The main reasons for this are that the moderate 7x magnification makes it much easier to keep the image steady as your small hand movements are not magnified as much as on higher powered instruments.
On a boat that will often be moving this is important and for astronomy, it makes it easier to obtain a sharp image of the moon, stars or planets without the need of a tripod.
The lower 7x magnification also generally produces a wider field of view which enables you to take in more of the action without having to move the binoculars about which is great for stargazing. A wide view also makes it easier to quickly lock onto your subject, which for something like small and fast moving birds is important.
Then there are the larger 50mm objective lenses that capture more light than smaller ones which is important, but when you then combine them with the 7x magnification it creates a really large 7.1mm exit pupil. This is really important when you have very low light levels like you get during early morning or late afternoon birding or indeed for astronomy at night as these shafts of light exiting the eyepiece are large to ensure your eyes receive more than enough light even when your pupils are at maximum dilation.
A real highlight on these 7x50 Solaris binoculars, especially for eyeglass wearers is the massive 30mm of eye relief which is certainly more than enough to ensure that you can use the binocular and achieve the full image whilst wearing your glasses.
At 4 meters, the minimum focusing distance on these Yukon binoculars is typically relatively long for this type of instrument and thus not an ideal choice for very close observation uses.
