IDAS HEUIB-II Filter

I have realized HEUIB-II filter should be perfect for nighttime landscape shots with modified DSLRs. These were taken by Scott Denning.  The filter isolates Ha emission from the background while maintaining the overall color balance correctly, including the terrestrial section.

Paul Chasse is enjoying with his recent system. Nice color!!
