I sky tested the binoculars a few nights later and they performed very well.
L. Olson
True, the mounting is not exactly adeqaute for the sheer size of these binoculars but they still work if you're careful and have a steady tripod.

Instead it was a collection of roundish rainbows that had me back in the house after a few seconds.

BACKGROUND:

I am an amateur astronomer and Vice President of the local Astronomy club. I own

several pairs of large binoculars and have looked through many more. My needs were

beautiful images of deep sky objects at a price I could justify. The Celestron 25x100

Skymaster Binoculars meet those needs.

GENERAL COMMENTS:

The binoculars arrived July 2004 and had a collimation error of about 1 degree (very

bad collimation). Celestron support was contacted at the request of Amazon support

and confirmed what I already knew, factory repair was required. I lacked the skills

and equipment to collimate and refill with nitrogen. Amazon promptly picked up the

broken pair and delivered a new pair in just a few days. What a difference a few days

made. The new pair was packaged inside a secondary box and arrived in pristine

condition. Daytime collimation was excellent. We tested the binoculars after

astronomy club on a distant lighted sign and found them to be essentially flat to the

edge of the field of view with a minor vignetting at the edge. Everyone was impressed

and several members wanted a pair. During the club meeting I suggested that

everyone who wanted a $500 pair of binoculars for $250 needed to go to Amazon and

purchase one before the price went up.

I sky tested the binoculars a few nights later and they performed very well. I had only

about 20 minutes till the clouds took over. Due to the high humidity and generally

poor observing conditions we were unable to use the binoculars for an extended time

and get a really good test.

I have been using these Binocs for about 6 months now and find them a genuine joy everytime I bring them out. On a recent autumn evening from a hotel balcony overlooking a golf course I was able to take in a marvelous variety of deep space objects. The sky was fairly dark- but by no means out in the country- and I saw the beauty of M4, M8, M20, M26, M16, M13,M31, M27,... and more. These are definitely Astro binoculars. They do need a tripod. You focus each eye individually. And there is some fade out in sharp focus as the eye reaches the outer edges of the field of view. This is not something I get worried about for $250. Maybe $1250. I have a Sunpack heavy duty photo tripod that goes for about $80 at Best Buy, and I use the Sunpak adapter to attach the Celestron. It is NOT the sturdiest set-up, but I found that I put the tripod into some very warped positions (one leg sometimes) and walk it around for better views. I can fit the entire Plaeides into the FOV and the view of the Orion Nebula shows nearly the entire swrd. Glorious!! And one more thing- because the eyepieces focus individually, you don't have to worry about collimation issues. I had ordered a Skymaster 15x70mm that were so out they gave me a headache to look through them. I did get another pair, however, and they were fine.

I don't know why Amazon has this listed within Toys- it's one heavy toy. Educational and fun, but not for a child. Just wanted to note that as a safety issue.

It is a good binocular for the money. I have a 4 inch telescope also, but this bino has wider angle and is easier to stargaze. When both eyepieces are set on a wider view, I am getting double vision. Maybe my eyes, or out of collimation. When eyepieces are closed where you only see one circle with both eyes, then there is no problem. However, the most important thing to know is that you must have a heavy duty tripod. If I had researched in advance that a heavy duty tripod is a real must for this bino, I wouldn't buy it. Because those tripods can cost more than the binocular. After researching and testing the tripods at the photo shops, I finally bought "Slik Pro 700 DX" tripod on the net for $140. It was indeed a good decision.

The other comments on the mounting screw having a lot of play are very true. Tighten all you want, duct tape might work better. The magnification is strong enough that, after 6 months, I found a tripod to be mandatory. The Celestron recommended tripod added to my frustration. I never thought that something as basic as going to a point in the sky and having a steady view would be such a chore. The biggest gripe I have with these binocs is the chromatic aberration. With daytime use this isn't noticeable but a few stars or a planet against a dark sky and it is a significant problem. I expected some aberration at the edges, after all these aren't $3,000 binocs, but what I found was I had it dead center. Recently I had a great view of Jupiter with 3 moons visible. I was hoping to spend several minutes taking in the sight and seeing if I can make out features on the planet. Instead it was a collection of roundish rainbows that had me back in the house after a few seconds.

I received these well-packaged binoculars in record time from Amazon. In time for the March 3 lunar eclipse in fact, which was "first light" for them.

Upon unpacking them I noticed that the internal part of the binoculars (as viewed from the objective end) was less black than I'd hoped and believe necessary for good performance. I could clearly see threading that seems to extend all the way down to the eyepiece end. Areas within the threading are almost shiny, metallic black - other parts are grayish. Rather than suppressing internal reflections, this lack of consistency promotes it.

I have a sturdy tripod that I use for large-format photography that I knew would be more than enough support, however the tripod attach point on the binoculars is itself affixed to a round bar running the length of the binos. No matter how tightly I torqued down on the bolt to secure the tripod attach point to the round bar, there was still rotation of the binos about the bar as I made such simple adjustments to the binos as focus adjustments, etc. This renders the size and sturdiness of any tripod (necessary for binos of this size and magnification) as meaningless since the bino's mount is inherently flexible and "untightenable" due to its design.

I could not disagree more with another reviewer who says "I suggested that everyone who wanted a $500 pair of binoculars for $250 needed to go to Amazon and purchase one before the price went up". I paid $219 for these binos and that is about what they are worth *if* you are willing to tolerate substandard optical performance due to internal reflections and a tripod attach point that is not (and will not be) sturdy without substantial mechanical modification.

I am returning these binos to Amazon for a refund and will purchase a better pair from them soon and will consider it money well-spent.
