I find the Delites and Delos are color neutral with very good contrast. I have tried many of them and would recommend the 7mm Delite.
A 7mm will give you ~ 213x and of course the eye relief is close to 20mm.


Let me further clarify on the above recommendation for your driven 12"dob.
EP powers ranging from 200x to 225x is a sweet spot for me. If you go below this I find it difficult to look at significant details on planets, thereby an 8-24 zoom, although will be good on most nights of avg seeing will show me too little. The opposite is also true, whereas you go with too much magnification, lets say 250x and above, most nights of avg or poor seeing will not allow you use the EP, therefore a 3-6x Nagler zoom and any EP in this range would be too much power.

It just so happens that you canget a 7mm delite used for less than $200. If I'm not mistaken, there is one in the classifieds now.

I'm also a big fan of zoom eyepieces for planetary. Especially on nights with average to mediocre seeing (aka most nights) they let you crank up the mag when the sky steadies periodically. The Baader zoom would require a barlow or powermate, as even the 8mm lowest setting would only be 187x in your 1500mm scope. Personally, I have a distaste for barlows/powermates as I don't like physically long eyepiece chains it creates. For this reason, I'm trying to save up for a powerslide with rapid switch barlows for my dob.

All 82 degree eyepieces are 'junk' for planetary detail, unless you like soft and fuzzy views. If you can't afford Delos by Televue or Pentax XW's try used Radians also by Televue. They go for around $150 and there are a lot for sale and they sell fast. I have not found anything under $150 that can match the above three.

And i'll raise you most of the Burgess/TMB's planetarys{$40-80 used} to the Radians

Ive had bothlines ,still have the TMB's
To MY eye anyway IMO
I absolutely agree with ya on the 82's

I have a 7mm Nagler Type1 and it is anything but soft and fuzzy. As sharp as any eyepiece I have looked through.

A lot of great recommendations above but I'll add a vote to the Delos. I have the 10mm and it is absolutely superb on every scope I use it on.

So many options, and all of them wrong, except one. If only I knew what it was.

If you want orthos, get an 18mm, 12.5mm, and 9mm along with a good quality, 3x Barlow (Orion Tri-mag?). People have good things to say about the University Optics HD/ Fujiyama series, though I didn't like the lack of contrast in the 7mm (they didn't blacken the edge of the eye lens). Takahashi orthos are excellent, and more comfortable to look through. The combination gives you 85x, 120x, 165x, 250x, 360x, and for those extremely rare cases, 500x. You can also use the 12.5mm and the 9mm and use just a 2x Barlow for a more limited range.

I'll add my voice to the zoom cheerleaders. A Baader zoom will give you views to 185x. A 2x Barlow will extend that to 375x. The optics are first rate. Not that great for glasses wearers.

Pentax XW, Televue Delos, and Delite, and Baader Morpheus all can be used with glasses.

In the 60° field eyepieces, the ones below 15mm are an excellent value, and are comfortable, but mostly too short in eye relief for glasses. 3.2mm is good for exceptional cases, and 4-5mm for a more general purpose high power.

Finally, I don't think the super-duper wide fields are as sharp as some of the narrower angle eyepieces, but I have to wonder at the extra color you are seeing. If you are seeing it at the edge of the field and not the center, your are encountering lateral color. No, it's not good, but you encounter that a lot with wide angle eyepieces. If you are seeing spurious color on your planets in the center of the field, you are encountering the earth's atmosphere doing a number on a low planet. The solution is to get rid of the earth's atmosphere, not your eyepiece.

For planets I like to be very comfortable, so orthos are out for me, at least in larger scopes where the true field gets tiny.

In my 12.5" F5, I use a paracorr and typically a Leica zoom + 1.8 barlow. That gives 185 - 369.

Besides that I particularly like the 7mm XW on Saturn. I have yet to try that set up on Jupiter, however.

My Naglers indicate otherwise when the seeing allows. Best views I've had of Mars have been with 7mm Type I and 5mm Type 6.

Same reason I don't use Plossl's under 10mm anymore (that and they weren't any sharper than the Naglers...so why give up the field of view and suffer miserable eye relief?) By comparison the 3-6 Zoom eye relief is still comfortable, despite having a Plossl width field.

Hi all,
I'm looking for some suggestions for planetary eyepieces. I currently have some Naglers that are great, but the sight coloring around the planets is bothering me. Eye relief is more important than field of view, and budget wise I'm willing to save up for a quality eyepiece. These would be used in my 12" f4.9 dob, but Id like to pick up a 4" refractor in the next few years as well.
Thanks,
Charles

Use my Vixen SSW's 10mm with binoviewer on 4 and 4.7" refractors. I prefer them to pairs of T6's 9mm with cooler color and it's easy to see the field stop. Transmission is excellent. Favorite is Jupiter, where they are slightly cooler and IMO just as sharp as Delite 11mm. BH or Ebay have them on special quite offen for $250 vs. 350 list. The 7mm are a bit less comfortable, but still very good. Clear skies Pete
