Choice of no regret

Now I'm using it and this petzval scope makes perfect image. Stars are almost flat everywhere in image. This scope is ready-to-image, there's no need to add other reducer or flattener to this scope. So I took my first image at the day when this scope is delivered to my home. And I need to get some paper about customs clearance. OPT sent me the paper as soon as possible. I really appreciate about OPT's excellence service.
