Even the distant Uranus, Neptune and Pluto are within your reach.

I used to make my observations with my 200mm F/5 newtonian. I live in Brazil's biggest city (Sao Paulo - "Saint Paul") with a very heavy light pollution (and a "dirty" atmosphere). The newtonian was too big and heavy to be moved quickly to a small town inside and back to home. So, I sold the my newtonian OTA and bought a more portable Celestron C8 Starbright XLT OTA. I thought C8 would be better with moon and planets and but not so good with DSOs. I was wrong! The C8 has a very good resolution even with standard 1.25" eyepieces. It do a very good job with higher magnification and still remains illuminated. Star clusters (Omega Centauri, 47Tuc) could now be seen now bigger and more clear. "Nebulosities" like the Sombrero galaxy, Orion's nebula, Jupiter's Ghost are still well visible and clear in my big city. The astrophotography capability looses from a F/5 to an F/10 OTA, but you can reduce this disadvantage with a 6.3 focal reducer and field corrector. In overall, I think I did a good barter.

Just got the OTA the other day and luckily the sky was clear for First Light tonight. I was using another new toy I also ordered, the Explore Scientific 14mm 100 degree eyepiece. I can not even describe my joy with what I saw tonight. My older Celestron Ultima 20 to 30 years old? Was having issues so I replaced it and the new scope is tack on! Jupiter had cloud bands I could not see with my old scope. The Moons had substance not just pin points.I actually could see ALL six stars in the Trapezium in the Great Orion Nebula. I've only seen those six stars in a home built 18 " Truss Dobsonian one of our Club Members built. I used some other eyepieces and had great results. Was worth every penny I spent on it.
