Why anyone wanting a planetary ocular yielding an 80degree. Field of view is beyond me when an ocular often 1/5 the cost will handedly outdo it tho I guess when you love wide angle deepsky its too easy to throw the same ocular on planets . They aren't as good though. I know this raises some dust in here but I'd refer you to Daniel Mounseys EXCELLENT review on eyepieces best suitable for lunar and planetary observing. It was one of the most realistic. Common sense this gs I've read on the topic.

My own experience tells me my Televue plossls and UO Abbe and HD Orthoscopics are excellent. Too my Televue Barlow's are amazingly transparent. Perfect, no but so good it s amazing.

I have a UO HD Ortho 12mm that I barlow (200x) and Powermate (250x) at times as well. A couple reasons I would (and do) use wide fields on planets:
1 - Less nudging in an undriven scope
2 - Comfortable eye relief for those that need it

Point 2 is moot when the exit pupil is small enough that an observer's astigmatism no longer interferes.

Not having a tracking mount and a f8.6 scope the Ethos come in handy. My 8mm gives me 110x a .9mm exit pupil and 2 minutes of sharp view before nudging. For a closer view the 6mm gives me 147x a. 7mm exit pupil and a 90 second window.

With these two eyepieces I am not bothered by floaters, don't need to rebalance or use a finder.

Syed,

Thanks for the advice Mike! It is probably because I switch from observing DSO's right to planets.


DSO and planet observing don't mix ... at least not very well. IME, if you want to optimize either, you have to do without the other. Or maybe you could divide the night into a DSO phase and a planet phase. That is what some experienced observers do.

Mike, thanks for your tip about using Photopic vision for observing planets. I have noticed that when I leave my kitchen lights on and go directly out to the patio to observe, the sky looks darker and the brighter stars look better?

So in general, use day vision for the Moon and brighter planets for better contrast?

Thanks,

bob

I agree with you that in my 102 refractor my TV 8mm and 11mm Plossls, in concert with the TV 2X Barlow give great views of the planets. However, my scope is on an undriven alt-az mount. Constantly having to adjust the scope's position limits the amount of time I can actually view the object. The wider FOV of the ES 82* 6.7 and 4.7 and the WO UWAN 4 allow for more drift time so I can spend more time looking at the object and seeing detail as the atmosphere settles. Even though I don't wear my glasses when observing, I also find I prefer longer eye relief than I get from the Plossls.

On a driven mount, ZAO II's, TMB Supermonos and my Pentax XO 5.1 are truly tough to beat for my viewing habits.

Undriven, Ethos and delos / Pentax XW series do pretty darn well considering the number of elements.

Dare I say it - when observing planets, I use a 9mm Kellner and a 5mm Circle-T Ortho. Both are 965's are both are Japanese. I have many good newer eyepieces but nothing I have seen will beat these on planets, especially the Kellner, which is my all-time #1 on Saturn. Obviously, I only use these on planets and in long scopes. GW

Now that I have a new barlow on the way, I can just barlow up my 7mm XW to get me 220x, 311x and 336x Or, I can use the barlow on my 10mm XW to give me 215x or 235x! So now it is GOODBYE to my 5.2m Pentax XL for a 21mm XL instead !!!

Yup. I feel that the 21mm XL should do just as good, plus all I have to do is trade mine up for it.

Some offbeat choices:
Nagler 7mm Type 1. Razor sharp just like VT ortho but wider field, longer eye relief. Can be barlowed 1.8x.

Generic 9mm Or. Also razor sharp and white tone.

Short scopes: 6mm AP SPL / 6mm Brandon / 6mm UO checkered plossl (this is a real sleeper and approaches the brandon!)
Great for the Moon!
Medium scopes: 7mm TMB Supermono, 8mm Brandon, 8mm TV plossl
Nice on Jupiter!
Long scopes: 7mm Meade RG Erfle (isn't it actually a konig?), 9mm Supermono, 12.4mm Meade RG WA, 12mm Brandon
Killer for Saturn and Mars!

I find no compelling difference between any given good quality eyepeices.

These days, the best eyepices for me for planetary viewing are the ones my Binoview that match seeing conditions.

If it were me and I had another Televue 101, I would use the Televue Nagler zoom with it for planets.

But for planetary, I would use the 10" with a binoviewer and some decent plossls giving the highest magnifications for your seeing conditions.

For my C14, I have been using some Hyperions in 24mm, 13mm, and 17mm, some 19mm Flat Field Orions, some 15mm Vixen NPLs, and some AT 20mm Plossls.

I just pick the pair that gives the best view, and that depends on seeing.

My seeing conditions generally support up to about 250x, but 340x sometimes if I stay out late enough for seeing to settle.

Eddgie,

I fully agree on the binoviewing thing. I tried one last year and it was the BEST for planetary. With two eyes everything just looks bigger and your view is 100% relaxed. I remember from last year as though it was just yesterday. I used a WO binoviewer in my Orion 127mm Mak that I had, and the views of Saturn were stunning! Plus, I had tracking on my mount which made viewing a real treat. :bow:

If I were considering becoming an avid planetary observer, and nothing more, I would definitely choose binoviewing for sure!!! I still might pick another one up for my 10" reflector as well!

Cheers,

The 10" Dob and binoviewers are my top pick among my scope setups for serious planet work.

Now yer talkin' :thewave: :watching: :watching: ! That would be perfect! Less nudging too! I'm not finished with binoviewing by any means! I'll be picking one up when I can for sure! :bow: The drawing you made, (your avatar), is 100% proof that binoviewing is excellent on planets Mike!

That avatar is my proof of concept for binoviewing planets. :ubetcha: The proof is in the pudding. The topping on the pudding is the fact I was binoviewing Jupiter with a lowly pair of Orion ED-2 22's when I made the sketch!

This has been my message for the last six months. Any pair of even decent quality eyepieces used in a binoviewer would be preferable to me than an expenisve "Planetary" eyepeice.

I just don't find the difference between good qauality eyepeices to be all that, but I increasinly find that I am getting better planetary views even with a relativly inexpensive binoviewer and even some fairly inexpensive plossls.

But to the OPs question, again, my own feelings are that for a 10" scope, a nice selection of decent plossls to match magnification with seeing conditions are all you need.

It is better to have some small steps between maybe 180x and 250x to get the best tuneing.

And a good choice might be the Baader Zoom for this in the 10" scope. That would make dialing in the right magnification very easy.

Bino viewers don't do it for me because I have one good eye and one not so much. My favorites for planetary detail are my Ethos, Delos, T6s, XWs, LVW and WO UWAN. I just got a Kasai HC ortho but haven't been able to try it yet. David

I agree also on this. However, I still prefer the single eyepiece solution because it is less complicated. So I gave up the binos and instead prefer the expensive planetary :p
