Seems every post I make now is with a different set of gear. This switches it up again. I’ve always been intrigued by the prospect of shooting quality narrowband through my big 6” achromatic refractor telescope.
This image proved to me that it can absolutely be a reality. They don’t focus all light to the same point but with the proper filtration, you can sidestep this limitation. In this way you can get pretty decent quality at “more reasonable” prices. Just my style.
Too good to be true?
Proof’s in the puddin’
I framed up the Cave Nebula here as my test shot.
How I arrived at this bicolor mix? I haven’t a clue 😆
