Quote: I said that these lab experiments were set up under conditions which may not accurately replicate those in the actual visual observations of bright nebulae.
It is the last defense line to sustain that your percetion are more reliable. You no longer question the paper or the method, but "it does not exactly apply to my case". (The same is for the filter: "it was a OIII not a UHC - mine has a red leakage that starts a 6200 angstom, yours at 6100. the leakage is similar... but I bet you will claim not enough).
