Exactly what I wanted!

This was perfect because I have a mount and tripod that I already enjoy using. It was very easy to mount due to the vixen dovetail. I've gotten awesome views of Jupiter and Saturn and I've truly enjoyed this scope so far

High quality viewing at an excellent price

I purchased this telescope as an upgrade from my first cheap one. Setup was easy and fit and finish on the optical tube is impressive. The optics are great and when I compared to similar scopes by other brands, this one was the best value for the price

Reduced aberrations & excellent views

This is my first long FL refractor telescope and I must say I'm more of a fan than I'd even anticipated. Larger apertures tend to have more aberrations but this scope is a perfect balance and the reduced chromatic aberration is very noticeable. Glad that I was able to purchase the telescope alone without the tripod as I already have a good setup and the vixen style dovetail made it easy to mount. Arrived exactly as I'd hoped, shipped quickly, and TelescopeTek was communicative through the process.
