Peeb, that just shows that its not the camera that takes the picture, it the photographer that takes the photo, because I have the same camera and my photos came out horrible. My longest lens right now is the 50mm though.
Very kind of you to say that- this is my second lunar eclipse attempt, so I simply tried to correct some of the issues I had in the first go-around! I started with the location. I have an app that measures light pollution, and I found a nice dark spot only 6 miles from my house, so that was a good start. (Light pollution wasn't going to significantly impact the moon, but it would mask the stars a bit...).
Here was the rig: Nikon D7200 with 200-500mm zoom, set at 200mm . I exposed this image at 1/2 second, wide open (f/5.6) at ISO 4000.
Even tho I shot all nite at 500mm, I intentionally backed off to 200mm for this shot for two reasons: (1) I wanted to capture some stars, and (2) the longer your lens is, the shorter your exposure must be. In other words, a 500mm shot will begin to motion blur from movement of the moon/stars much more quickly than a 200mm shot.
I have an awesome tripod that is SUPER stable (and heavy) and I use a ball head that allows you to reorient the camera sideways to make kind of a poor-man's gimbal. I used the self timer to avoid jostling the camera. I also turned off noise reduction and vibration reduction since the camera was already stabilized.
I experimented quite a bit with various ISO settings and shutter speeds and shot as slow as 2 seconds, but found that 1/2 second was a good compromise. I could get out some grain by going slower, but then movement blur became a concern.
If ANY of that helped, there ya go. If I made a few bad choices in there- anybody that can give me a pointer would be appreciated. I'm already looking forward to the next one!
EDIT: just gave your 50mm lens limitation some more thought. This is too short to be telephoto, but you COULD do a time lapse series where you depict the progress of the eclipse with an interesting foreground. I had another camera with me last night and tried to do this but it was a fail due to a focus miss (even tho I used painter's tape to stabilize the manual focus ring) AND lack of a really nice foreground AND frozen intervalometer.
EDIT 2: ALSO, forgot to mention that I was doing a 'kinda time lapse" by being sure to shoot at least every 10 minutes until totality. Due to the cold, I had hand-warmers taped to the lens to prevent frost from accumulating on the glass!
EDIT 3: BTW, the 'mission timer' started at 7:19pm when I left the house to set up, and ended when I walked back into the house at 1:13am- so it was a nice long time to be out in the elements!
