Baader Genuine orthos apparently have same design and shape as the UO H.D. Abbe orthos but much more improved multicoatings yielding superb transmission and contrast. We have compared them to the legendary Carl Zeiss Jena Abbe Orthos 1,25" and the TV Plössls on the gas giants: the Genuines performed a hair better than the Zeiss Orthos and the TV Plössls!
Funny I missed this comment. Now I may just have to find out myself if the Baader is on par.

So, the Pentax XWs are the best planetary EPs? It may seem obvious, but I have so little knowledge of the astronomy world lingo I may have miss interpreted something.

Hi Star Gazer, I think you missed Daniels last line, " . . .the Televue plossl represents the pinnacle of the planetary eyepiece world to me, thus making them my favorite planetary eyepieces of all time."

Hi Star Gazer, I think you missed Daniels last line, " . . .the Televue plossl represents the pinnacle of the planetary eyepiece world to me, thus making them my favorite planetary eyepieces of all time."
This is what I read and why I was asking.
PENTAX XW - Now these series of eyepieces are a killer. Never in all my years have a seen a wide field perform like one of these. I carefully tested the 3.5mm, 5mm and 7mm against the other eyepieces in this review mentioned above and it cleaned them all out, including the reputable Tak LE 5mm in every manner. The XW represents the pinnacle of the wide field planetary eyepiece arina and was also a cut above the T6 in both surface contrast and light scatter upon careful examination both in the 14.5" Starmaster and FS102.
And then I read this.
I do find it sad that Al Nagler doesn't have the TV plossl produced in various 1mm focal length differences starting at 4mm but regardless, the Televue plossl represents the pinnacle of the planetary eyepiece world to me, thus making them my favorite planetary eyepieces of all time.
That is why I thought I might be missing something.

Me, too. There was the original eval and then there was this update.
I think he revised some of the things he said in the original in the update.

He says the Pentax XW is the best "wide field planetary" eyepiece, but the TeleVue Plössl is the best "planetary" eyepiece. To get the wide field, the eyepiece usually has to sacrifice a tiny bit of sharpness at the center, so at the center, and under the best conditions, the TeleVue should be better. Under most conditions, it may be hard to tell, and the extra field and longer eye relief of the Pentax might be more important to you.

Star Gazer,
Although this report is very informative, and represents all the eyepieces in a respectful way, its just an opinion for observers to take in when deciding on there next eyepiece.
The Pentax XW's are fantastic eyepieces. I had em all.
They may be the best "Wide Field Planetary" eyepieces. But you would have to like widefields as planetary eyepieces for them to be the best overall.
Its a personal preference that no one can choose for you, but you.

Dan,
When are you coming to the planetary viewing wonderland of sunny Forida. Maybe this would be the best place to test some of your eyepieces.

I've got an Idea! Give me your Pentax and Naglers eps for some exhaustive testing. Please allow for a few years duration, and I'll have the answer and get them right back to you

Random note - to whoever said they see a little "yellowing" in Tak LE's compared to UO HD orthos, I agree. I compared the 18mm LE with the 18mm UO HD ortho and the UO had slightly better contrast & truer colors ("whiter").
Something I just discovered is that the 5mm and 7.5mm Tak LE's have always been listed as 5 element eyepieces by vendors. However, if you go to TNR's home page, they have all the LE eyepieces listed as "new" equipment, and they state that the 5mm and 7.5mm have 6 elements, not 5. So it should not be a surprise to see a cleaner image in good 4 element eyepieces.
However, the 5mm and 7.5mm have that 52 degree field and excellent edge correction. So when I"m using my alt-az mount, I use the 5mm LE, but when my big scope is on the equatorial, I'll use my 5mm and 6mm AP SPLs, or UO HD orthos. The Tak LE line is an outstanding all-around set of ep's though.
I"ve talked to a few people who dislike the "whiter" appearance in ep's like Zeiss orthos, AP SPLS, Supermonos, etc. Everyone has their own preference. Personally, I consider the "whiter" ones to be "reality eyepieces". If I want to see a color-filtered view of the planets, I'll add my own filters.
There will never be an eyepiece that suits everyone, that's what keeps these forums going!

Hi,
My very recently bought 5 mm TAK LE has 5 lenses: "not surprising since the Masuyama is Tak's Father " (?? = quote from a "parallel" cloudy nights thread)!

Hi, Scott.
I wonder if 3 group 6 element design is only for
Tak HI-LE 2.8/3.6mm? LE 5/7.5mm is still 5 element design?

The 5 and 7.5LE are five elements and the 2.8/3.6LE are seven elements.

I am not Dan but I just left for Florida on the 26th and got back on the 1st. We went to Ft. Lauderdale first for a baseball tournament and then Orlando to Disney World. It rained every afternoon, sprinkled every evening, and was cloudy every night. Someone must have bought one HECK of a new scope somewhere in Florida.

Hi Daniel,
Managed to do any critical comparisons between the Baader Genuine Ortho and the UO HD ortho?
I found a review (more like observation of the eyepiece behaviours) on the web and it tallies with what I observe about the Baader Ortho. I have no chance of comparing the Baader ortho with a UO HD ortho and I am curious if there is any difference in scatter and contrast. Perhaps there is a slight difference.

Nice report. I tend to agree with your comments on the Orthos. I have seen nothing out there yet that, for planetary purposes, makes me want to replace the ones I have.
