Brent, soon as you get your 10" going, plant it on NGC104 (47 Tucanae)
It is a treat to behold and it will blow your socks off! Honest! In my opinion, this one is way better than Omega Centauri as it's not so dense and the stars were easily resolved and bright. Looking at this glob likened my reaction to seeing Saturn for the first time. Have a go for now anyway with your 4.5" in the mean time and see what you can see, if you haven't done so already.
Patrick is spot on. When I first came across Carina and Sagittarius, I used my binos on them first - it was much like opening a box of chocolates when you look thru binos in these constellations - you just don't know which one to start on first
.
When I first got my scope and pointed it at the Orion nebula, my daughter told me she could see a green tinge and I told her she had a great imagination, as all hubby and I could see was grey. I later found out that it does indeed have this colour tinge to it, and that older eyes have trouble picking up the colour. So have a go - you may be lucky.
