Long exposure dishes (53 mins)

53 minutes in a single exposure? The Canon 6D eats that up.

The first image is a single 53 minute exposure captured at Narrabri. The dishes obviously moved during the exposure – at first I wished they hadn’t, but the more I look at it, the more I don’t mind it Gives it a sense of movement, along with the star trails which show the movement/rotation of the Earth!

Captured at ISO100, f/11, 24mm with the Canon 6D and 24-70mm lens, 53 minutes single exposure.

To show what the Canon 6D is like with long exposures, here’s a 100% crop, completely unprocessed. No noise reduction applied, just straight conversion from RAW to jpeg and cropped. No ICNR either.

The image was taken under moonlight so the sky is brighter than I would’ve liked, but it shows how great the 6D is in low light with long exposures, and how little noise there is!

The second is a shot similar to the top one, taken within a few minutes actually, but is just 18 minutes instead of 53 minutes of single exposure.

The shorter 18 min exposure meant some of the settings were changed to get the same ‘light’. The second one was at ISO200, f/9.


I also took one with the one of the Dishes pointing towards the LMC.

Thanks for looking!
