Get some good water proof star charts. I like the Star Atlas and the Pocket Sky Atlas. You may want to draw in the constellation lines in the Sky Atlas (it’s a good rainy day activity!)
Use a dim red flashlight to preserve your night vision
Learn 3 or 4 Bright stars in different area of the sky for each season
Get familiar with how your scope flips images, useful when comparing to star charts
Get a Binocular that matches or is close to the specs of your finder scope. This will help as you will know that they have the same views and magnification so you will know what to expect
Get a comfy stool or observing chair!
A back brace may help too
Use an eye patch, you will look ridiculous but it will be dark so who cares, and you will save yourself from the strain from squinting all night.
