Thanks for the replies,
Glen, I split myself between country Victoria and on occasions, the northern suburbs of Melbourne. 80/20. So light pollution is not a big problem. at home light pollution (street lights etc.) are not a problem.
I have noticed that the screens on these tablets cannot be turned completely off - i.e. with the brightness at minimum there is still a screen glow. Anyway each to his own, if you have a use and end they enhance your observing good on ya
acropolite, a good idea with the red gell there. Is it cellophane or the red gell that lighting technicians use for colouring lights?
AG Hybrid, I will look for an iphone app later. Hopefully there is an equivalent one to the Screen filter.
Ron, I guess you are similar to myself. Honestly have no use for electronic devices at the eyepiece. My last star party was over twenty years ago, so back then these sort of devices didn't exist!
