Would the 10x50 model be suffice for Astronomy?

Absolutely! For starters, Bushnell is a highly respected optics company. More specifically, these binoculars have several features that are exactly what you look for in astronomical binoculars such as:1) 10x50 (and 7x50) are the two most popular sizes for star gazing. They provide sufficient magnification without being to "shaky" when handheld. 10 stands for the amount of magnification, and 50 is how many mm the objective lenses are across. 50mm is ideal for capturing light emitted by the cosmos in order to view them. Anything larger than 10x50 will become bulky and likely require the use of a tripod to maintain steadiness.2) Tripod adaptable: 10x50's can get heavy over an extended time, and the ability to place them onto a tripod is always a perk. 3) BAK-4 Prism provides the highest quality for visual sharpness. (BK-7 is of lesser quality).4) Porro style: optimal style over compact (roof) binoculars as the design requires less strict tolerances when manufacturing. They also provide a more stereoscopic (3D) image than compact binoculars. 5) Fully multicoated: The perfect combination for star gazing. From lesser to higher quality of lense coatings goes as follows: Fully Coated (one layer coating to outside facing lenses) --> Multi-coated (*at least* outside facing lenses are coated multiple times) --> Fully Multi-coated (all surfaces of lenses--inside and outside facing--have multiple layers of coating). The coatings are important because they limit the amount of light that is reflected away from the binoculars. The more light that enters the binoculars, the better the visual quality. 6! Waterproof/Fog-proof: especially useful with stargazing as the temperature changes at night cause the lenses to fog up. Finally, if you still need some convincing, these binoculars can be found on the astronomy retail giant Orion's website, and are located under the "Astronomy Binoculars" section of the website. Here is the direct link to the binoculars on their website: http://www.telescope.com/Binoculars/Astronomy-Binoculars/Bushnell-Legacy-10x50-Waterproof-Binoculars/pc/-1/c/5/sc/72/p/101469.uts?sortByColumnName=SortByPriceAscendingFor the price, and for someone just starting out in astronomy, these are nearly perfect for the price.

Are either the Bushnell Legacy WP 8x42, 10x50, or 10-22x50 binoculars tripod mountable?

The specifications on Bushnell's website clearly state that the zoom model is adaptable for tripods.http://bushnell.com/all-products/binoculars/legacy-wp/10-22x-50mm

Would these be good for sporting events?

In general I would say that the Bushnell Legacy WP 8x42 binoculars are good for just about anything. Not great, but very good. Very good for the current price of about $75 here at Amazon. To move up in all-around quality the Pentax 8x40 PCF WPII is currently selling for about $115. The Pentax are superior in every way but field of view in comparison to the Nikon 8x40 Action EX that are currently selling for about $150. If wide field of view is your major concern I would go with the Bushnell Legacy. If overall optical and build quality are most important then the Pentax might be worth the extra $40. To take it up another notch you might consider the roof prism style Carson 8x42 3D series with ED glass presently going for about $200 here at Amazon. Great all-around binocular for the price. For the money spent I don't think you can beat the Bushnell Legacy, the Pentax PCF WPII, or the Carson 3D.

Do these come with a case ?

yes they do. the 10x22x50 come with a flexible vinal padded case. with velcro to close, and Bushnell with gold letters letters on the flip over part. comes with adjustable strap about 1" in width.
