I am going to purchase one of these 3 to go with my 12.5 Morpheus and 24 ES 68 degree eyepiece. The primary scope is a 10" F/4.7 dob, but I also use a C6 F/5 newt and will be building a new 17.5" shortly. That will leave me with focal ratios of f/4.5, f/4.7, and f/5. 

 

I doubt there is a clear winner here, so how would you rank these? Which ever one I decide one will be the only one I add to my collection before the Golden State Star Party, and it will be the foundation I will build my eyepiece set on in the sub 10mm range. Note: I plan on adding a 17.5 Morph and a 30 ES 82 or APM 30 UFF later down the road. I do wear glasses and I do a lot of outreach. These eyepieces will be used often for both. Once I finish my 17.5" scope, I may add a few 100 degree eyepieces to complement this set.

 

If I chose the 6 Delos, I will most likely build a Delos set and go with 6, 8, 10 Delos. This leaves me lacking in the high power area for my max power would be 200x. I could aid this with my 1.8x barlow or a 4.5 Delos down the road. 

 

If I chose 6.5 Morpheus I will Most likely build a 4.5, 6.5, 9 Morpheus Set (although I may get the 5XW over the 4.5 Morph due to EOFB issues the 4.5 mm is known for)

 

If I chose the 7 XW, I will most likely build an XW set and have: 5, 7,10 XW.

Vixen 3.5mm LVW is a very viable high power for those focal ratios.

 

I can't offer you advice on the original question, as I don't do wide fields at those focal lengths. I do 5 and 7.5mm Tak LEs. - 50 deg.

 

good luck,

I have no problems with the XW pentax except the 14, and 20mm, I find them to be the pinnacle of wide field eyepieces. Since they are on sale, get them.

I found the 3.5, 5, & 8 LVWs better than XWs, but also like the XL 5.2 in preference to XW. 

 

Owning also all the Morpheus FLs, they have upstaged the others above, except my XL 5.2mm and LVW 3.5mm.

I did a direct comparison of the 6.5mm Morpheus and the 7mm XW this winter.  Both are excellent and it was very hard to pick a favorite.  For deep sky I leaned toward the Morpheus.  For the Moon I leaned toward the XW.   I've owned the 6mm, 8mm, 10mm, 12mm, and 17.3mm Delos.  If you like their presentation they might be a little sharper than both the XW and the Morpheus.  I just find the Morpheus more comfortable and engaging.

+1 for the 6.5mm Morpheus. I sold my 7mm XW as it was less comfortable.

 

I see from your signature you have no XWs, but have kept the 10mm Nikon SW!?

The 10mm Nikon is for lunar/planetary.  I think the Nikon's are the best lunar eyepieces I have used.  So I use the 10mm Nikon and the 10mm Nikon with the 1.6x Nikon barlow and the 3x TV barlow for all lunar observations.  I don't use it for deep sky.   For deep sky I use the Morpheus and DeLite.

 

So in the XW's are great eyepieces but I don't like them the best for anything.  For deep sky I like the Morpheus and DeLite more.  For lunar/planetary I like the Nikon more.

The 7 XW is excellent .they all are
My only caveat is a 6mm Delos is one of the only 6mm out there
No delite in 6mm
No morph in 6mm
No ES
No Nagler
BST ??
You see where there's gonna be a hole in the 3mm to 10mm range
6mm is ( to me) a critical FL
Maybe a Nagler zoom

Well there is the 6mm Nagler T6.

 

I agree that 6mm is a very important focal length in the eyepiece case. In my case it's the Ethos 6mm.

I forgot about the ethos & the Nag

I like the 62° to the 78°FOV range

The Ethos line is , for me is to much FOV

 I hate peeking around corners

The 82° Naglers are at the upper limit. 

I was looking at the 6mm pickings the other night.

 They seemed slim.

I have to say the 12.5, 9 and 6.5mm Morphi are all excellent eyepieces. If you like the 12.5, you will very much enjoy the 6.5 (and the 9).

Delos if possible. smirk.gif  It might go deeper with a big 17.5" scope also. Otherwise 7mm Pentax or the Morpheus. The 6.5 Morpheus is one of the better ones also, can't go wrong with either really, choose the design you think you'll enjoy looking through with more.

 

Having owned the same scope as you, and having started with a 5mm Pentax XW, I'd definitely want a 6 or 7mm more than a 5. But I see your small dilemna now. Also, I see you live in Nevada, therefore get whichever you please, probably can make some regular use even with the 4.5. 

 

The Pentax's on sale atm are really hard to pass up as well.

I'm leaning towards the 6.5 Morpheus. If I get the 6.5, I'll be set with 6.5, 12.5, and 24 mm for this star party. I'll then focus on adding the 9mm.

With my 1.8x TV Barlow, ill have the ability to go 5mm Morpheus and 3.6 mm morpheus (for the C6 Newt at 200x).If I decide I don't like using the Barlow I can add a 5XW or 4.5 Delos in the future. Plus, once I eventually add the 17.5 Morpheus I will once again have a nice set of my favorite 4 Morpheus in 6.5, 9, 12.5, and 17.5.

There is no 6mm T6, just 5 and 7.

 

Ethos and Delos are available in 6mm. The discontinued Radian was also available in 6mm.

 

I’ve been contemplating another high power EP to supplement my 8mm Delos. I used to have a 6mm Delos but I wasn’t in love with it. The 6.5 Morpheus seems like it may be a better value. On the other, I could just have a 12T4 + Barlow “baseball bat” setup.

 

The 3-6 Nagler Zoom is worth considering if you can live with the reduced AFOV and short eye relief.

FYI....there was a test done on the 8mm range a few years ago against all these high quality ep's and the Vixen 8mm LVW won out. I had a 17mm once, very nice and comfortable EP. Probably should have kept it?

I did not think the LVW's provided a particularly engaging or "lively" field - except for the 22mm.  Probably coating technology has advanced quite a bit beyond what they had.  My favorite LVW was the 22mm.   I had one that was essentially perfect and I decided to sell it for some stupid reason.  When I picked up another at some other point in time it was not as good as my first 22mm LVW.  I've learned over the years that if you get a sample of an eyepiece that seems to be exceptional - don't sell it because there is no guarantee that the next sample you pick up will be as good.

If $ becomes an issue the HD 60 6.5mm is VERY good (60*) Same with the ES 6.5mm (52*)

I have the 6/8/10 Delos but for your intended purposes, I will recommend the XW 5/7/10 trio. Having 240x on tap with the 5mm before you have to start barlowing is desirable and for outreach, the XWs twist eyecups will fare better than the more-involved affair with setting the Delos eyecup. Plus, XWs are so comfortable and easy to use, another big plus for outreach. They'll never know how good they have it!

In some other thread I read somewhere someone measured the morph @ 6.7mm instead of the stated 6.5mm. I have this ep and love it, have no compaints, but have no comparison.

Probably the same thing I was thinking when the 8 Delos was a little too low and the 6 Delos was a little too high in magnification...

(I wasn't aware of the 7 XW at the time)

I recently picked up a 17.5 Morpheus on the classifieds. Comparing all 3 series, they all share similar characteristics. Eye lens & eye relief are about the same. Field of view is the same ballpark. You can't really tell a difference in the XW vs Delos, but it's noticeable that the Morpheus FOV is larger, but not that much. I think it all boils down to personal preference with the cosmetics. If you prefer to use the eye cup up, the XW would fit your bill. Eye cup down, Morpheus or Delos would suit you. Morpheus & XW have rubber grip, and Delos is mostly aluminum. The Morpheus can be used in 2" focusers, but the XW & Delos would need an adapter. It's been my experience that eyepiece focal lengths = f/ratio of telescope produce the best views [depending on seeing conditions].

Morph in 6.5mm!

Yep, love my Morphies.  And they just happen to be a little lower cost than the others we are discussing here which makes them even better.  It’s rare that you get the same or even more for less in this hobby but in this case you certainly do.  Props to Baader for coming up with these gems!
