[TenTec] O II Filters

[Larry DiGioia]

I am aware of the supposed attenuation on the narrower filters, and have 
tried testing this many times. I am unable to notice any attenuation 
except very occasionally with the 300... and I also have heard (here) 
that this attenuation is only a problem on Orions, not Orion II's.

In other words, I am quite happy leaving all enabled and auto-select on. 
(I should mention that I also seldom use wider than 500 or 600 Hz either.)
