Yes Scott, it is addictive. Yes the mozzies/sandflies/etc are a pain. Being covered in repellant and wearing long sleeves and trousers on hot nights is par for the course.

Anyway, my question is:
The bright side of the moon looking with the naked eye up at the sky was on the left, when looking through the scope, the bright side was on the top. Should the bright side be on the right? I've got a reflector scope.
The moon kept disappearing toward the top of the scope eyepiece but was moving south west in the sky.
Can someone please help me understand this?

Up/down and left/right are a function of the number of focal planes, lenses and mirrors in the light path.
Here is one brief explanation with images. Which direction the image moves in the FOV depends on the inversions, the type of mount, and if the mount is tracking on how accurate the tracking is.
