What does "MOP" stand for? Can't have the same meaning as on the old Meade Research Grades? :gotpopcorn:

MOdified Plossl, according to Barry at KK.

That's very good to know, especially that it comes from a source.

From some old CN threads...

 

MOP

 

Made of Plastic

Mother of Pearl

Military Occupied Prefecture

Made to Order Production

Motor Operated Potentiometer

Make Owner Poor

Masuyama Optical Products

Meade Optical Products

Mysterious Optics Producer

 

Unfortunately the old Meade Abbe RG Orthos also had "Japan MOP" inscribed on them so doubt it means MOdified Plossl for them.  The way it is engraved on these new eyepieces as part of the product info though could very well mean what Barry stated.  But not in the case of the old Meade RG eyepieces as that was a country of origin stamp "Japan MOP".

 

Here a thread jabbering about possibilities - http://www.cloudynig...0mm-wide-angle/

You can find a 55 ish plossl for way cheaper

i ran into a a 56mm meade plossl smoothie Japan 5 elements

that does the trick for me

 And it's a pseudo-Masuyama...

Tony He picked up the UO 55 Plossl for $50 (off of me sveral years ago).  Finding a Meade 56mm smoothis for that price is unheard of!

I bought that off of you...?   That's great.  I've bought a few EP's off of Tony over the years.

Barry from KK has just sent an amendment. MOP actually stands for Modified Ortho Plossl. He had told the Factory to *NOT* include this on the finished products, as it was meaningless, unnecessary, and did nothing to enhance the appearance of the eyepieces.
This engraving will not be included in subsequent runs.
Those of you who bought the 60mm with this on it can keep a rare, error collectible, or can check with Barry about arranging for a replacement.

Was wondering the same thing. Would be nice if they brought the whole lineup back.

KK has confirmed that the Plan is to relaunch the Masuyama line, including some new focal lengths.
No details yet.

Modified Ortho Plossl ... an Efrle? :thinking:

The diagram provided by Masuyama shows a thin, biconvex element interposed between two symmetrical doublets.
Not exactly like an Erfle, but definitely similar.
Looks like they started with a true Plossl, and added a 5th element to flatten the field, thereby creating Ortho-like performance in a Plossl-like field.

That is great news IMO.  The current field of Plossls is exceedingly boring with form factors about as drab as can be.  The Masuyama form factor is quite unique comparatively and also nicely functional based on my experiences.  Will be nice to have them come back to market.

The initial run of 20 3" 80mm units has just sold out. I believe virtually all of them are within the domestic market in Japan, and then there is a single example in the Western Hemisphere.
The 2" 60mm first run has sold out even faster.
It looks like there may be 60mm and 70mm models forthcoming in 3" format, and possibly 100mm and 120mm examples as well.
All this in addition to the f/l's used more commonly by the amateur astronomy community.

Amidst all the mass production, relabeling, and mostly ho-hum external design so prevalent in the market today, it is nice to see the ideals of craftsmanship and design have not been completely forgotten.

Kinda looks like the promising reboot of a legend, from where I'm sitting.

:-D


A very reliable source in Europe reports that three 80mm units were sold there: two in Germany, and one in Spain.
Three 60mm models have also been sold to customers in Germany.

At $542 USD it may seem reasonable to collectors but still pricey IMO.

 

Mike

 

Well, the 48mm Brandon is $345, and even more on this side of the pond so not that far of a stretch, considering.

Agreed!  And much like the "Masuyama" followers, the Brandonites will have no issue's "Ponying Up".

So it's for long refractors and big SCTs with 2" focusers, I guess.

+1 too as it seems the 1st batch of 60mm are now sold out. Not certain about the dates of the next batch.

Oh my! I don't know what this means, exactly, but I'm getting a silly sensation right up in the amygdala. This will undoubtedly tax my marriage for some time if such plans come to fruition!!! And I better plan to part with every TeleVue that I own to soften the repercussions...!  :shocked:

While 100mm and 120mm eyepieces are interesting, either Barry or ES should make a 60mm wide field in the 3 inch format.  That eyepiece would be useful in a lot of more common f/8-f/9 scopes and would still be great in the slower ones.  While they are at it, someone needs to either make 3" UHC or O-III filters or a way to attach 2" filters to the eye lens.

Dan Mcshane of DGM made 90mm dia VHT filters for my bino objectives. It can be done on a custom basis with any of their offerings. Dan posted about this several years ago.

Just out of curiosity, at NEAF I asked another filter maker based in NY about >2" filters. He said impossible I guess it depends on who you are and who you ask.

Mine delivered today.

 

I did quick look through it with FC100DL f/9.

I see vignetting in outer a few degrees.  

 

According to Ted@hutech.com, Masuyama 50mm/45mm 53 degree AFOV will be released in June.

I think you have it already with a Tak cover.

I wonder if the 2016 Masuyama 60 & 80 are same as vintage Celestron Ultima 60 & 80
