Expression of interest: New TMB Planetary Type II eyepieces
Hello everybody,
I might be able to get my hands on several new TMB type II planetary eyepieces of 6mm and 9mm.
From the TMB website:
"The TMB Optical® eyepieces are the first long eye relief eyepieces with a comfortably wide field that have the sharpness, contrast, and lack of lateral color and light scatter for planetary observing of the best orthoscopic and Plössl designs. What they don’t have is the ortho and Plössl’s limited eye relief and restricted fields. The six-element TMB Optical® eyepieces provide a substantial 58° field of view with high contrast, a tack sharp view, and surprisingly long eye relief for relatively unvignetted eyeglass use."
I would like to know who would be eventually interested in getting some.
The price would be $49 + shipment.
Please express interest by PM only.
Thanks for reading.
Yes I will ship anywhere in Australia, but not overseas.
Postage to Melbourne would probably be in the $5-15 range. It is to cover the shipping cost itself + handling.
Thank you for your interest.
Jason, I would appreciate if you would consider promoting/selling your eyepieces on a separate thread.
I do not work for anyone and I am not a shop either!
I am an amateur just like you or anyone else on the forum.
I have sent you a more detailed answer by private message.
Hi all, just a quick message to let you know that my 6mm arrived in the mail this morning. It was well wrapped. So all is OK David because you did seem to expess concern (rightly, THX for looking out for us). I'm happy to say that "Phiber" is good as gold.
Will do a direct comparison of the TMB 6mm vs the TV 6mm radian.
And I'll post the results as soon as the clouds dissapear and Jupiter pops into view!
I've had a 6mm for a few months now (obtained from elsewhere), and, ohhhh, it is soooo nice to use.
Such a long eye relief for such a short focal length EP, nice wide FOV so the drift time is so much longer than with anything else I've used. And the image quality is so fine- I haven't noticed any ghost reflections either with the Moon or Jupiter.
And on GC's, man-oh-man, nice and bright and tight star images.
I just can't wait for a clear night to give this one a fang...
The 6mm gives me 333X on my 17.5" dob- too much for most instances. This 9mm will give me 222X, much more practical, but still requiring good conditions.

thanks sylvain,fast delivery,good value..6mm jupiter,very nice...regards mac
Hi all
Finally had a chance to do a comparison between
the TMB6mm and the TV Radian 6mm.
Just to clarify my vision is quite poor with astigmatism of 2.5.
Yet I prefer to view without glasses as I consistantly see more without them.
Tonights targets were an almost full moon and Jupiter.
Telescope TOA130 fl1000mm so 167X.
First thing I noticed was a greater sky darkness with the TMB, maybe the TV needs a clean. There was a nice moon off the limb of jupiter. Details were lovely with both EP's and my poor quality vision was unable to destinguish between the two. The field of view with the Radian was slightly larger I thought. The TMB seemed more contrasty. I preferred the Moons shadow creased limb with the softer Radian. Jovian details seemed easier to spot with the TMB. But it was all pretty much of a close call.
Conclusion: Very impressive for a $50- eyepiece, especially when compared with a quality Televue EP 5 times the cost. My poor vision couldn't tell them apart
With a couple of days hindsight I would like to add that the TMB seemed to be easier to focus well. The Radian produced a similiar quality image but was harder to fine tune. The Radian does have more bells and whistles with the adjusting collar and optional astigmatism compensation lens, but I've never bothered with that. I still find that with my poor vision I usually out perform the casual observer due to my many years as an amateur astronomer. You kinda learn how to look to max what you see.
Clear Skies

Reason: typo
I finally got a chance to give my brand new 9mm a thrash.
I chose my 8" f/4 scope for this knowing that if a particular f/ratio would show any short comings, an f/4 would, making sure it was as well collimated as possible. This scope/EP combo gives 90X neat.
1: Jupiter was first of the rank. Oh, how nice. Nice banding and all four Gallilean moons on show. Moving the moons to the edge of the FOV, the very last 5% started to show the effects of coma, and a tiny amount of astigmatism right on the very edge. I doubt this would be obvious in any other scope of a slower f/ratio. It was only noticeable by really looking for it. Diffraction spikes from the spider were visible only radiating of the bright planet.
2: M7 was low in the western sky, depriving me of its full potential. Still, WOW, nice bright stars all the way across the FOV.
3: 47Tuc- now we're talking. BAM! So many stars! Spectacular resolution, and at 90X nearly the full extension of the GC filled the FOV. I pulled out my 2X barlow, man-oh-man! Still pin-point stars, and the entire FOV totally packed with the massive cluster. The effects of coma were not noticeable with the barlow.
4: NGC 253. As I had suspected, Sydney's sky has gone to the dogs big time in only one year. I had wanted to use this particular scope as the test scope for sky conditions to compare contrast with my open truss scope. My worst suspicions where realised sky wise, thankfully not scope wise. NGC 253 became easier to make out with this TMB Planetary 9mm with the darkened background sky glow. Variation in brightness was noticeable with a brighter core and fading elongated disk.
I am really impressed with this EP. A worthy addition to my collection, and a as good a stable mate as the 6mm I already have.
Thanks, Sylvain. I am in no way disappointed, and all my expectations have been met with this brilliant eyepiece.
Mental.
PS- I forgot to mention the eyerelief: huge.
That is another great feature of these TMB Planetary Type II's, the fantastic eyerielf means much more comfortable viewing as you don't need to sit your cornea on the eye lens to both see into it & see the entire FOV.
Another feature of these EPs is they have a twist cap sleeve. By giving this cap a twist, you raise and lower the rubber eye cup to the most comfortable position for you.
Love it!

Sam, they should be there soon. I have PMed you the registered post number, in case
Anyway the registered post insures the shipment for $100 - the total value - should there be a problem, which I am convinced won't happen as I take good care of preparing tough packages.
I am happy with my eyepiece and the price. I have not had chance to use it for astronomy but I have used it to look around terestrially and it is better than a $129 eyepiece I have. I for one would be happy to hear of other bargains Sylvain hears of.
WOOO my eyepieces arrived an hour ago. Very well packaged, bubblewrapped and taped, only took about 4 business days. Hopefully i can get to use them tonight if the conditions are right (knowing my luck they wont be)

x2, mine arrived today too. I am looking forward to some clear skies
