I thought I should start with the easiest DSO in the night sky, the Orion Nebula. I started at 600mm and initially was trying at 10 to 20 seconds and obviously had long star trails that I thought was due to my weak camera stand. I could see the color in the pics with the star trails so I decided to put the camera on the ground and prop it up with whatever I could find in the backyard, and I still got the trails. That's when I finally realized my mistake and went down to 1 second and got a much better image, but with the stars still elongated. Then I finally tried the 0.6 seconds and that gave me almost round stars. I didn't want to up my ISO to 6400 so stayed at 0.6 seconds. I took the image in raw and disabled the in-camera noise reduction. The only edits in LightRoom were exposure, highlights, blacks, clarity and noise reduction. When manually focusing in the camera (live view zoomed in), I was surprised that I could clearly see the 4 stars in the trapezium.
So at 0.6 seconds exposure, I was pleasantly surprised to see how much color and detail was visible in the Nebula. This is my first try at a DSO. I've tried the Milky Way with the Rokinon 14mm a couple of times, the Moon and even the Sun, but never tried a DSO before. Next I'm thinking of putting the camera and this lens on my old Sirius mount (non-GoTo but with tracking drive) to see what i can get. Does anyone know if that will be good enough, or would there be a lot of shake because of the drive motors?
Question on the color - Shouldn't the green be more muted and the red more pronounced? Is it because of the lens or the un-modded camera?
