After a multi year period with no changes in my eyepiece lineup, I'm thinking of moving to a dedicated binoscope eyepiece case. This gives me space to grow the set. At the moment I have the 24 Pans and 12.5 Docters, plus some Zeiss 2x barlows that give me 6.25 Docters. I'm thinking of discarding the barlows and going native for higher power. I'm looking at 4 or 5 pairs for a complete set in the APM120's and 82's. 

 

I want something in between the pair I have, and am thinking 19 Pans. On the higher power side I'm considering something like the 8 and 6 Delos pair. I used my friends 8 Delos with mine and was surprised how comfortable it was, but shelved the idea at the time of getting the pair. I've tried the Delite pairs, and am not convinced about the smaller FOV, and it seems to me the top of the Delos is a better shape for bino viewing than the Delite.

 

The Docter is going no where, but what do you think I should get to build around it?

An important question is your IPD.

Mine is 61.5mm.

 

Definitely agree on the Doctor 12.5mm - amazing comfort, transmission, etc.

 

I had pairs of Delos for binoviewer/binoscope viewing.

Definitely comfortable.

However, tight in IPD for my facial structure.

Sold off one set.

 

Another option is the Pentax XW in 10mm and 7mm focal lengths.

They can be decloked to reduce their footprint.

 

I thoroughly enjoy my Baader Morpheus 17.5mm, 12.5mm, 9mm and 6.5mm pairs.

The 12.5mm, 9mm and 6.5mm are parfocal. 

I would purchase a pair of the 17.5mm (definitely optically better than the 19mm Panoptics - larger TFOV and better eye relief).

Also purchase the Morpheus 9mm and 6.5mm in pairs.

 

I also own the new APM 12.5mm UWA 84° eyepiece in a pair - very close optically to the Doctor 12.5mm.

APM is releasing a 18.75mm UWA 84° version later this year. 

Something to decide - buy Morpheus 17.5mm now or wait for the new APM 18.75mm release.

 

Lots of great choices !

To many great choices. Makes the decision harder.

 

My IPD is around 65mm, so in the past I have found the Delos acceptable. I don't know why I was considering the 19 Pan, except it sits well with the 24 Pan. The 17.3 Delos is an option. Have never looked through a Morpheus. I'm not sure why I would choose it over a Delos.

The 9mm Morpheus and 12,5mm Docter have very simular ergonomics so I would give a +1 vote for the Morphs.

The Baader Morpheus is extremely comfortable. I find it easier than Delos.

Eye relief  - draw.

Light transmission - draw

Morpheus is lighter in weight - advantage to Morpheus.

TFOV - Delos 72°/Morpheus 76° - advantage Morpheus (definitely seems larger than the extra 4°)

Cost - Morpheus is $110 US less expensive - definitely advantage to Morpheus.

Here is my binoviewing (binoviewer and binoscope) pairs in 2010.  I haven't changed much since except adding a few pairs of 2" eyepiece.

So no starting over for me :)

 

Takahashi LE 30 and Zeiss/TMB 25 are most used pairs with binoviewer.

Docter UWA 12.5, Nikon NAV SW 17.5, Kowa 21, and APM UFF 30 are most used pairs with binoscope.

The APM 18UFF eyepieces are wonderfully comfortable and super sharp. Didn't you get a set with your 120s?

Lots of people praising the Morpheus. Why did you find it easier than the Delos? Are they a slimmer barrel?

I asked Markus to include an L-Bracket for mounting the binos to my Discmounts instead of the eyepieces. So no I didn’t get the 18UFF.

After all the positive comments about the Morpheus, I bought one to have a look for myself. What I was most interested to check was the barrel width compared to the Delos. I can bino the Delos okay, but a smaller barrel would be a bonus. I can see now that the Morpheus is noticeably thinner in the barrel than the Delos, and it's quite close in dimension to the Docter which I find very nice to use in the bino. The Delos barrel tapers outward from the top and reduces the clearance with its bino pair, where as the Morpheus like the Docter goes straight down to leave a larger gap from its bino pair. It's quite a deal smaller and lighter than the Delos as well, so all round I can see why it has become such a popular bino eyepiece.

 

That gives me the confidence to go and buy some more now and make up some bino pairs.

I read somewhere about fitting a ring under the eye guard to effectively raise it to counter the long eye relief of the Morpheus. I have noticed already it is very easy to get blackouts when getting too close to the eyepiece, and I would prefer to be able to rest against the eye guard when observing without the black outs. Anyone have any info about that?

Yes, doing that works on my 9mm. You can purchase these rings directly from Baader. The newer versions actually come with them now.

Thanks Matt. I bought this one used, so no ring. Is the ring the only difference between the older and newer eyepiece?

Can someone who has the eyepiece confirm the diameter of the unfolded rubber eye guard? The technical sheet shows lots of information but not that specifically. Based on the body diameter of 55mm it looks to be 46mm. I'm trying to see if I would be able to see both field stops in a binocular telescope. I know I can't quite manage at 49mm diameter and 15mm eye relief. Thanks for any help.

 

Take care,

Brent

You are correct, the eye guard of the Morpheus I have is 46mm in diameter. The eyepiece cap has 46.5 stamped on the inside of it as well.

Allan,

 

Thank you. I'll turn my "eye guard simulators" down from 49 to 46mm and see if I could see both field stops at 20mm eye relief. I hope so, these seem like a great option if my particular physiology will accommodate them.

 

Take care,

Brent

Bill, do you find you use the 17.5 Morph or 18 UFF more, or rather, which do you like more?

I use the 17.5mm for astro viewing in both the 70s and 100s and the 18mm in the 70s for terrestrial; just seems to suit my eyes better with a smaller fov for daytime viewing (pupil dilation...:question:)

Ok, I like the sound of that. The 17.5 are on my list to cover the gap between my 24mm and 12.5mm eyepieces.

The newer versions also come with the screw-on eyeguard. No more eye guard coming off when unfolding them. IMO, using the extender and screw-on eye guard transformed a good eye piece into a remarkable eye piece. I also like resting my eyes against the rubber, no more blackouts and they just “fit”.

Best, Karl

I agree with most everything said about the Morpheus 17.5, as well as the rest of the line.

 

One thing I don't like about the 17.5 specifically, is that in my 100mm Lunt bino, it shows a lot of ghost images of out-of-the-fov bright stars, especially when panning or sweeping.  These ghosts tend to be quite bright and moving at odd angles, which is distracting.  I haven't tried the APM 18, but it may be better since it has a smaller FOV.  I doubt if the 17.5 is any worse for ghost images than any other eyepiece of this F.L. and FOV.

 

A plus for the Morpheus that I don't recall being mentioned here is the straight tubes.  These are much more stable in the focuser collets than others with the safety cut-outs such as the TV and ES brands.

 

I also like the sound of the screw-on eye guards.  Mine are all the kind that slip on the threaded extenders, supplied for free by Baader after purchase, and will come off with rough handling or folding/unfolding.  The extender threads going into the eyepiece tops are also a bit loose.

 

None of these problems cause me to consider parting with my Morpheus eyepieces, however.

 

Rick

Ghosting images are a function of eyepiece fieldstop diameter.....the bigger the more off axis issues...
