Another experiment that sat on my drive for a while, I think it's about 10 hours of total exposure 4Ha + 6 through L-Enhance filter on stock Canon camera. I've learned that I'd probably need more time for individual exposure with Ha. NGC 7822 aka Teddy Bear Nebula. Shot with Canon 3ti, F/2.8 135mm, L-Enhance and Ha filters. #astropic
