On getting the new scope and First Light. The general rule is 50 x aperture for how much magnification you can use. But that's only on the best of nights and mostly for the Moon and Planets. I say the rule is, when you can't focus anymore, it's enough magnification. Each night is different depending on the sky conditions. Most of your deep sky viewing will be done at low magnification. 50 to 100 x is fine for most deep sky objects. Plus they are easier to find. It's not about magnification, it's about gathering light and your 8" will do a good job. Good Luck. Keep us posted.
That's it;
