Amateur Astronomers Checklist Part 1

It's one thing to forget your bag of eyepieces or your hand controller in the basement when you've set up your telescope in your backyard. It's another to forget your bag of eyepieces or your hand controller when you've driven a hundred miles to a dark sky site on a pristine night of perfectly clear sky. If that happens, your evening is over before it begins, and your eager anticipation of a night of pleasant stargazing is replaced first by astonishment, then anger, then frustration, and finally, resignation. There'll be no stargazing for you tonight.

Most amateur astronomershave forgotten some important piece of gear back home. And it's no wonder. Even visual observers must often pack dozens of pieces of equipment large and small, from power cables and tiny Allen keys to massive counterweights and laptop computers. It's too much for most to remember, especially if you have more than one telescope or you alternate between visual observing and imaging.

That's why, in this article, we've put together a framework to help you set up your own ‘Astronomy Gear Checklist.' This one's aimed at visual observers, and it includes a list of commonly used bits and pieces, from your telescope's optical tube assembly (OTA) to your bottle of bug spray. No one needs all these items for every observing session. But you can use the ideas in the following list to assemble your own equipment checklist to match your telescope and personal situation. You might even create more than one checklist to match each of your telescopes and your various observing interests.
