What's the verdict on the various deep sky general purpose nebular filters? Essential, reduce light by too much? The offerings I'm looking at are:
* Meade Nebular Broadband 911B
* Orion Sky Glow 05658
* TeleVue NebuStar BFH-200
* Thousand Oaks LP-1
* Lumicon Deep Sky LF3020
going roughly from cheapest to most expensive. What's your experience been with these?
