Hi Guys/Girls,

Can I ask how you guys edit your space/night shots. I finally managed to get a photo of our milky way last night despite many odds like crap rubbish weather and too much cloud. I took this shot on my Canon at 14mm which is a single image at 25sec on 8000ISO.... What is the best way round? Longer shutter with lower ISO or vice versa??

Anyway I am so pleased with this photo. For me its the first time I feel I got a decent shot... Can you guys please leave me some feeback and any tips on how you guys would edit? Is it possible to pull any colour out of the image? I used photoshop CS6 and the photo original is in RAW format.

Heya,

I don't find high ISO to be a problem with wide field astro. Whatever it takes to get enough data to work with. You're in a good spot.

For editing, this is where layer masks come into play, dodge & burn and unsharpen masks. Those are pretty much defaults. You can make a new mask, and brush in your edges, like saturation only in the area of the core. Also in a mask you can do selective burning. And when done do a little unsharpen mask to bring out more dust trails. Also a mask for a color filter to make it more blue or whatever color you desire to help mange noise pollution a bit. Also look up "asta la vista green" for photoshop, very useful for some light pollution.

Very best,

Simon,
20 seconds at around ISO 3200 is a good starting point. Using the 500 rule and the 14 mm lens you should be able to keep you shutter open for 35 seconds before you start to get star trails. (500/14mm = 35 sec) 500/ focal lenth= time. The longer time will allow you to drop your ISO (less noise) and still collect alot of stars.
