Hi Stevo
Don't worry too much about getting transparency and seeing "right", it's a personal estimate and like Iceman said, it can be tricky. I use a 0 to 5 scale with 5 being excellent.Consistency is the important thing.
Many years ago, when i started to record observations I used to agonise over the seeing and transparency conditions which resulted in wasting observing time. So my advice is to just give it a shot without worrying about being "right"; you'll soon get used to it.
Checking the faintest stars you can see with the naked eye and the amount of scintillation in stars can guide you. As you become experienced you will come to notice that some nights are less transparent than others and rarely do you get a night where seeing and transparency are both good to excellent.
Enjoy your observing, trust your observations and don't worry about getting seeing and transparency "right".
Cheers and happy observing
Malcolm
