It would appear so! 'Speculation mode' is on though.




A long long long time ago, I had a lengthy conversation with an insider regarding any real differences between the UO HD and BGOs. They did indicate to me that both were from the same source, just branding customizations done at the factory. Since branding customizations by a factory can go into things beyond logos into things like polish and coatings, I also pushed on that point. While not saying it specifically, they alluded to no difference. I've had both brands, although not at the same time. Felt they were pretty equivalent based on memory and observing notes.

My experience with them was supurb. Several of the Masuyama's that I tested are the very ones that Carol photographed for this thread, so I know that she has good ones. I had owned in the past the bulk of the original Tele Vue Plossl series, so I know that the Masuyama's are capable of matching or exceeding them in several areas, though not in contrast. As I have stated before, it seems to me that many (to most) people judge eyepieces purely by their contrast alone. Things like width of "true" field, flatness of the field, freedom from lateral color, on and off axis resolution, ergonomic comfort in viewing, ergonomic comfort in Barlowing, and the like generally play a distant second fiddle. Most will on non critical evaluation say that the eyepiece with the most contrast (pop) appears more "sharp" to them. Perhaps, but sharpness is an essentially arbitrary blend of contrast with resolution, so sharpness is not at all a well defined term, being almost purely subject to what the beholder values most as a building block for "sharpness".

Thanks! They are, indeed, a beautiful design. I'm very, very fortunate to have them.

Guess I'm the only one, or at least one the few with a less than stellar review of the illustrious Masuyama?




I don't think you are the only one. But true that as a general observation most people praise the original Masuyamas. I think this is indicative that overall the line is excellent and probably quality/consistency very good.

Not sure on the 10mm you mention, but my experiences with the 7.5mm were similar to yours in that it had what I considered to be moderate levels of scatter (which could have been from a poorer scratch-dig as you mentioned), and it was also not as *crisp* on planetary as other similar focal length eyepieces I have (like Lawrence mentioned, sharp is a term which often gets misinterpreted, so I prefer the term crisp as it I think better implied a mix of drivers whereas shrpness can often be confused with resolution which can have a rather specific meaning). For the longer focal lengths however, they were simply spectacular on star fields putting up some quite impressive and *moving* views. I would love to find that 25mm 65 degree unit Carol has, must be a real gem I also find the conical eye cup a very interesting design. When I used them it felt odd for the shorter FLs in that the cup seemed to be made to fit my eyeball, sort of like I could place my eyeball in the EPs waiting socket. As odd as it was, very effective in stopping stray light. Very unique housing design. I like it!

Very interesting, that the 25W is the only Masuyama with 65°. the majority are 52°

Their observatory class eyepieces (4" monsters) are 3 element Kellners.

Interesting reading this. My first experience with Masuyama was with the 10mm and it left a lasting effect, which I'll never forget. Compared to everything else I tried and had at the time it made me realise how important quality is and the effect on performance. In my case it easily outperformed the Ortho's of the day (UO, etc, various Plossl's), though it was never stacked up against really serious competition, like Zeiss Ortho's or Supermono's or Pentax SMC Ortho's. I didn't realise how much difference there could be and this 10mm Masuyama was the start of real progress for me in image quality.
Must stack them up against more serious contenders and see how they go. I am reasonably confident the Masuyamas will hold their own overall, but maybe I'm speaking prematurely.

This has been discussed quite a bit but I've never seen anything more than assumptions that the coatings on these are different. My opinion is that the eyepieces, which obviously have the same optical elements and identical metal housings, are in fact, completely identical except for branding/engraving. Just because Baader may use ad copy such as 'Phantom Group Coatings' (or whatever they call them) doesn't mean that the optical house is coating the Baader units with a better quality coating. For one, the UO HD coatings look really excellent - not sure what improvement the Baaders would be able to offer. I could be wrong, I just don't think so. If this mystery is ever definitively solved I'll be glad and if I'm wrong I'd have no problem saying so.

Yep, if I was in a better position, I would have been very interested. Came up at a bad time for me.

'Scuse me, but...if the Baader is a "Genuine Orthoscopic" wouldn't Ernst Abbe technically be the "designer"? I would think of Dr. Masuyama (or anyone else basing their work on an existing design) as a "adapter" rather than "designer". Of course if the Baaders really are *not* genuine orthoscopics, I suppose Masuyama could be the designer rather than an adapter, in which case I think the Baaders are mis-branded.

Regards,

Jim

I think you're safe. Unless there is some obvious difference that you can see or test for, which AFAIK, there is not, neither Baader nor UO would be sure of exactly what their competitor is getting. The factory knows, but yeah, like they're going to say. Not gonna happen.

This keeps coming up and I know many have said that there are differences between coatings, polish, etc. in the UO vs. Baader but I have never seen one shred of evidence that it is so and I don't believe there is any difference. I am not at all pointing to the poster here - simply noticed the post and wanted to ask again if /anyone/ has /any/ evidence of an actual difference in quality of these two brands. Even the coatings 'look' to the eye to be of the same color.

EDIT: I had forgotten that I already commented on this but still it is an occasional topic that comes up. I think Bill's post earlier is the key - someone who should know basically told him that there is no difference between these two. If I paid this optical house to engrave 'super duper best quality coatings' or 'phantom coating group' on my personal run of 250 of the UO HD/Baader orthos I am pretty sure that they wouldn't object.
