...must ... resist ...no need for more eyepieces ... no more for the binoviewer ... but the views are SO nice!!!!

OK I am going to follow your lead and order a pair ... :lol: (for real)

The nice thing with eyepieces is that there is a ready market for high quality slightly used....I just sold off my 18.2mm DeLites and LOA 3D Denks, so I'm "reinvesting" in something new.

Bill, I'm interested in these also and may end up with a pair before the sale ends.....

I want/request a direct comparo with the 19P's as the Morph offer more magnification as well as FOV!

Mike.....will do with the 19mm Pans.

 

Don't use the 19 Pans much anymore as I think they have been eclipsed by others.....my Pans are around 12 years old and I think coatings and optical design have made progress since.

High Point must be selling a slew of these while on sale.  My 17.5's are on the way too, plus a pair of 6.5's.  (Funded by a pair of Baader 8-24's + barlows).

Always find buying a new toy helps me with the winter after holiday SAD; February is always brutal.

 

The sun angle is definitely getting higher and Scorpius is rising in the predawn.

 

The summer Milky Way  will soon be here.

Here they are where they belong... arrived today after a prior cancellation of my initial order I re-order after I sold some eyepieces...

Tonight its cloudy, I can only compare the 17.5 with my 22mm (65 degree) LVW on terrestrial objects, but the reveal is surprising,... 

 

In home the 17.5 has a much better anti reflection coating then the LVW, internal blackening is a step better and really very good, but the anti reflection coating of the 17.5 is certainly not of the level of my 12mm Delos despite having "Phantom Group Coating", its really very dark inside the Delos...(and its full of stars...)

 

I did only a sharpness check on a streetlight illuminated side of a brick wall 100 yards away and here is my first surprise; the LVW is sharper toward the edge.

In the centre both are tack-sharp, moving the side of the wall to the edge of the field softness appears faster in the Morpheus then in the LVW...both units both barrels...

And then there surprise number two; If I move a detail of the wall to the 2 o'clock edge position of the field the view is much sharper then in the opposite - 8 o'clock position- of the field, all eyepieces, both barrels... and here also the LVW beats the Morpheus in edge sharpness, on the 8 o' clock position, the 17.5 is really soft, where the LVW is soft.

 

Eyerelief is plenty with my glasses I must use the extension ring as shown is the photo.

Well, I bought and sent back the 14mm Morpheus.....If these don't work out for me, back they go.

 

I will be directly comparing to the APM 18mm UFFs.

 

Only out return shipping.

You may have a good point there......time will tell.

 

Didn't I say in another thread that I wasn't going to be a Beta tester anymore....lol.gif

 

I'm willing to cut a little slack in trading more apparent fov for some softness at the very edge of the field.

 

Contrast is at the top of the list for edge detection of faint extended bright/dark nebulae.

It will be interesting to hear your impressions, Mr.Bill.

I was waiting patiently for you to finally test these babies wink.gif

Hope they fulfill your/our expectations...

 

Btw; APM is announcing the appearance of their new 18.75mm 90° EP in/around April. https://www.cloudyni...epieces-coming/

It will be interesting to compare this two, side by side.

I like your report, Garret.

So, what is your final verdict?

Is that edge softness bothersome...or you can "live with it"/are willing to "cut a little slack" in that regard, as Mr.bill so eloquently put it?

 

Btw; can you post some pictures of that wight-balancing system incorporated with the fluid head, that you have made yourself?

I have seen one photo that you have posted way back...and have a pretty good idea how to replicate it but will appreciate if you can attach some photos of the system without your binocular.

It is a quite clever solution.

In that way, one can loosen the drag & counterbalance of the head, gain more fluidity of the motion and keep the perfect balance of the system.

Am I correct?

 

Regards

Rex

FWIW, I have the experience where my Pentax XW20's are sharp to the edge in my 12" f/5 dob in a binoviewer (with no OCS!), but are not so sharp in my APM f/5.5 100mm APO binos.

 

Why? I don't know, but I have verified this several times. It is not my imagination.  tongue2.gif

The field curvature from a parabola mirror is in a constant relation to the focal length. With refractors this is unfortunately not the case. An f5.5 refactor can have the same field curvature of an f3 or f10 Newton depending on where the focus of the design was put. Since the ED doublets we are talking about here where specifically designed for binocular use, not photography as most refractors are, field curvature was most likely sacrificed in the design to accommodate better correction of other aberrations such as on axis CA which, with this design, is very well corrected, especially considering the focal ratio.

 

As always, the design of refracting optics is a compromise.

On my day-light binovcombo http://www.pt-ducks....#CR-binoviewing the XW20 result also on flat-field - the Pano 24 no... As these Morpheus have almost similar TFOV, I'm interested on knowing the experience of those like you, that have combos resulting flat field of view with the XW20 and these Morph 17,5 also worked well...

We have plenty of snow here, especially up high.  Some occasional rain through the summer would help us more.  Our snow right here at home is getting thin, but another system is supposed to show up Wed. night and Thurs., just in time for my new eyepieces to get here.  NOAA says it may not amount to much, so here's hoping. 

 

I also have a pair of the Morpheus 17.5's + 6.5's, arriving Thursday from High Point.  Must be traveling parallel to yours! choo-choo.gif

Just got mine....reach focus with plenty of backfocus to spare in my APM 100mm APOs....first blush eye placement comfortable using installed eyecups (that's HUGE for me when viewing for hours)

 

Fit and finish first rate and coatings appear well applied and minimal reflections using led flashlight to examine.

 

Daytime terrestrial view looks promising...afov huge compared to the APM 18mm UFF....real fov 2.42 vs 2.12 degrees.

 

No noticeable eye blackout noted during daytime.

 

Pincushioning present but well controlled.....less than 24 Pans.

 

Will evaluate using town lights 6 miles below me to the north this evening; that will reveal a lot about FC and astigmatism.

 

Astronomy definitely will have to wait with local weather conditions.

Sounds great, Mr Bill!

 

Just what I was hoping for to fill that gap in my eyepiece pairs.   According to tracking mine should arrive tomorrow.

 

I'm in the same boat as you, concerning weather.  Maybe I'll draw your clouds up this way since mine arrive later.

Nighttime test viewing town lights, business signs, etc showed a crisp, flat field in all quadrants to the fieldstop, using APM 100mm APOs.

 

Contrast appears very good with objects in shadows clearly seen and lighting appears sharp....can clearly read neon signs that were a challenge with other eyepieces.

 

Apparent fov suits my eye perfectly; can see fieldstop on outer edges of vision looking straight on axis but is immersive....

 

Lateral color very slight using my metal roof test....no noticeable color on axis.

 

Will have to wait for good night skies to further evaluate, but I'm extremely pleased with what I see so far.

 

These are light years better than the 14 Morphs that I returned; Baader got these right, IMO.

 

These will probably stay in the 100 APOs most of the time; seems like they are a perfect match for the binocular at the magnification I use most frequently for Milky Way sweeping.
