Optical Coatings on Telescopes

Summary: This is why some telescopes cost substantially more than others.

For most people, seeing the planets will require little more than a telescope and a clear evening. However, serious star gazers will want to consider an upgrade to telescopes that feature lenses treated by optical coating systems. These lenses have several advantages over the standard store-bought varieties, but they aren’t always easy for the newcomer to recognize. If you’re wondering why some telescopes are vastly different in price, this may help you understand.

Coating Types

Before we dive into coating types, we need to first make note of the method in which the lens is coated. Cheaper methods, like the dip and bake, may lower the cost to you but the quality suffers greatly. The coatings don’t last as long as an ebeam coating would. Within a year or two you’ll literally wipe away the coating.

Aluminum and titanium oxide, as well as magnesium fluoride, represent the most common substance used. High quality lenses are “fully coated,” which means that the coating has been applied to both sides. This is different from “multi-coated” lenses, which may also carry a high price tag. The multi-coat name comes from the multiple layers of chemicals applied to the lens in order to alter properties like light transmission.

Buying Your Telescope

In addition to any coatings applied to the lens of the telescope, you might want some additional upgrades. A tripod mounted telescope, for instance, are easy to set up and provide stability. You can also purchase telescopes with recording capabilities, so you can capture video footage for time lapse editing later.

Keep Your Animals Safe with Electric Fences

Written by Farm Supply Store

Do you own a number of animals? Perhaps you’re a breeder of some sort or a farmer who has livestock. Whatever the case, that many large animals need to be protected. Often, they’re their own worst enemy. If you don’t keep them safe from themselves, they’ll end up getting hurt all on their own or run away altogether. However, you also need to keep them safe from outside threats like coyotes and other wild animals.

1That’s why so many people insist on having an electric fence surrounding their property. Many have separate areas for different types of animals that are built in electric fence wire and thus able to keep every creature where it belongs.

To those who think it may be inhumane, you can decide how much electricity each fence gives off with a shock. The good news is that it doesn’t take much to tell animals they need to stay put. Usually, it also only takes a few contacts before your livestock learns it’s not worth trying again.

Electric fences are also a good way to keep outside animals away. Just like your livestock, they’ll soon learn that trying to get after your cows, horses, etc. isn’t worth feeling voltage go through their bodies every time they try.

Approvals to Look For

If you live in a high-wind area, you may want to look for storm doors that are rated for hurricane approval. For the highest levels of approval doors must be tested and rated using a variety of tests, including impact and cyclic tests, air infiltration tests, uniform static air resistance tests, large missile tests, and water resistance tests. Make sure your door has a “sweep”, a strip along the bottom of the door designed to keep out bugs, air, and moisture. Door closers may be included or added to pull doors shut on their own again if blown open.

 

Maintenance Tips

Regular maintenance ensures storm doors will continue to provide high quality protection against rain, wind, and debris. Check for dents, scratches, torn material, and debris in hinges and between panels. Check the closer and latches to ensure they are securely attached to both the door and the door jamb. Regularly oil and open and close storm doors to check on their proper function.

 

Additional Solutions

To enhance home security during hurricanes and other inclement weather, consider purchasing storm shutters made of plywood, fabric panels, or corrugated steel or aluminum, depending on your needs. There are a variety of pros and cons; however, so long as they are properly installed almost all solutions will improve overall house safety.
