the moon light robs us of a lot of good seeing, hope it buggers of before the weather comes back again. for that big cluster its not an equalateral triangle the sides pointing at it are about 2 times the lenght of the base. hope that helps. with my 12"f5 dob the view of it is amazing with a 30mm ep, almost fills the whole field. with so much light out i recon the keyhole nebula in eta is the go over the other side id say omega and the eagle nebula i think will be visable with your scope. stellarium is a great free download and will lead you in the right direction also. i would still be blind without it.
