TELEVUE ETHOS 10mm TELESCOPE EYEPIECE: WORTH THE PRICE?

[@LarryNaylor-zq9rj]

Very interesting video. Out of my price range but I could always win the lottery. You have a great talent to explain things on a easy level. I would think That 10mm might have a curse on it 😳

[@tsulasbigadventures]

@@LarryNaylor-zq9rj Thank you. It sure seems like it

[@keithcharles2113]

So glad you got it back!

[@tsulasbigadventures]

Thank you!

[@HumbleLife8]

GOD Bless you Tsula, I was looking into getting the 8mm Ethos, I already have the 9mm Delite but there is something about the Ethos 100 Degree Field of View that just adds to the experience. thank you for sharing yours! keep them videos coming we really enjoy them!

[@tsulasbigadventures]

@@HumbleLife8 Thank you so much. The Delite is a great eyepiece too but yes there is just something about looking through a 100 degree FOV.

[@lindafinch8983]

Hi Tsula, I delighted to hear you recovered some of your equipment ! Hats off to that sheriff!! This is a really interesting comparison and after your experiences, we know just how durable this lens can be! I would love to buy “Newton” an Ethos at Christmas for deep sky viewing, but as you say, it is a very expensive eyepiece, so I will have to save up! Thanks as always, for your well informed comparison, it’s good to know what you can expect from an item before investing so much money! PS..Love your Fox mug! I’m wondering if you like foxes too, or is this because Tsula is cherokee for fox? Thanks for staying up so late to give us this really helpful information your hard work is very much appreciated 🤗🌙✨

[@tsulasbigadventures]

Hi Lynn: Thanks. Well, I hope Newton gets what he wants at Christmas. Not only because Tsula is fox in Cherokee but also because I love foxes that friends and family always give me fox themed gifts for my birthday and Christmas. This adorable fox comes around my meadow in Montana very often. He/she loves to catch mice in the meadow. So that little fox is very welcome any time. I have some great photos of that fox with a gorgeous bushy tail sitting close by on a rock. Take care. Wishing you clear dark skies.

[@lindafinch8983]

@ How wonderful to have a fox on your meadow! Fellow fox fan here, when I went to England, a fox joined me in the garden briefly, while I was looking at the moon, such a beautiful creature. Happy stargazing 🤗🌙✨

[@ultrametric9317]

You've discovered that nothing beats the simple Ortho for planets! :) The secret is that it is SO easy to place your eye. Like looking out a window. I have a whole case of ultra-wides I almost never use. I prefer the simple eyepieces for everything.

[@tsulasbigadventures]

The ortho is great for planets but for me there is nothing quite like looking through a 100 degree FOV eyepiece on things like star clusters.

[@stephenc2738]

100 degree FOV requires one to roll the eyes about, I prefer the 10mm Delos. Another option is the 10 mm Pentax -XW

[@Youtuber-ku4nk]

I agree. I also have the Delos 10mm and it is absolutely fantastic and so so sharp and the AFOV is very good - better than I expected from the spec 72 degrees.

[@tsulasbigadventures]

@@stephenc2738 I like rolling my eyes around

[@oscarsabitni]

Thanks for the review. The comparison is best. I like how you weave your commentary with amateur photos of the objects.

[@tsulasbigadventures]

Thank you.

[@PieceofPeace]

I have an Apertura AD8 dobsonian and can't decide between the 10mm Ethos or the 13mm Ethos, I'm just filling in my eyepiece collection now so I want to make the right choice

[@tsulasbigadventures]

@@PieceofPeace For a telescope with 1200mm focal length I think you would get more out of the 10mm.

[@iamjessieray]

Another nice video, I like these kinds of comparisons where you are comparing eyepieces of a similar focal length and use case. I would have to look through the Ethos before I could ever justify buying it, but the other options you presented are great information. I have a 10mm Orion Plossl, which I bet is exactly the same as the Mead you have there. I might have to see about that Baader though for planetary or very small objects.

[@tsulasbigadventures]

Thank you. I was pleasantly surprised at how well the Baader performed.

[@brenthann2623]

Great video. I can’t believe someone would steal your astronomy equipment. I also can’t believe you recovered it.

[@tsulasbigadventures]

Thank you. It was a miracle. I didn't get all of it back but I was so happy to recover any of it at all.

[@PauI__]

In Europe we have wayy bigger prices on Televue eyepices but sice Baader is german we have good prices on Baader stuff. Right now Moepheus is on sale for the equivalent of around 230$. The question is in terms of optics how is Mopheus comparing with Ethos, leaving aside the fov difference

[@curronhill2744]

In your conclusion, how does the Morpheus compare to the Ethos for general views and clarity to the edge?

[@tsulasbigadventures]

@@PauI__ My Morpheus 9mm is excellent but I felt it was unfair to compare since it wasn’t the same size

[@charlesstrang2346]

Great review. Love the coffee cup

[@tsulasbigadventures]

Thank you!

[@ronm6585]

Thank you Tsula. Great comparison.

[@tsulasbigadventures]

Thanks, Ron.

[@christopherhamm1574]

Good morning! Another great video. No question that Televue makes great products. Aside from outstanding views they are extremely well crafted and durable. I like the Baader products too. And I must admit I own quite a few Meade 4000 series Plossls. I am mostly a planet/ Moon observer. My go to eyepiece is a Televue 8-24 zoom I purchased in the 90’s. A few years ago I also purchased a Baader 8-24 zoom to fit a spotting scope. But haven’t really had much opportunity to do a side by side due to busy schedules and somewhat waning enthusiasm to stay up late. Thanks again for putting together a very well done video. Clear skies Chris

[@tsulasbigadventures]

Hi Chris: Good to hear from you. I have always been afraid to try a zoom eyepiece. Years ago I had a spotting scope that had a zoom eyepiece that was terrible and ever since then I just had this aversion to them. Someone else told me that I should get a zoom lens and that they are much better now.

[@knarf9335]

​@@tsulasbigadventuresI have a Celestron 8-24 zoom and find it to be my go to eyepiece. I mainly observe deep sky with my 16". It is a useful contrast adjuster. I can zoom in to darken the sky to find the sweet spot where the object shows best. Full disclosure, the only competition this eyepiece has is assorted plossels and a 5mm TMB.

[@tsulasbigadventures]

@@knarf9335 Thanks. I’m going to look into that one.

[@stebecool]

Hi Tusla, any chance you could get your hands on an SVBony 68 degree AFOV eyepiece to review? It would be super helpful to hear your take on it as someone who regularly uses high end equipment to see what you think of the quality of these. They’re very popular these days, seems like everyone has them. I have the whole set of them and love them. They’re very inexpensive, about $30 each

[@tsulasbigadventures]

I am sure I could but whether I need them is an entirely different question. But let me look into it. I really love the Explore Scientific 68 degree FOV. So, maybe I could compare the SVBonys to the ES ones. Stay tuned.

[@knarf9335]

Have you ever considered buying, borrowing, or renting a PVS-14 night vision device for evaluation? I would love to see your trademark in-depth, perspicacious analysis of this very interesting device. They are expensive, $3,000-$4,000, but a lot of astronomical equipment is pricey. Most amateurs now focus on astrophotography and night vision is primarily a visual aid. You being a self proclaimed visual observer, well the conclusion implies itself.

[@tsulasbigadventures]

@@knarf9335 woe! That is expensive! I have to research it and find out more

[@johnathanedwards8706]

Wow, I didn't realize your car accident was so serious. You look great. I hope you feel ok. I own a 10mm 1.25" Meade MWA 100 degree AFOV eyepiece. It is fantastic. Of course they don't sell them anymore. I'm looking for a 11-13mm Jupiter eyepiece if you have any recommendations. Thanks

[@tsulasbigadventures]

@@johnathanedwards8706 You mean just to look at Jupiter? The Televue 11mm plossl is great

[@internalmegat]

Amazing content as always, I'm grateful I found you in this maze of the internet, you should be more mainstream then you are currently. I will definitely consider that eyepiece.

[@tsulasbigadventures]

Thank you so much. That is very nice of you to say.

[@Youtuber-ku4nk]

Also consider the Tele Vue Delos 10mm. It is a newer model and is as sharp as the Ethos, but has better eye relief and adjustable eye cup. It costs half and weighs less. The 72 degrees afov is still very big.

[@bofblog]

Very nice comparison, worth testing them on Jupiter as this week a new disturbance in the South Equatorial Belt

[@tsulasbigadventures]

@@bofblog I tried to look at Jupiter last night but it was very cloudy and 32 degrees which combined with the waxing gibbous moon ended my observing early. Sounds interesting. Hopefully I can catch it another night. Thanks

[@helpdeskjnp]

Glad you got your stuff back! Idiot thieves haven’t a clue of what’s valuable and I’m glad they didn’t trash it!

[@tsulasbigadventures]

@@helpdeskjnp thanks. He was very rough with my mount that the sheriff recovered but incredibly it still works

[@snapfinger1]

Are you familiar w/ the 1882 optimal viewing of the Transit of Venus ? :)

[@tsulasbigadventures]

@@snapfinger1 There were some photos of it in S&T.

[@jimcabezola3051]

Whew! I'm relieved you got SOME of your stolen astronomy equipment back. Given that this 10mm eyepiece was also returned to you, I hope you make very frequent use of it. That eyepiece has been through the ringer. Now...let its gaze rest...on Saturn's rings..or any number of ring nebulae (sorry...I couldn't help myself). Much aloha and deep, dark skies to you!

[@tsulasbigadventures]

Hi Jim: Thank you. I was thrilled to get some of it back. Of course, the criminal threw out my notes and sketches but at least I got a fair amount of other stuff back. Aloha to you too.

[@leoncorns1450]

That's a special eyepiece anyway you look at it or through it.

[@bjdiss]

Did you recover your observing log that was stolen?

[@tsulasbigadventures]

@@bjdiss No. the criminal threw that out apparently

[@hugadogstudio]

Hello, Tsula! I presume your conclusion regarding planetary observations here should be marked with an asterisk that there is no much benefit from Ethos in this case only if your’re observing with go-to or some other kind of tracking mount. Otherwise huge apparent FOV makes a difference not requiring constant RA adjustments. But it’s probably save to assume that an observer considering such an expensive eyepiece is not limited by manual-tracking-only capabilities of her or his scope’s mount 😎🤗

[@tsulasbigadventures]

@@hugadogstudio I didn’t think about that. Good point

[@Youtuber-ku4nk]

Tsula you should just use a red light for camera light in your videos in general. It almost hurt me to see your night vision ruined every time you talk to the camera and have spend time regaining night vision 😊

[@helpdeskjnp]

I thought the same thing. However, upon further reflection I think she was just using that time to summarize what she found, and was more for showmanship than when she was actually comparing them.

[@TheStarHound]

I earn a nice standard of living, but I am also budget conscious. The higher end TVs always give me sticker shock. I have owned Baader eyepieces in the past. The Planetariums are excellent eyepieces for the money.

[@tsulasbigadventures]

@@TheStarHound It’s kind of embarrassing that I own such an expensive eyepiece but it sure is nice and so are the Baaders.

[@matt1234link]

That's a tall drink of water there.

[@perry92964]

i have that same aspheric eye piece, i paid 14 dollars for it from svbony i cant afford those expensive ones even used just a side note svbony does make much better eye pieces then that one

[@tsulasbigadventures]

Sometimes you can get very nice eyepieces for not too much money.

[@lostinstarryskies]

Oh, that's so lucky....the jerks probably had no idea what the heck they had stolen and what to do with it.

[@tsulasbigadventures]

You're right about that. The criminal couldn't figure out what the mount was so he just dumped it into a bag. Fortunately it still works even after he roughed it up.

[@Astronurd]

Nice eyepiece but doesn't merit the price. How can you include cheap starter eyepieces among the comparison

[@tsulasbigadventures]

@@Astronurd I said they were the ones I owned.

[@tsulasbigadventures]

@@Astronurd And another reason is that the viewer who asked me to make this video told me that I should forget about those expensive wide FOV eyepieces with lots of elements and instead use some cheap Kellners. I totally disagree.

[@JoeJaguar]

Thanks for your comparison Tele vue our top of the line I do have a 13 mm naglar and meade 4000 uwa which are 82 and 84° fields of view, but I have never bought ethos. I just feel what I have is good enough and that extra 18% and changing all of my eyepieces just not worth the huge cost would be in the thousands if I replaced everything You’re correct in saying the 10 mm ethos wasn’t any better on the planet viewing what you get is a larger field of you and better corrected to the edge I know in my video that I just did a couple days ago I mentioned is a tele vue Plossls better than a good regular Plossls And I said they’re probably virtually gonna be the same Cheers

[@tsulasbigadventures]

@@JoeJaguar Thanks. That sums it up well.

[@A0111.]

These Orion 10mm eyepieces (and theyr siblings 4mm, and 23mm) are made of plastic and appear under different brands, you can even buy them cheaper than from SVBONY, but I don't recommend them, as they can be easily scratched, and 4mm is just awful.

[@tsulasbigadventures]

Do you mean the aspheric eyepiece? I hardly ever use it because I have much nicer eyepieces but it provided a good comparison to the other eyepieces.

[@A0111.]

​@@tsulasbigadventures, yes, sorry, I thought I am adding my comment to where someone already mentioned this aspheric eyepiece.

[@markmeridian3360]

Perhaps a more appropriate comparison would be the view you get of an object when you can just fit the whole object in the field of view. A wider FOV eyepiece can be used at a higher magnification and still see the whole object. Also, the differences between eyepiece designs is often more pronounced when you're using shorter focal length telescopes. I would be very interested to see you repeat your test with a faster scope (F4 to F5) and describe the difference in what you can see on objects that fill the FOV between the 10mm Ethos and a 20 mm Ortho or Plössl. I didn't want to spend the money on Ethos eyepieces so I bought a Tele Vue DeLite to try (62 degree FOV vs. 100 for the Ethos) The views were significantly better than my other eyepieces gave on objects that filled the view. It was enough of an improvement that I gave all of my other eyepieces away and replaced them with a set of DeLite eyepieces. I imagine the comparison would be even more favorable for Delos or Ethos eyepieces.

[@tsulasbigadventures]

@@markmeridian3360 OK. Let me try this out with my 10” DOB which is f/4.7. That’s as fast as I own
