I have seen the total Veil with a TV pronto, 35mm panoptic, and O111 filter on one occasion with dark skies at out clubs/state park dark site

In my experience, the Veil is better seen in any telescope with a nebula filter, regardless of the darkness of the sky. I regularly see the Veil in a 3 or 4 inch refractor from skies where the Milky Way blazes overhead. From my urban backyard, I have seen the Veil in a vary of instruments including a 4 inch but always with a nebula filter.



I see the Veil in my 15x60 binoculars without filters when the Milky Way is just barely starting to become visible.

It's worth remembering that telescopes and binoculars cannot increase the surface brightness of an extended object like the Veil over naked eye, they can only make it larger



Yes but with binoculars you can almost equal the naked eye surface brightness, which you can't with a telescope.

My viewpoint is that the things a pair of giant binoculars does better than a small refractor are of limited interest when there is significant light pollution, i.e. suburban skies.

The big, low power views are most engaging when the skies are dark and clear.



But in case you can't avoid the light pollution and still want a big low power view, binoculars do this a lot better.

I see the Veil with a 10X50 binoculars with two 2" filters UHC in front the binos., in suburbs skies., 9,5 field.

It likely depends on the level of the light pollution, personal preference and the scopes/binoculars in question.

Does one spend two hours continuously scanning mag 4.8 skies at 15x-25x? When the skies are light polluted, the ability to magnify the image to pick out details and zoom in on interesting regions is what I find most enjoyable.

Spotting the bright green NGC6572 is possible at 20x but viewing its nature requires 100x or more.

This is one advantage of a low power refractor in a grab and go situation. In practice, at least in my case, a bino with a larger dob covers what I need pretty nicely. Or in a grab and go situation, a bino with a grab and go C90 does it pretty nicely as well. The bino is really for low power, scanning the terrestrial or the sky purpose, and it does the job very well. It is only a companion tool to a real telescope.

My experience with fork-mounted Apogee RA-88's might be indicative of what to expect of other big binoculars in urban environments.

I observe exclusively with the 32x eyepieces, which yield a 90' field in the RA-88s. Sarasota skies are very bright, but when the humidity is as low as it has been during this last week, averted vision will show stars in the 10.1 - 10.4 range in these binoculars, even though the naked eye only sees to mag 4.0-4.5 due to sky glow.

This makes for some very satisfactory star-hopping.

From my perspective, the important things are comfort while viewing and a solid mount. One can get by with less than perfect optics, but a sore back or neck will "get" you every time.

Not quite idle speculation - "generic" post titles frequently invite replies after a decision by the original poster. This also happened with the more recent "Thoughts on the Celestron Skymaster 20x80" thread.

Of course, I wonder if the thread has been read. However, the additional reading can be interesting.

size does matter
today, in my mag 4 + suburban skies, I looked for Comet ISON
it was humid, the comet was low
with 100mm binoculars, I could see something there, just barely
with 150mm binoculars, I could clearly see something-still faint, fuzzy, not much form, but large and could ID as the comet

is it foolish to have such large binoculars in such poor skies-maybe?
is it cost effective-no?
but I can see better

In some sense more equipment is always better, there is something one can find to do with it.

On the other hand, in this situation, I have to think though that it would have been more easily seen in a larger telescope. It is a matter of context. If one only has the 150mm binos, they are going to be better than the smaller ones. But if one has a 12.5 inch, it would be a better performer.

I would not recommend buying a pair of large binoculars jut to view comets from suburban skies.

Your Mileage May Vary

bright comets in large binoculars are fantastic, but this one is not-yet

Binoculars do a great job on comets, IMO. Let's hope ISON can live up to all the hype...
