thanks for the advise i know nothing of cameras - i was suprised when i found out that the screens were removable- as i said i want to try a little widefield to get a feel for this astrophoto stuff- i constucted a hartman mask for the AR5 and it seems to work quite well=picked up the t-adapter and rings and will eventually give it a go- but for now just want to try some simple stuff thru the lens 50mm and 135mm until i get the hang of it-clear skies rocco WB9QPU
