Hi everyone. I was wondering what you would recommend for the planetary observer with the Tak f/9 DL. I'm thinking about both EP options as stated in topic. What are your thoughts and/or experiences? The TV zoom is less expensive, but is the quality the same? Thanks very much.

Ken

The quality is the same.  The only difference is eye relief and FOV.

I was never a fan of the Delites but they do have a strong following. 

As for direct comparison, I haven't done that but I strongly prefer the Zoom for it's variable adjustment (in between Focal length).

Okay - thanks. I might try to cancel my order for the 3 and 4 Delite and just order the zoom. Looks like the way to go.

The zoom is my most-used eyepiece with a 100DC. I have absolutely no complaints; you'll love it.

Thats the path I took, went with the Delites, then subbed in the Nagler zoom at the short end. Saved some money and space in the case. Wish I could compare them together.. perhaps one day..   I think eventually I'll look at the short Ethos, to get the added fov.

I don’t think I’ll ever be without a Nagler 6-3mm zoom EP.  I’ve had one in use for a little over 15 years.  The ability to change FL quickly to adjust to seeing conditions is a priceless feature to me.  It’s my most used double star, planetary, and lunar EP for my refractors.  I’m sure there are better, short FL EP’s, but IMO none are more versatile and easy to use.

Interesting, you buy a Tak refractor, but don’t consider their eyepieces? Not saying TV is bad. But Tak makes some outstanding planetary eyepieces.

I have the Nagler 3-6 zoom, and have made repeated comparisons with Tak 6mm ortho, and most recently TOE 4mm.

 

Neither of those beat the NZ, and they don't zoom.

 

Only other difference is that the NZ has a yellow tone and the Taks are neutral.

The Tak TOE ones look pretty good also, not just the TV's

My Nagler 3-6 zoom is my most used eyepiece in my 105mm APO on double stars and the planets.  The small 50* AFOV is not a problem with a clock drive.  The ability to zoom to the best power for the sky conditions is huge, and not having to refocus when zooming is outstanding!

The zoom gives you the "wrong" magnifications. At f9, there is nothing more to see past 4.5 mm.

I'm glad I went with the 3-6Zoom, and have never looked back.  A sharp, and very easy to use eyepiece, truly a great value.  I haven't even used my Abbes much since getting the NZ.  I've occasionally been curious to try a DeLite, or even Delos, but honestly my guess is they're going to be close enough in performance to my Ethos that I'd be better off buying a 2X Powermate and a 6mm Ethos if I went that route, and I know that's an awesome planetary combo especially in a dob.  For me it's just not worth the hassle buying or messing with my eyepiece lineup.

And that's why there are so many variations and spreads of eyepieces, no one eyepiece can meet everyone's needs.  For the NZ, at f/7 and f/8 it's just perfect.

Tak turret & 3, 4, 5, 6mm Delites. And you have a great accessory for other combinations as well.

I use the 3 - 6 zoom with my Celestron Ultima SV Series 2x barlow on my Stellarvue 105T at powers of 250x to 500x often on the Moon and Double stars.  At 250x to 375x is where I do most of my tight double star observing unless the seeing is poor.

 

  I live 13 miles from the Pacific Ocean on a 450 foot hill and often get good seeing, so I guess it depends on you're location and seeing conditions.

Solar systems objects are the reason I bought the DL. I have my SV and some nice panoptic EP's for wide field.

This all makes a lot of sense to me. But with a 100mm scope using a 3mm Delite, I'm at 300x or 75x per inch. In excellent seeing conditions, is that magnification reasonable?

Yes, if the scope has excellent optics.

Possible yes,  frequent, no.

More reason for the TVZ as it can be backed off to match max magnification allowance.

I'm a Tak FC100-DL owner as well. The Nagler zoom is very often in use with my scope. My other high power eyepieces are Pentax XW's which are also really good but the flexibility of the zoom is just so useful for quickly finding the "goldilocks" magnification and tweaking it as the conditions / target changes.

Build quality is the same, not the optical.  DeLite surpasses the Nagler Zoom in most every way (at least to my eye):

  • More eye relief
  • Larger AFOV
  • Sharper on-axis (crisper, more defined image)

I went through several Nagler Zooms, both 2-4 and 3-6 looking for one to use in the planetary role, but none produced an on-axis view anywhere near as precise as fixed focal length planetaries.  It is nice, and convenient that is for sure, but you pay for those as nothing is for free and for every take you have to give something.
