Nice and now even nicer
It's often said that the Ethos range falls into 2 "sets" depending on the scope thats being used:
21-13-8
and
17-10-6
The 4.7 and 3.7 seem to be considered as "standalone" items.
Never being one for "rules" I seem to have a crossover set with some from each group but only the 21-13-8 group complete.
John,
That's why I have both sets, I'm still teetering on the edge over the 4.7mm and I do have enough spare cash in the UK bank, dangerous times. I feel the thing that is stopping me is 1 month of poor weather, dare I risk it.

So sorry to hear the problems you have had, the cover just highlights it all, corners cut. It is so sad as mine was only a little more expensive and is clearly in a different league to what you describe. Hope you can fix the issues and make it better.

The 10mm Delos was my first and I agree sharp as a needle and contrasty, pretty flat field too. I spent ages comparing it with the 10mm Ethos and in the end gave up. The only reason I kept the Ethos was that I have not long since bought a large Dobsonian, tracking is somewhat easier. Great eyepieces, I still have the 4.5mm as I don't have a 4.7mm E (yet).

I don't have a Paracorr but as far as I know you can use it the same way. Insert an eyepiece and use the tuneable top until it's the correct setting. Assuming it's in focus, you don't need to touch the scope's focuser anymore. Whenever you insert another eyepiece you just have to use the tuneable top until the new eyepiece is in focus. That's the correct setting for it. This way you won't need a red light to see the A, B, etc, marks, and won't need to remember the settings for each eyepiece either.
I see on your signature that you have TV eyepieces. Your 26mm Nagler needs setting "F" according to Tele Vue website. If that's the first eyepiece you're going to use that's all you need to know. Turn the tuneable top to F setting, focus, and when you're going to use a different eyepiece you just need to move the tuneable top until this new eyepiece is in focus as well. This is especially useful for non-TV eyepieces as there is no table with optimum settings anywhere for other brands.
Learn something every day, it's logical when you think about it but why didn't I see it, Many Thanks!

I have owned a Type 1 TV Paracorr and currently use a Type 2 on my 12" Dob. The biggest difference I would highlight is that the Type 1 only has 1 off screw to lock the tuneable top. I found that this introduced an element of slop in the tuneable top if using a heavy EP. The Type 2 has 2 off locking screws on almost opposing sides. This locks the tuneable top more securely and eliminates the slop.
Totally agree Ian, it is much better made altogether but for 400 quid it needs to be. I personally thought the edge sharpness was a bit better too having had the two together.

Steve I wrote a review on both last year, it is in Members equipment somewhere, about 6 months or back.

I won't be selling the 31mm in a hurry. I am hoping for some nice clear skies at SGL XI to let me 16" Dob do its stuff and he 31mm would definitely be part of that test. The 27mm and 35mm Pans are definitely next on my wish list, probably in that order as I have a big jump from the E21 to the N31. I bought a P24mm a few months ago for my Lunt 50Ha and didn't get on with it so passed it on to Shane. I might ask to give that a go in my Dob to see whether or not I need to look out for another one.
Derek,
As much as I agree with with Shane about the 24mm I sort of know what you mean about the 24mm and I think it is not big enough. For the Dob and the SC I like big eyepieces, I like to get my hands on them, like the 21mm E and 31mm N. I use the 24mm in the topscope on the SC and rarely move it anywhere else, though I have been trying it of late with the elusive Horse. I don't really find the jump from 21mm to 31mm is too much, then of course like you I have the 41mm for those wider fields in the SC.
I do though find the 35mm, for some reason I can't nail down, preferred weapon in the M/N 190mm and the widefield in the 180mm Mak. I always wanted a 27mm and was on the verge of getting one when I tried you one week diet where my eyepiece cases lost weight and bank account gained it. The other thing with the 27mm Pan it gives about the biggest field in the SC when used with the .63 reducer, though it has been a while since I played games with it. I was going to use the 26mm Nagler for this but it vignettes badly, something the 24mm Meade UWA does not, wish I never parted with that one in the SC it was almost as good as a TeleVue. I know Shane loves his 26mm N, this was the one in the TV's I couldn't get on with, I guess we are all different.

Personally I would not get rid of the 31mm, it is a really good eyepiece and I have the 35mm Panoptic as well. To me it boils down to the scopes you have, the 31mm goes in the Sumerian, prior to owning this it hardly got used in favour of the Panoptic which still gets used in my other scopes.
I know what you mean about sets though, 4.7mm is calling me again though I can't hear the 3.7mm yet.

The question is Derek, where do you go now, full house. Lovely set of eyepieces which sadly not everyone can afford but for those that can they really lift the pleasure of the hobby, though of course some do not get on with them, fortunately I do.

Mark,
I don't know if you ever read any of my comments about Ethos and Delos but I used to have all the Delos range and most of the Ethos range, only the two shortest ones missing. I got tired of trying to find differences between them so sold most of the Delos, the Ethos being better in my Dobsonian scope from a nudge point of view. I really couldn't see anything better, deeper, clearer or less scatter. Which ever you have it is very difficult to better them, maybe you need to be in Namibia or somewhere like that.

John,
Congratualtions, I am now the colour of the eyepieces, green and I have a black top on.
Nice one you talked me out of buying one two or three times, we have both been hovering over the buy button for a long time. Well when the free clouds have gone and you get a clear night or two aroundabout May will you do the site review? I will then start all over again wanting one.

Here is my latest update with the addition of an E4.7mm...
The E3.7mm space left at the bottom is purely coincidental
I bet your nose has grown Derek. Coincidental, a likely story.

I had the 14XW a few years back and it was as John states, I did prefer the Delos 14mm being a TeleVueaholic.

Michael,
I personally think you could do a lot worse than the 14mm Delos in view of you having to wear glasses. The old Meade 5K 14mm would be nice but that again would be tight for you with the ER.
Alan

Looks like a nice spread there Shane, I don't find TeleVues 10mm relief in the 15mm Plossl and Nagler 3-6mm zoom any problem and I don't believe you where glasses.

I bought this 16" Flextube a few weeks ago and have now added a MoonLite CR-2 focuser and some nice sturdy carrying handles which really help when setting up and moving it around...
Now all need is a clear night
Sort of explains why the weather is so bad over there, I have the same focuser but the black one, dark forces Derek.
Nice scope!

I said at 100 that this was a bit like an innings of the great G Boycott, now at 125 it is building at the same speed, though this cannot be out.
I have seen some lovely eyepiece cases on this thread filled with some lovely eyepieces, it is sort of nice to look back and remind ourselves what we had a few years back.

Michael,
It is not quite there as the Panzerfaust does not come in a 82 degree size, the Panzerfaust Klein must be the designer version by Calvin.

Kerry,
Same cases i use they are very good and much cheaper than Peli. Nice selection you have there too!

Great reports both of them. I am very pleased with my 18 inch from John and a little like you I sort of wish I had gone for a 20 inch which I could of at the time. I was a little worried about weight as I was getting older. Now of course it puts both of us in the 24 inch mirror next step bracket
:eek: .The only down side is I don't seem to use my other scopes any more.

John,
It is all about power really, the XW5 is a very good eyepiece, as good as anything on the market, maybe a tad better than Delos though there is no exact match apart from 10mm and up, I'm still not sure on that my opinion seems to change from night to night.
My APO is 805mm F/L so it gives me X160 as near as makes no difference. a bit on the low side, the 4.5mmD gives me X178, ideal for Jupiter. On the 190mm my 6mm will give me X166 so sort of does the job there. I have not used the 5mm for a long time and that a shame.
Ok it could be said that 5mm would give a nice round X200 on the one scope but with the much larger apperture and my good seeing X222 (4.5mm D) and up to X250 (4mm Radian) is no reall problem.
Apart from that its down to, I want to know what 110 degree field is like.
-
While I have power, it's been off twice already as the rain hammers down.
Yes I am very close to convincing myself I need a 4.7mm E. The spare Paracorr, it's a nice piece of kit but don't read my review or you may want your money back.
The daft thing is the case on the left only arrived a week before I went on the Derek slim fast diet, I don't know what to put in them now.
Alan
Show me your eyepiece/accessories case, please.

Congratulations on the 21mm Ethos. The only other good thing I see here is no space for another, it didn't work for me though I made the mistake of having a larger case.
