Your favorite eyepiece for planetary detail
      #5534524 - 11/22/12 09:53 PM

What is your favorite eyepiece for planetary viewing? Right now, I'm using a 10" SCT, but plan to invest in a TV NP101IS

Our 11mm T6 is our best for 170x most the time. No tracking. The 82* even lets us scan. ES would be good, too.

That's like asking which of your children is your favorite. Not Fair.

That said, when I'm looking at planets, I find myself reaching for my Brandon 6mm far more often than any other.

Pentax:
5XW, 7XW, 10XW (have 14-40mm but too low for most details I want to see)
5XO - fills the spot where a 5mm SMC would be; also acts as a 'ZAO-II 5mm' (since there isn't one)
6, 7, 9, 12 SMC orthos (have 18 but too low power for details)

Zeiss:
ZAO-II set + Zeiss/Baader 2x
25 aspheric micro ep (superb contrast)+ 2x Zeiss Barlow
ZAJ set excluding the 4mm, 8mm

Docter 12.5 84deg AFOV (on 'never sell no matter what' list)

For me, it depends on the telescope and the conditions, these are far more important than the particular eyepiece I am using.

If the seeing supports 400x, I need first to be using a telescope that is performs well at 400x and then I will choose the appropriate eyepiece. The 25 inch, that would be the 9mm Nagler, in the 12.5 inch F/6, the 4.8mm... In the 12.5 inch F/6 it would be the 4.8mm Nagler, in the 12.5 inch F/4.06, the 3.5mm...

Since when in city all I can enjoy are the planets, I use all my eyepieces on them. I consider as planetaries my BGOs (I prefer the 18 and 12.5 with Powermate 2.5 over 9 & 6 for eye relief), Delos 10 & 6 and Radian 8. Baader zoom is also great, it shows almost what the other show with a bit of lateral color sometimes, but it gives me the perfect magnification everytime, as is or barlowed.

Leica ASPH zoom, in all three telescopes. It beat out the Pentax XWs that I had, and was the equal of the ZAO IIs that I had on loan. It's nice to be able to dial in the right magnification to match the seeing.

5mm XO = 155X in AT111EDT. Perfect magnification for Jupiter and Saturn in my skies. I have other well (LVW, TMB SMC), but nothing can match the snap focus and detail in the XO (although the TMB SMC comes close).

What is your favorite eyepiece for planetary viewing? Right now, I'm using a 10" SCT, but plan to invest in a TV NP101IS




Unfortunately, what will work good in your SCT won't even be a candidate for planetary in the NP101 because of the radically different focal lengths. A 5mm eyepiece in the SCT will get you around 500x and in the NP101 only 100x. So the planetary choices will be quite different.

Magnification and exit pupil should be considerations in the choice, as well as what your local seeing conditions will allow on most evenings, and on rarer evenings. For me, the local seeing usually allows 200x most all the time, and then more rarely 400x. So that is my working range.

I also find that a .75mm exit pupil is a good working max for maintaining good contrast. Not a hard-fast rule but just what my eye tends to like. In the NP101 that exit pupil would be produced by a 4mm eyepiece (135x). In your SCT that exit pupil is produced by a 7.5mm eyepiece (330x). But that magnification is a bit high so if you back it down to 200x then the SCT would be using a 12.5mm eyepiece. Bottom line is that the SCT, due to its larger aperture, will having working planetary eyepieces between 12.5mm to 7.5mm or even 6mm, whereas the NP101 will likely have a working range starting at 4mm then getting smaller, probably down to 2mm on the very rarest evenings under very dark conditions since the view will be dim using 2mm.

If it were me, I would be looking for 3 eyepieces for the SCT, probably 8mm, 10mm, and 12mm. Without getting exotic, an 8mm and 12mm Brandon, then need to find some suitable eyepiece near 10mm, so perhaps an 11mm TV Plossl or the older 10.5mm smoothsided version. Going exotic would opt for the 8-10-12 TMB Supermonocentrics or AP-SPLs since they both come in those focal lengths.

For the NP101 the 2-4 Nagler Zoom gets you the focal length range you need in one eyepiece, so something to consider. Another thing you could do would be to get the 8-10-12 trio for the SCT, then get a 3x Barlow to use those same three with the NP101. This way save some money by using the Barlow to get to the shorter focal lengths that the NP101 needs for productive planetary. Yes, not a purist approach for planetary mandating a Barlow, but it works good enough and IMO a higher class planetary, like the Brandon, when Barlowed will at least be the equal of the 2-4 Zoom in terms of how detailed the image is.

A final consideration is to think about operating ergonomics. The NP101 shines as a rich field telescope with its very short focal ratio. In that role you are likely to be using very wide field eyepieces with some good eye relief. So the switch to a tight eye relief narrow FOV planetary may not "feel" like a great transition. So the better tactic from this standpoint would be to perhaps get some wide fields with good reputations for planetary also and then Barlow them for the NP101. So in the 8-12mm focal length range you could assemble some Pentax XWs or Delos to fit that also.

Lots to consider...most of it driven really by personal preferences.

7mm and 9mm UO ortho. My generic 12mm Japanese vintage ortho I got with a scope is super sharp, it surprises me all the time. Great on Jupiter in the C11 when the seeing won't tolerate the 9 or 7 mm. My 9mm UO was only OK until I realized the field lens was very dirty and the field stop was not in the correct place. It had a lot of scattered light and a fuzzy field stop.
It's great now. I mean it was DIRTY... a film and dirt. blew off the dirt and used 91%Iso with dist H2O. It may become my favorite now. Have to say my 17mm TV smoothie is darn good too.
My award goes to the underdog 12.5 generic Ortho for now.

I have an NP101, and for planetary viewing find the 2x Powermate invaluable. Here's my two primary planetary observing sets:
(1) 7mmT6 Nagler, 5mmT6 Nagler, 2" 2x Powermate
which respectively give (magnification, exit pupil):
7T6: (77x, 1.3mm)
5T6: (108x, 0.96mm)
7T6 + 2xPM: (154x, 0.65mm)
5T6 + 2xPM: (216x, 0.46mm)

(2) 4.7mm Ethos; 3.7mm Ethos, 2" 2x Powermate
4.7E: (115x, 0.87mm)
3.7E: (146x, 0.68mm)
4.7E + 2xPM: (230x, 0.46mm)
3.7E + 2xPM: (292x, 0.34mm)

Obviously, the 3.7E + 2xPM pushes the scope a bit over its recommended "true" magnification limit of around 250x, as well as producing an exit pupil problematically small for many people. The 5T6 + 2xPM or 4.7E + 2xPM are at the realistic useful limits most nights, or even just the 3.7E by itself on really mediocre-minus nights.

If the scope is undriven, the 3.7E and 4.7Es keep planets within the FOV luxuriously long, and therefore easier to pick up fine detail from extended uninterrupted study than with the Naglers. For my tastes, in an undriven NP101 a narrower-field EP (e.g. 50deg AFOV) would require annoyingly frequent nudging in the magnification ranges useful for viewing planetary detail.

I've been through Baader GO's and University HD Ortho's and a 5mm TMB Supermono in the past but I'm very happy with my current line up and see them being with me for a long time

Depending on the conditions, in my 102 f7 I like a 2x Barlowed TV 11mm Plossl, and straight through ES 4.7 and UWAN 4 mm. The UWAN hits a sweet spot for me at about 178x. I've had some really nice views of Jupiter over the last couple of weeks with this eyepiece.

When I had my TV101 I used a 4mm Radian or a 3mm TMB a lot but honestly it was not a big enough scope for planetary observing for me personally. I just could not tolerate the tiny exit pupils required for planets.

Don 't know why you would want to do planets with such a small scope when you have a 10".

I Used the 4mm Radian more though. 180x In a 4" scope made the view grainy and dim.

But whatever trips your trigger.

So far I've used the Baader Hyperion 8-24mm zoom with a 2x Barlow. It allows me to find the planet more easily and then easily determine maximum magnification for viewing.
Still really new at this, might change my ways of doing things with experience. The last few times out conditions were poor so views were terrible regardless of eyepiece in use.

I've not yet bought my first Brandon EP yet, but last night I did a comparison on Jupiter and the Moon between all of my 5-10.5 mm EP's (BGO, RGO, RO Konigs ) using the 100/1300 Carton. The 7mm and 10mm Russell Optics Research Grade wide angle Konigs came out the clear winners, beating the Baader and Meade Orthos providing noticeably better contrast.

With a 16" F/12: 17mm Ethos and, infrequently when the seeing is really good, the 13mm Ethos. They seem as good as the UO HD Orthoscopics. Though, every now and then, I still try to see if the orthoscopics are better, but they haven't shown themselves to be even though they have fewer elements.

Of what I still own, I would have to say 7mm T6 and 10.5mm XL, on their own with SCT when conditions permit, and with TV101 with alternating between 2x and 3x TV barlows and a 2.5x powermate.

That being said, I am amazed at how well the ES100 14mm and 20mm perform on planets in the cassegrain with the 2x powermate, like a match made in heaven. A bunch of glass, but a very good view of Jupiter.

I notice glints with the XFs, but otherwise, the comfort makes up for it, so I like those too.

7.5mm ultima (or clone) is nice too, 5 element japanese.

I used to use antares and UO flat top orthos, but the fov and tiny lenses eventually caused them to sit in the case. As soon as I sold them, I realized I made a mistake, but only in that I did not ask a higher price... I can't deal with short ER on eps that have lenses that are too small to clean easily, and not about to have my eyelashes removed, they serve a biological purpose.

What Bill said about the SCT vs NP101 is totally true. When I was considering selling my televue 3x barlow, I decided to keep it and it now lives in the case of the 101. A GOOD barlow or powermate makes more sense to many, than a premium eyepiece that is not useable in all scopes. Televue is a GOOD barlow. I have 2x, 3x, and 2.5x and 2x powermates. Considering a 5x if the price was right. Having only 540mm focal length at f5.4 actually makes a 5x practical as low as the 10.5mmXL. Next time I see one in the $100 range (but not so old as to not accept the t ring), I will probably snatch it up.

With the 8" dob, the XW 10 & 7 with TV 2x Barlow and TV 2.5x Powermate for powers 120x, 171x, 240x, 300x, 343x, 429x. The XW 14 + Powermate fills a gap with its 214x power.

Also planning on using my newly acquired ES100 9mm + 2x GSO ED Barlow for 267x and less nudging in the dob.

I have two favorite planetary eyepieces: My two 25mm Zeiss microscope eyepieces, together with my Baader Maxbright binoviewer. I use them on all my scopes. Refractors from 60mm to 150mm, C8 and 12" f/5 dob. I change magnifications by using a variety of Baader Glasspath Correctors, a barlow lens and extension tubes and Baader T2 and 2" diagonals.





I have never seen finer planetary details in any of my telescopes than with these two eyepieces and my Baader Maxbright binoviewer. All my orthos, including Zeiss Jena 16mm, 10mm and 9mm, sleeps in my eyepiece case now.


Clear skies!

...favorite eyepiece for planetary?

Pentax XW 5 (190X) and 7 (136X)...comfortable, clear and robust!

Planetary?

For Jupiter ~ My 5.2mm XL that I WAS going to sell to get another Pentax XW.....But I realized how excellent it is as a planetary eyepiece and am keeping it! it gives me 235x for Jupiter, which is excellent on most nights. When that power is too high, and conditions are not met, I will put in my 7mm Pentax XW @ 160x, which works on Jupiter every time! I also got rid of my 1.6x Antares barlow, which is excellent, but I needed another eyepiece, so I sold it only to just order another last night!

I don't mind using barlows on planets because you really don't have to switch out that fast because planets are bright and you can find them again. Galaxies at higher powers is another story and I find using barlows for higher powers a bit tricky because without tracking, your targets drift out of the FOV and gets lost at times.

So, for now I use my Pentax 5.2mm XL on Jupiter, Venus, Saturn and Mars when it gets big enough. I will go higher on Saturn and Mars, (270x-300x-370x respectively), when the skies are steady.

Cheers,

I have the same two you have Syed! Love 'em! Sometimes I will barlow up the 7mm @ 270x, (On Saturn) or the 10mm @ around 184x, (On Jupiter)!!! I also just picked up a 2" Lumicon Variable Polariser to use on planets as well, which I can now set to cut back the irradiation and color bleeding on the planets.

Yes Mark, the XW 10 & 7 are really great to have! Previously, I had the 20 & 14 only and didn't mind barlowing to get the 10 & 7 equivalents, but with the 10 & 7 native, I can barlow/Powermate those to get the really high powers desired for planetary viewing.

To cut down on the brightness of Jupiter and bring out some more detail I'm planning on using the blue color filter. I've used a moon filter on mistake thinking it was my blue filter, but the results were pretty nice actually.

If Jupiter looks too bright to you in an 8" scope, your eyes are not adapted optimally for planet viewing. Try looking at the reflection on a white piece of paper from a bright white flashlight every so often when you're observing. That will keep your eyes closer to photopic and give you better visual acuity, and Jupiter will not look so bright.

If the planet's too bright, your eyes aren't right.

IME, the best all around planet filter is a Baader Moon & Sky Glow. That's not to decrease brightness, but to increase perceived contrast.

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.

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,

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.

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

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

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.

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!

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.

However expensive the eyepiece, I see more with a binoviewer and dirt-cheap kellners and orthos, so I prefer the slightly more complicated solution, since it ultimately delivers more detail to my eyes. And it is probably less expensive in the long run, since I have stopped lusting for a large set of expensive planetary eyepieces in many different focal lengths.

I've thought about going back to binoviewing many times. I had a binoviewer years ago that I used with an SCT for planetary viewing. Now, however, it's a big project. A brute-force-and-ignorance approach with my lightweight Dob-Newt would be difficult to balance and might result in some flexure of the struts. Instead, I need to cut down the struts. I also need a new focuser, since the Kineoptics helical won't cut it for binoviewing. After I get done planning that work and and shopping for the binoviewer and eyepieces, I am exhausted and wondering whether it will be worth it. So I never end up doing it. I use a 5XO, generally, though not because it is supposed to be among the best, just because I like it. When I am not in the mood for the tight eye relief, I use my first-gen, deshrouded, baffled 6.7mm ES82, sometimes with a Barlow. I can't recommend it, really, but it works for me.

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 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




I am in favor of both of these ideas and it all depends on the seeing conditions or my mood. I usually prefer the binos, but I also use single eyepieces at public sessions. When I use the binos, I prefer pairs of Brandons, CZJ orthos, ZAO-II orthos, or A-P SPL.

When I use single eyepieces, it depends on how tired I am. If I am fresh, I can use the ZAO-II or A-P SPL. But if my eyes are tired, then I use a TV Radian or Pentax XW for their eye relief and comfort.

There is no single "best" solution for me and I am glad that decent planetary eyepieces are so plentiful.

Cheers,

Ron

However expensive the eyepiece, I see more with a binoviewer and dirt-cheap kellners and orthos, so I prefer the slightly more complicated solution, since it ultimately delivers more detail to my eyes.




Over time, as I tried binoviewing for several months straight, I discovered that the more complicated the process of observing became, the less I observe. But when I keep my primary scope on an alt-az mount, with just a red dot finder, and a single slot eyepiece holder with zero balance issues...taking the scope out becomes effortless so i end up observing way more than when it is complicated. Granted, there are nights when complicated is on the menu as may have some specialized needs that evening that have been planned. But as far as the "norm" I like my primary scope to have zero to do and just pick it up mounted and set outside for cooldown, then walk out with a few eyepieces in hand and get to observing where the only futzing I need to do is spin the focuser knob. Yup...I like basic lazy observing.

I found the same thing happened to me over time. I LOVED the views in binoviewers, don't get me wrong, but over time I would go outside, set up the scope for cooldown and when I got around to observing I would use eyepieces in mono mode! I also found it tiresome to set up the balance for the binoviewers, add the barlow, put binoviewers into the barlow, add two eyepieces, fiddle with focus for both eyes, etc....

It's a great view, but I am lazy too and like to keep things simple. I may foray into the binoviewer world again like I said....I dunno.

You just reminded me how much of a PITA it was to set it all up, Back then I had tracking too!

My favorites are the ZAO's in a MkV binoviewer, I definitely see more low contrast detail binoviewing. If the ZAO's didn't exist I could be quite happy with Radians, Ethos, or t6 Naglers for planetary observing.

I have my doubts that the Half-Hitch would work well for Mark's 10" f/4.8 Newt OTA. It's probably better for more compact loads such as APOs, short-tube achros and Cats. Also, there's that price tag: $1300. Ouch! I think that's more than I paid for my 10" Dob, 8" Dob and 150mm Mak altogether. But I'd probably get one for something or other if I could afford it.

The DSV-3 has a more conservative price, but it seems that it's also best for compact loads.

For all those complaining ... eh, commenting on the bother of hauling out the telescope with binoviewer and double sets of eyepieces, futzing around to make sure the eyepiece images merge correctly, and having to rebalance the scope, consider this: I have to do all that without a back yard or deck! The only place I can set up is in a public area beside my condo. Imagine the hauling, the futzing and the rebalancing without any privacy, while dog walkers, loitering teens and late-night sports fans stumble past, not to mention no protection from the glare of all-night lights of the paranoid neighbors. And if the night is cold, you can't go back inside for a break. You have to stay outside for the entire observing session to guard the equipment.

You folks have it easy! I'd be setting up that scope with binoviewer and all the trimings every clear night if had a backyard or a deck.

No, I'm not complaining.

I am too lazy to squint my left eye or cover it up, so I binoview.

Seriously though there is such a huge difference in the planetary image to me when binoviewing that it's worth the minimal amount of extra fuss. I think where a lot of people get frustrated binoviewing, is from using big, heavy eyepieces. Binoviewing with Brandons or nice, small, lightweight orthos or plossls is simply a pleasure - and my loaded binoviewers weigh virtually the same as my 31T5 Nagler.

I don't know how you do it Mike without having a nervous breakdown . I know I would..., and you know, light pollution would be the least of my problems. It's all the other things you mentioned that can spoil my observing.

IME, most folks who are not in the hobby are so night blind they would probably not notice the eye patch, much less the parrot, and might not even see you in the suburban "dark" unless they shine a flashlight at you.

Hi All --

Sooooo -- I guess I'll be a wild-card here because my 14inch LX200GPS is set up on a scope-buggy, ready to go outside from the garage in minutes. The Cat-cooler brings to equilibrium pretty quick and the binoviewer always has Brandons in it, for planetary (well and pretty much all) viewing. The best FLs for planetary viewing are the 24, 16, 12, (and 8 on really nice nights). These give 148X (11X/in), 222X (16/in), 296X (21X/in), and 444X (31X/in). The 24 gives really remarkable views. Jupiter's belts resolve into festoons and swirls and colored wisps with ease on a decent night. The Galilean satellites are disks with discernible albedo differences. With the 16 and 12 on decent to good nights -- the detail is astonishing. The 8mm in the 14inch is only for really nice, calm nights and then the views are pretty much in-orbit-around-the-planet.

Yes, I'm a devout Brandon acolyte. It is known. With a set of Bino'd Brandons in the 14, the views are pretty amazing and worth every second on a good night and even on the not-so-great nights here in Cleveland.

There you have it -- my bino'd cents

Howard

I agree! Using both eyes with two small eyepieces evewn with only 45 AFOV and not necessarily the best class eyepieces is far superior on planets than using one eye with a better class eyepiece. The gain using both eyes just can't be beat! It's also less tiresome staring at a planet at high power using both your eyes than using only your one best eye and covering the other. It feels unnatural to observe with one eye for long periods of time.

I have all the BGO's from 6mm to 18mm. I had a complete set - including pairs of the 9mm and 18mm for binoviewing. But I recently sold my BGO 5mm when I picked up a Pentax XO 5.1. I'm hanging onto the rest of the BGO's unless I acquire another eyepiece at the same focal length that is clearly better.

Brandon 6 vs BGO 6? BGO 7 vs Faworski 7 vs XW 7? Too close to call for me. I'll probably keep all of those.

They are both the same Kasai eyepiece. Antares and University optics also brand or used to brand them, but bottom line is we are talking about the same flat top orthos with all of these.

Three months ago I bought second hand an old SW 120mm ED refractor, hand picked and tested from TS, for a ridiculously low price.

So,I decided to buy( for the second time) the Nagler Zoom 3-6mm for 150X-225X for Jupiter and 200X-300X for both Mars and Saturn.I believe that the 120mm ED and that little zoom are made for each other ,as the magnification factor and the per inch mag ratio are spot on for the specific planetary targets..

A bit better on Jupiter than the BGOs and Brandons I used to own.It's worth mentioning though that this is not the impression I was under when I used it on the SW 80mm and the 100mm.

The BGOs were more pleasing to the eye for some reason that I have yet to determine what it was.The same amount of detail was visible in both though.

I don't know if it makes any sense , but I have noticed that TV eyepieces perform better when used on telescopes of 5"+ than when they are used on something smaller.
