Ok, I'm an old guy who's memory is not what it used to be. I can't seem to remember to turn off the red dot finder on my NexStar, so I'm constantly buying batteries for it (CR2032 if you're interested - I did THAT from memory!!) . So, what's the best place to put a little note to remind me. On the inside of the objective lens cover? Put there, the finder will remain on until I'm done observing but the note won't be in a "public" place. Or on the back of the scope, where it will remind me to turn it off each time I'm done using it but everybody who sees the scope will know I can't remember things? Somewhere else?
