View the Eclipse Safely

Our eclipse program is full, and the waiting list is full as well. We have no more eclipse glasses available (beyond what we have set aside for the program participants).

First, a safety rule: Never look directly at the sun without proper eye protection.  People have gone permanently blind in the past thinking that they could. Long Island is NOT in the path of totality so there will never be a moment when you can look at the sun without proper protection.

According to NASA:

Many people will obtain eclipse viewing glasses. To date three manufacturers have certified that their eclipse glasses and hand-held solar viewers meet the ISO 12312-2 international standard for such products: Rainbow Symphony, American Paper Optics, and Thousand Oaks Optical. These companies may be found online and the glasses ordered, but you really need to order your glasses many months in advance because of the anticipated huge audience that could number in the hundreds of millions. Also, NASA is partnering with GOOGLE and making arrangements to distribute viewing glasses to many institutions and groups along the path of totality. If you are a photographer or amateur astronomer, you will want professional-grade solar filters to cover your binoculars, telescope or camera. Companies like Thousand Oaks Optical and others you can find by using the keyword ‘Solar filters’ have these filters for sale, but again due to the large number of likely customers along the path of totality, you need to order your filter many months in advance. Do not wait until June, 2017 to get your filter. You will also need some time to learn how to use the filter with your optical system, and if you are photographing the eclipse, take lots of test shots to get the right solar disk size and sharpness.

With the eclipse days away, if you search online you will find that proper protection meeting the ISO 12312-2 standard is no longer available. So, what can you do? Below is a link instructions on how to make your very own eclipse viewer using items you probably have around the house.
