How does astrophotography differ from regular photo taking? For starters, you need a good refractor telescope with an excellent, special design camera. You will take a series of shots of differing exposure to catch the more or less luminous parts of objects, you will repeat it with different filters. All this while the sky moves above you and forces you to adjust the position of your equipment. You will interpose the images in a photo editing software and eventually produce a final photo.

What challenges await an astrophotographer? Light pollution is one. Jerry takes various steps to limit its impact. To block off neighborhood lights he built himself a small observatory in the backyard of his house. Ambient light - the light of New York City, Long Island villages, even the water, is a problem, as well. Jerry acquired various filters to block it off. In spite of all the precautions he still has to post-process his images to remove the noise from them - an arduous task that can take up to 20 hours per image.

Why go through all this trouble, you may ask? Beauty, serenity in spite of the dramatic events eons away, humility, curiosity, challenge. You can find it all in Jerry's spectacular photographs.

What is on Jerry's wish list? Bigger and better equipment, moving his observatory to a darker place allowing for short exposure, crisp images not marred by passing planes. Jerry would love to observe the skies in the Southern Hemisphere to see the famous Small and Large Magellanic Clouds, chaotic and less rhythmic than our own galaxy. In the meantime, he just loves to live by the iconic advice by Jack Horkheimer of the Star Gazer - he keeps looking up!
