It was the first light tonight with my GT70-90's. The seeing was good but the transparency was not. Jupiter was really nice with the 20x eyepieces, with the 25x I could see four bands. The four moons I saw looked crisp and pinpoints of light. The Moon was also very nice in both sets of eyepieces. The CA was there but not nearly as much as I thought there would be. The double cluster was, well, STUNNING! Sadly, M81 and M82 where not visible due to conditions. Keep up the good work.

I received my GT70-90 this past weekend and have had a chance twice to use them from my balcony at home. I'm impressed with the build quality. No cheap plastics here. [...] I'll be using these binos to start/complete my Astronomical League Deep Sky bino certificate. I've finished the A.L. Messier Bino certificate already. Also as you said, a red dot finder isn't really necessary, just sight along the handle. I think I'll have these a long time.
