GC 7822 – The Cosmic Question Mark❓🤔
This is my first true attempt at this nebula and I like how it turned out. Also my first time really working with the Samyang 135mm f/2 lens. Shot this at f/2.8 and noticed I had a lot of distortion in the corners of a couple shots. Thankfully BlurXterminator was able to correct for this but I’ll have to figure out how to combat the tilt to remove it completely.
