Nebula Booster NB2

I was worried about light pollution ruining my astrophotos, but this filter cuts through it beautifully. The Hα and OIII lines come through crisp and clear even from my backyard.

I paired this filter with my astro-modified DSLR, and the dual Hα/OIII passbands really brought out the hydrogen regions in the Orion Nebula without overwhelming the blue-green. The contrast on the surrounding dust lanes is noticeably better than with my old broadband filter. It threaded onto my cam

My first test shot with this filter on my DSLR showed the nebula popping through the background stars way better than my old clip-in did, and the dual line-pass design really does pull both the red and teal details in one go. The threads were clean and it screwed in without any fiddly adapter issues
