NGC 5373 is listed as 15.3. I found another listing on the web of it listed as 15 photo, 14 visual. Are you sure 15.3 is correct?
Here's another 4407, SAG has it at 12.7, SEDS has this:m_b: 12.7 (mag) , m_v: 11.9 (mag) , SB: 13.0 (mag per square arcmin)
I observed 4407 the other night and I was not seeing 12.7 deep. I was barely getting to 12.1 or .2 w/averted only. 4407 was standing right out there.
