3x Barlow for my new 80mm Apo?

I currently use an 8" SCT, F/10 2000mm focal length.
I just ordered a W.O. 80mm Flourite Doublet , F6.9 555mm
My higher mag. eyepieces are good quality 16mm, 12mm, 11mm, and 9mm ortho and plossls. I also have an Ultima 2x barlow that will give me about 124x when used with the 9mm on the new refractor.
My question is rather than buy a couple of higher mag EPs, should I consider a Tele Vue 3X barlow? What are the pros and cons? I bought this new scope for wide field views, and I'm not much of a planetary observer.
As a side note, how well do Type 6 Naglers barlow? I've been considering a 13mm T6.
Thanks,
David

If you want to save a bunch of bucks, and still have fantastic performance, get a University Optics 2.8X Klee Barlow. Equals or exceeds the Televue Powermate.

I use a Vixen FL80S quite a bit (it's an 80mm F8 fluorite doublet). You would be surprised at just how good the planetary views through these little scopes can be. I would stick with shorty type barlows or the TeleVue Powermates since the longer type has a tendency to hit the diagonal mirror. I use an Orion Shorty Plus 2x which works quite well. If you can stand the short eye relief I would just get a standard U.O. 7mm ortho to fill out the high powers. Another option is to get an Apogee Super Easy-View 3.6mm eyepiece. I have one and it works great (it has a built in barlow at the bottom of the eyepiece).
The 13mm T6 is a superb eyepiece, my favorite for widefield/ deep sky views with the 80mm F8. Highly recommended but keep in mind that you may need a TeleVue Powermate to keep it from vignetting. I use mine witn the Shorty Plus but it does vignett the edge of the field just a bit.

Personally I would stick with a 2x barlow and go with some shorter focal length eyepieces with reasonable eyerelief. A 7mm Nagler would be nice.

Note that Ultima Barlows are considered to operate somewhere around 2.3X so that 9mm comes in at about 140x and a 7mm would be about 180x.

Note too that if you place the barlow in front of the diagonal, it changes from a nominal 2x to something around 3x so you really don't need another barlow.

The real strength of an 80mm APO is not high power stuff though, it is lower power widefield so it seems to me that is where you might want to evaluate your eyepiece collection/selection.
