best binocular for viewing milky way
      #6030411 - 08/17/13 07:53 AM

What is the best binocular for viewing the milky way, the overall structure with star and dark clouds from a dark site ( 21.5 mag/arcsec^2) ?

I am presently considering the Nikon Action EX 7x35 with 9.3 degree FOV or 8x40 with 8 degree FOV, the Kowa 6x30 with 8 degree FOV seems to be to narrow (48 degree AFOV).

with many thanks in advance

Thomas

Both Nikons should do fine, but you may find the 9.3 degrees of the 7x easier for the larger objects.

I use 7x42's with an 8.6 degree field for Milky Way cruising and find it much better than the 8x binos I also had. With the 9,3 degrees you will be able to see context and asterisms much better than with the 8 degree field. Anything bigger than ca. 8.5 degrees will do very well for your intended viewing.

I picked up a pair of Nikon's Aculon 7x35's with the 9.3 degree FOV. Very good for the money, and GREAT for wide field views of the Milky Way!

For me it's definitely a case of a preference for seeing the woods rather than the trees, but not at the expense of poor edge performance ruining the experience.

My most enjoyable views have been through Zeiss 7x42 with 8.6 degree TFOV, laying flat on a poolside lounger for a couple of hours either side of midnight in the Balearic and Canary Islands.

I'd cast my vote for the Nikon AE 7x35 9.3* FOV.

A wide 8x40. May I suggest a Swift Saratoga MkII

Kenny,

Some of your past endorsements for your 7x42 Dialyts contributed to me embarking on the same route. Absolutely wonderful experience cruising the Milky Way with my Zeiss FL 7x42's. Tried to find a nice pair of the Dialyt version but did not succeed, so settled on the new Victory FL's after a few months. Delightful binos. Such an involving, bright relaxing view. Unsurpassed for the MilkyWay!

I have a pair of those Nikon 7x35 but they're not my first choice for viewing the Milky Way's bright and dark nebulosity. Of the binoculars I have, I actually get the best views with my 15x60. More detail, better contrast, you get the picture.

If I had regular access to pristine skies I would own a pair of 10.5x70 for this particular purpose. I had a 7x50 in the past and for viewing dark nebulosity, the large exit pupil does deliver quality views. I would not go both to a smaller exit pupil and to a smaller aperture.

For panning the milkyway in general I like the blue planet 2.3x40 Galilean opera glasses (advertised 28 deg TFOV and near zero eye relief). 2nd choice 7x40 Orion UW 14 deg FOV. Neither are made in the US anymore. Vixen Ascot 8x50mm UW are pretty god too for handholding.

I have the 7x32 Orion Expanse with 14 deg FOV but did not know there was a 7x40 version made in the US . When were they made in the US ?

I agree with Mark, a really great view with a 10x70! I have the Nikon 10x70 6.5 degree field and it is absolutely immersive for sweeping the Milky Way and a lot of dark nebula like Barnard's "E" near Altair just pop in these and the area just off the spout of Sagittarius' teapot is amazingly textured.

Way more impressive than my 9.3 degree Nikon 7x35 or Celestron 7x50 Nova.

As can be divined, there is no one perfect binocular. For any task. Ask 10 people and you'll get at least 9 different recommendations. And any one person's tastes are almost guaranteed to evolve, too!

For the Milky Way, the widest field at the selected magnification is desirable. You must first decide what magnification and exit pupil you like. The aperture follows.

For a first bino for this task, 7-8X will serve well. Personally, I'm quite happy to suffer soft imagery toward the field edge if it buys me more field of view. My argument? If for a wide angle bino the central 50 degrees is as good as that for a narrower field bino, that extra outer field, even if aberrated, is a bonus! After all, with a hand held instrument you have no need to gaze toward the field edge. Let your lower resolution, highly sensitive outer retina utilize the outer field.

For such a vast object as the milky way, you'll appreciate a large apparent field.

I have a pair of 11x80's that are by far the best binocs I have for deep sky viewing, but for wide field views of the Milky Way, my little Nikon 7x35's do better. Different tools for different jobs...

I couldn't agree more. Though I'm still looking for the "perfect night sky scanning" binocular. I've always been partial to my Super-Wide 7x35s, but recently I've purchased 3 Super-Wide angle 7x50s just to see what they might do for me (other than add weight!)

I completely agree and I don't understand how anyone can disagree.

An aberrated field is better than none at all.

It's a complete no-brainer.

If an aberrations of the outer field were preferable to no field at all, then why do manufacturers even bother to do anything about rectifying them?

One would that thought a great portion of the considerable price of the more exotic eyepieces from TeleVue was precisely due to the minimisation of such.

But.. smaller, fewer aberrations are better than bigger, greater aberrations.

My own thinking is that there is no one best binocular, best scope, for viewing the Milky Way. The Milky Way has many scales, there are large scale details that may not be visible in a 1.6 degree TFoV but there are somewhat smaller scale details that will be visible in that 12 inch scope with the 1.6 degree TFoV but not seen in a pair of binoculars with a 9 degree TFoV.

For a given true field of view, the highest magnification, largest exit pupil is best... This translates into the largest aperture with the widest AFoV. Mel Bartel's 13 inch scope is F/3.3 and with a Paracorr and a 21mm Ethos provides a 1.9 degree TFoV.

Because it's better to have an aberration-free outer field than an aberrated outer field.

Given the choice of an aberrated outer field or no outer field at all I would take the aberrated outer field every time. Wouldn't you?
