First Time Viewing the Night Sky
By this time you are itching to get going and don’t let anything stop you, but just a couple
more things for consideration. Have you read the menu tree of the AudioStar Handset? If
you haven’t made a copy of that menu tree you better have the instruction manual readily
available, you’re going to need it. There is options on top of options available on the
AudioStar Handset that you as the telescope operator have to choose from and one of the
first things to do is provide the handset with the time, date and zip code. This will be
important because AudioStar needs this information to tell you what is available for
viewing. It can be rather frustrating to try and figure all this stuff out, in the dark when
you really don’t have a plan.
Start off with the MOON. It’s big, it’s easy to find and most of the time it is so bright a
lunar filter should be screwed into to bottom of the eye piece to knock the brightness level
down a few notches. There plenty to see on the moon and the best time to view the
moon is when it isn’t completely full. There is a lot of detail on the “Terminator Line”
between light & dark and many astronomers favor this. Also, there is this thing called
“Beginner’s Luck” where you might see something on the moon’s surface that many
astronomers never see. A couple of those special things are the “Lunar X & the Lunar V.”
The is a couple of major named craters on the moon’s surface that when the light strikes
them at a certain angle a lighted “X” and a “V” are clearly visible. You never know,
sometimes it’s better to be lucky than good.
