UHC Filter comparison
I set up the spectroscope with a 600 lpm grating with a solar spectra to compare the "blocking" of some well known UHC filters......... I was surprised by the results.
The Lumincon OIII has a VERY similar responce to a Meade 4000 Narrowband filter
The Baader UHC-S is almost identical to the Meade 4000 Broadband filter.
I should be able to document the results next weekend and can now offer to "test" any other filters the group may have.
