar 3.5 with 16 mm eyepiece ( 80-130x)...

Astro-Physics 254mm f14.6 Mak-Cass on a 900 GTO mount. Minimum 1/10 wave (system), 23% central obstruction, coma-free, permanently collimated, sophisticated design with attention to thermal control results in typical cooldown times of 15-30 minutes, the mirror retains its figure while cooling, butter-smooth focuser with no image shift and no need for focuser lock for photography, and antireflection coatings you have to (not) see to believe. Although it was designed as an ultimate lunar/planetary scope, its superb contrast makes it an excellent, albeit narrow field, deep sky scope as well. Stick a Baader MkV and Zeiss Abbe orthos in it and it just screams on the planets and the moon.

My 5.5" Mak is good for both visual and photographic use on the Moon, and will when seeing permits allow 'silly' magnifications.
The Ranger is great for quick looks using an alt-az at up to about 70x, and when mounted securely on the LXD75 works really well with a 3-6 Nagler on the Moon.
I wouldn't swap either.

My thinking on this changed this spring. Up until a few months ago I was all about piling on the aperture and magnification. "Piling on the aperture" has limited meaning here, since my Big Gun is only a 6" Dob. But it has a good mirror and gets me in pretty close.
Then I read Leslie Peltier's Starlight Nights--which I would make everyone read if I could--and he changed my mind. I'll let the man speak for himself (p. 60):
Quote:
I feel quite sure that I first viewed the moon in my small scope with just as much incredible delight as Galileo did in his. It is true that I had seen photographs of the moon and therefore had some vague idea of what its appearance would be like, but I still was wholly unprepared for all the wonders which I found on that first night as I explored the lunar surface. No photograph has yet been made which is not cold and flat and dead when compared with the scenes that meet one's eyes when the moon is viewed through even a small telescope.
From an aesthetic sense, at least, it takes a small telescope and low powers to do full justice to the moon. While it is often possible to utilize the very highest powers of the scope to ferret out some small detail of cleft or craterlet, it is only when the entire moon fits comfortably within the field of view that she is at her dramatic best. Only when one sees some empty space about her does she seem to float suspended in the sky like the neighbor world she is. This is the way I always saw her in my 2-inch telescope.
Now, if the seeing is steady I am not above pulling out the Dob to go after the craterlets in Plato or Catena Davy, or to trace some rille or scarp I've never followed from one end to the other. But ever since I read that I have leavened my high-power viewing--which is usually a Feature Hunt, with its attendant preparation and rewards--with a lot of low-power viewing, which I spend just relaxing and taking it all in. Of course other observers may find that things work differently or even oppositely for them--perhaps "flying" over the surface at high power as a relaxing way to contemplate the moon.
I suppose part of it has to do with IYA2009. I've been thinking a lot about early stargazers from Galileo to Leslie Peltier and how much they accomplished with equipment which by today's standards was laughably modest. As one who suffers from occasional bouts of Aperture Fever and New Gear Sweats, it is nice to switch off every mental circuit connected to achievement, competition, and the acquisition of material goods, sit down in the driveway with my little Mak at its lowest practical power, and just spend a while gazing at the moon and letting the crazy seep out.
Clear, moonlit skies!

12.5" f/4.5 dob, got to love how it shows the wrinkle ridges on the Mare. If it's a quick look then the Tasco 3" f/15.75. Keeps everything grey. These are over the 7" f/15 Mak beast. I guess I just like to push the scope and twiddle knobs.

my 12" dob. Aside from burning my eyes out, it provides great lunar views, I've seen 8 craterlets in Plato with it. But if the moon is up, I don't bother lugging the 12 incher outside, its just too much work and the seeing is likely *BLEEP* anyway. Although for moon and planet-only viewing, I've got my 5" Mak reserved for that as it's easy to chuck out the door in one hand at a moments notice......only thing missing is the mount

I have a CPC 1100 and a recently purchased NP 101.
I was viewing the moon the other day with the 101 using a 10mm Ethos (also recently purchased) and then added a 2.5x Powermate.
The views were awsome. Clear and detailed. The moon filled the EP and was clearly visible using the Ethos alone.
Very impressive.
After reading the posts I can't wait to see how the Ethos performs in the 1100!

I haven't posted (or even lurked!) on the Lunar forum for a while... I need to get back here! In my 3-1/2 years in astronomy, I've learned- the two things that I enjoy viewing most are the sun- and the moon. There's more detail of interest on our two neighbors than anything else. My favorite scope for lunar use? A 4.25" Delmarva Schiefspiegler I built. Unobstructed optics= fantastic contrast; only mirrors= perfect color/no color correction issues; f/27= high power with simple eyepieces. Favorites= Orion Ultrascopics 20/15/10mm. A Vixen Polaris keeps it on target.
Unobstructed mirrored optics are really a fantastic way to observe the lunar surface. I'm surprised more people aren't exploring these scopes.

Gets my vote for the finest amateur scope ever made!
-drl
Quote:
Astro-Physics 254mm f14.6 Mak-Cass on a 900 GTO mount. Minimum 1/10 wave (system), 23% central obstruction, coma-free, permanently collimated, sophisticated design with attention to thermal control results in typical cooldown times of 15-30 minutes, the mirror retains its figure while cooling, butter-smooth focuser with no image shift and no need for focuser lock for photography, and antireflection coatings you have to (not) see to believe. Although it was designed as an ultimate lunar/planetary scope, its superb contrast makes it an excellent, albeit narrow field, deep sky scope as well. Stick a Baader MkV and Zeiss Abbe orthos in it and it just screams on the planets and the moon.

My 4.5" Newtonian with utterly perfect optics. It handles 100x per inch of aperture - the limit is in my ability to deal with a pinpoint exit pupil. I have never seen any optic as perfect - the diffraction pattern looks like the output of Aberrator. With this scope I just gaze for hours hither and thither, from the limb to the terminator to the midlands, and a vast tableau of details emerges no matter where it points. I can see the Alpine Valley rille - amazing performance for a 4.5". Last night I saw the tiny craters around the Apollo 11 landing site. Hypatia Rille looked like an expressway from an airplane. At f/8 collimation is a breeze. Eventually I will put the optics in a first class tube with a good focuser but the "Meade" name plate will follow it.
My 10" f/4.5 gives magnificent views but is plagued when the seeing is not perfect. So the 4.5" gets the nod, hits a home run every time up.

This is the scope I like to use for Lunar viewing. A Meade AR5. I changed out the focuser for a Crayford. Picture 1.

A picture of the focuser. I changed out the focusing tube with one I made by hand. The focuser works OK and was much cheaper then buying a new focuser.

My 10" Dob! I thought it was cool in my ST80.
On a lark decided to try the 10". WOW! 300x was crazy fun.

My favorite scope for lunar viewing is probably my 10" Newt Dob with a binoviewer and a #47 Violet filter. The views are very detailed at 300X. That is my preferred high magnification. If the seeing is excellent I may bump it up to about 400x, but that is my limit. Anything more than that and the floaters in my eyes are sheer torture, though the binoviewer and Violet filter help.
Someday I may take out my 8" Newt mounted on a CG5 with dual drives, also using a binoviewer and Violet filter. It would be great not to have to nudge the scope to follow the Moon. But a fairly big Newt on a GEM is not something I really want to drag out to the yard. A Dob is much, much easier.
I have to give honorable mention to my 90mm Mak. It's my favorite grab-n-go Lunar scope. However, my enjoyment peters out at about 150x with this scope. But a quick look at the Moon using lower mags can be very pleasant.
My C4-R is also a good lunar scope. Sadly, though, it hasn't seen much use for many moons. I should probably sell it.

Wait a minute! I keep forgetting about my 6" Mak. I really should try that out on the Moon! It would probably do a great job, not too heavy, easy to set up on a driven GEM. But that long cool-down period always makes me think twice about bringing the big Mak out. Maybe it's time I sold it as well as the 4" refractor?
