Preparing For An Observing Session - Omegon EQ-1 Mode D'emploi

7. Preparing for an observing session

It is a good idea to prepare for your observing during the day. Lay out all the accessories and telescope parts
you intend to use for the forthcoming observing night. Remember that it could be very cold, so warm clothing
is advisable. It is very important to wear snow pants and moon boots, or equivalent, in winter.
Think about the objects which you will want to observe during the session. It is a good idea to consult a
planisphere and star atlas for this. These allow you to see exactly which constellations and objects will be
available on the night in question. Some observers keep an observing book, where they record all the objects
they have seen.
Take the telescope outside about a half an hour before you want to begin observing with it. This is because it
must be allowed to cool down sufficiently before it will be able show you objects clearly. Your eyes will become
completely dark adapted in about 30-45 minutes of darkness. Avoid looking at any sources of white light as
this will mean you immediately lose your dark adaption. It is highly advisable to use a red astronomy flashlight,
which will allow your pupils to remain fully dilated but still let you read a star map and find your way around
during observing.
