Very good image. A significant upgrade over my 10x50.
on November 25, 2013
Thick solid metal tripod adapter.
18mm wide eyepiece, vs 16mm on my Celestron 10x50 and 13mm on my Tasco 7x35
1.5 inch wide neck strap with leather backing
Thick, padded carrying pouch, without a strap
My reflection in the Nikon lenses (Objective and eyepiece) are dimmer than in my Celestron 10x50's by at least half, which is good for the Nikons.
Sharp images with easy smooth focus. Not much turning required to focus.
Near focus of 15 feet not 28 listed, but I am a bit near sighted but don't use glasses
Light and easily hand holdable by me, but I've had lots of practice and am young. I can hold it steady with one hand.
Measured exit pupil at thinnest point, and it is exactly 3.1mm, vs 4.3mm on Celestron 10x50
Pressing my eye sockets against the eyepieces does not move the focus
I can see veins in distant tree leaves that my 10x50 only shows the general leaf shape of
The objective covers stay on easily and can clip onto the neck strap.
As I look around my dark house inside, lit only by one computer screen, the view through the Nikons is no darker than with eyes.
The smooth sides of the eye cups makes it easy to tape paper light shields on them to block side glare. It made the viewing that much more enjoyable.
Careful measurement confirmed that the apparent field of view is indeed 61 degrees, a degree wider than my 10x50 wide angle, and that the magnification is indeed about 16x.
During the day, I must look straight forward. I can't move my eye to look around the field of view like I can with my 10x50, because the exit pupil is smaller and gets blacked out. This is not a problem at night. At 5pm, with my pupil a bit larger, this is no longer an issue. I get better use during the day if I'm very careful to measure my interpupilary distance and match the eyepiece distance to it exactly.
The eyepiece covers are too big and fall off the eyepieces. But they do clip on the neck strap so they don't have to fall on the ground. With some tape, I can make my own covers that double as side light shields.
The carry pouch, although nicely padded, is small, and you have to really stuff the binoculars in there to barely close it.
The Andromeda galaxy and M33 are easier to see with the 16x50 than with 10x50. I did not see a dimmer view with the smaller exit pupil. In fact, the Nikons seem a bit brighter, even when looking at houses without any porch lights nearby. The Pleiades look better and show more stars in the 16x50. When looking at Venus, near sunset, I noticed some faint stars with the 16x50 that I could not see with the 10x50. Orion's belt also had a denser star field in the 16x50 than in my Celestron 10x50, though not by a large amount. Venus looked larger, but I still could not see its phase. Jupiter looked larger and rounder in the 16x50, and the moons were a bit easier to see but still small. I could not see stripes on Jupiter. The moon looked a bit better too, though not spectacular. I did not see any extra details at 16x that I could not see at 10x; however, I did not have to look as hard to see them. Any detail obvious at 16x could be verified at 10x. I was getting tired from being up late, and shake was more noticeable in the 16x than the 10x.
I can locate M82 and M81 in my 16x50, but not in my 10x50. M51 and M101 are much easier to locate too.
During the day time, the 16x50 expands every detail I could be curious about with my naked eyes. It makes me feel like I'm over on that distance hill, walking through that tall grass. The 10x50 is more for seeing the full picture.
16x is as high as I can go and still have good depth of focus on terrestrial objects at different distances. At 25x, I have to refocus for each distance. Also, 16x is as large as I can go and still figure out where I am in the sky just by panning around. At 25x, I can just point and look but not know where I'm truly at unless I recognize and object of known location.
I recommend owning a Nikon 7x35 and a Nikon 16x50 for both big picture views and detailed inspection. Get a telescope if you want more power.
