Haven’t had much time to used it because of the weather but you can tell is a quality instrument.... so far so good

Great telescope!

It wasn't too long ago that an air spaced doublet would be a lot more expensive.  There were no detectable flaws in the finish.  I have not taken it outside under a clear night yet but looking out through a window to align the finder scope I didn't see much chromatic aberration.  I already own two long focal length scopes so this relatively wild field scope will be a welcome addition.

The scope arrived today and I am well pleased.  .

Excellent achomatic refractor, good all around size for portability and visual observation especially when paired with a twilight 1 mount.

I'm a little disappointed with the finish quality of this telescope. The black piece that goes around the end of the dew shield looks like it had a bad glue job by whoever put it on.  The finish of the painted tube is a little bumpy here and there where it clearly should be smooth like they had gotten a little dirt on the outside of the scope while painting it.  Things like this make me question the quality of the rest of the scope.  I've used it a few times now.  The dove tail is painted so it will get marked up when it's put on the mount. The focuser feels smooth and does not go out of focus easily. There is a significant amount of CA on Jupiter, however the moon looks good. All in all, It's not bad for the price. Would I recommend it? Meh.  Probably not. I'd probably tell someone to spend another $300 and get something you'll be happier with.
