  • Hello, I recently purchased yesterday the $240 AO Riechert 150 model and am now curious to know if this would be a better scope though it has din objectives vs. the infinity objectives of the AO Riechert. Am I able to place darkfield filter in the AO Riechert as I am with this scope? Thank you, Jeff
