henomenal value
I recently upgraded my entire astrophotography setup. I went big on the mount and decided to go for a mid-range option on the scope. I am incredibly happy with this scope. It's very easy to use and the optics are incredible. The attached shots of the moon were from my first night out with this scope.
Shots of stars show great performance all the way to the edge. I've recently seen a few videos on YouTube with reviewers comparing this scope to ones costing 2-3x and there is barely any difference in the final images (usually limited to minor imperfections around the edge). I also have a higher-end triplet, and I confirm these findings.
Unfortunately, it's been cloudy almost every weekend since I got this, but I look forward to testing more with DSOs.
This is a shockingly good value. Pull the trigger! You won't be disappointed.
