I've been considering getting one, but now I'm thinking it might not be worth it to me to get the 6 mm Delos.  I already have a 7mm Delite and a Pentax 5mm XW.  How can I justify it?

Life is short. He who dies with Delite, Delos, and XW wins!

 

Also if you have a relatively long focal length scope, the 6 would fill a gap.

At these shorter FL, in my opinion, it's totally justified to own 7mm, 6mm and 5mm for the moon and the planets, to always be able to get the sharpest highest power possible. I use the 6mm Delos on the moon and it's a very strong contender... I would buy it a second time because of it's overall quality, I am highly satisfied with mine on my 200x1000 newtonian, for the moon especially.

That's a tough one. I once owned a 6mm Delos, gave the best view of the Whirlpool Galaxy I've ever seen.

But I ended up exchanging it for a 3.5mm Delos, since it just couldn't compare to the star walking feeling my 5.5mm 100 degree gave me...

I don't regret it, the 3.5mm is the greatest thing to ever happen to planetary nebulas and Ice Giant Moons! Wouldn't have seen Triton without it.

Well, in eyepieces you CAN have it all if it's worth it to you.

Delos 6mm is perhaps my favourite eyepiece.............. it gives me 310x in my 18"F3.5 and 200x in my 6"F7.9

I went with a 6mm Ethos instead of Delos. Even though I have 5mm and 7mm Naglers. Life is short, if you can afford it, go for it!lol.gif

I have both the 7mm DeLite and the 6mm Delos which gets more use, mostly due to the larger FOV.

It all depends on the scope and what you enjoy viewing.  I love my 6mm Delos - I love all of my Delos!  I also love my full set of Pentax XW.

 

If the need arises, I can go 8, 7, 6, 5, 4.5, 3.5, 4, and 3mm (if I use the 8 and 6mm Delos with a Zeiss Barlow).  The Delos eyepieces handle a Barlow very well and sometimes the conditions let me play around like this.  Planet season will be here soon, so it's better to be ready! cool.gif 

 

Cheers,

 

Ron

Mainly for a 6 inch f/8 eq mounted apo in an Exploradome.

 

I already have a TMB planetary 6mm, a Vixen LV 6mm and a Baader 6mm ortho.

How are your finances? I have always argued for going in smaller and smaller increments when moving down from 10mm. I go from a 10mm Radian, 8 Delos and Ethos, 6 Delos and Ethos, and 4.5/4/7 Delos and Ethos. You may find the 6mm Delos the Goldilocks eyepiece--just right. I also have a 5XO that I rarely use because the eye relief is too small, and the field of view is only about 50 degrees of AFOV. If you end up with a 7, 6, and 5 you could always sell one of them based on personal preference.

I'm probably going to be the only one to tell you that, but I don't see the point of having a 6mm Delos, considering all the eyepieces you already have.
except for your own pleasure.

Mmmmm....what is the point of having any scopes or eyepieces at all other than personal pleasure? A hobby is a personal pleasure pursuit, is it not?

what I mean here is .the pleasure of having the Delos 6mm, without necessarily having a need for it, neither more nor less

Yes...I DO understand your point. But there is no need for any of us to have any astronomy gear. It’s a choice and a hobby...not a need. Therefore, buy what you want and who cares what others think? I know a gent who has about 7 grand tied up in his Astrophysics scope and mount which he uses about 10 times a year. But I’m not gonna tell him he doesn’t need it and he’d rightly tell me to mind my own business if I did.  It’s his choice. Just because I wouldn’t do it is no reason to think someone else might not.

so I give my opinion to the question, whether or not you agree with my opinion, does not change the fact that I answer what I think is fair and obvious.

Ok...understood. IMO, his justification is if whether he wants it or not. That’s really all that matters and the only answer there is.

Once I get the eye placement correct, it has stunning views.

Just remember he/she who have the most toys when they die wins.

I like the Delites, but like the Delos more. The 6 Delos is a real workhorse eyepiece in my scopes. I would get the 6, and then you may find you don’t need the 7 Delite.

You are probably correct.  I wonder, if, in practice, it will give much better views in the center of the field than the ones I have?  I have a precisely driven mount, a G11S.  The best of the three 6mm I have overall is the TMB Planetary, that our sponsor used to sell.  It seems to be as sharp as the Delite at f/8, over its entire 58 degree apparent field.

probably for the others yes, except maybe the Delite.
Delos and Delite are like brothers, I was told that they were the same, more or less.
so I think the center of the field must be the same.
my english is limited when i have to express my thought.
I think in my language but its not always written so easily.

Well that clears the matter up quite a bit. That's pretty much what i thought we're talking about here. Yes, you need a 6 Delos and probably a 6mm TAO too. They're both really, really great and you are very well placed to appreciate them.

If you have a scope with a large focal length, each mm difference might be very visible.  A 2000mm scope going from 5-6mm is 400x-333x, your 7mm would be 285x, so you'd definitely see the transition.
