southern milky way

[Somnium (Aidan)]

i shot this the other night and I am pretty happy with my first attempt at a wide field shot. i was using the stock lens from my camera at 18mm which showed up some serious Chromatic Aberration, perhaps stacking multiple short subs instead of 1 long sub would solve the issue.

Modded canon 600D
1 sub, 240 seconds at iso 400
Neq6 pro mount (a little overkill)
processed in photoshop

Thanks, i feel the colours are a little unnatural but every time fiddle with it i make it worse

nice one Aidan,

what was the f stop at? if you step it down it will help out with image quality. obviously there is a trade off with wide open aperture to get a signal when the camera is on a tripod (avoiding trailing) and not tracking. as you are tracking you can step it down with less of a worry and add more exposure time.

still -its a great pic especially from a single sub!

thanks

i used f2.8 which is the lowest my lens goes. i will have a play around with a few things to see if i can do better next time. lots to learn in nightscape imaging, but this shot was an afterthought when i saw how beautiful the milky way was at 3:00 am.

what really surprised me is that even though i was shooting at 2.8 and i usually shoot at 4 with my scope, it was extremely difficult to find a star in the live view to improve my focus.

At 18mm even inherently bright stars are tiny and not very bright. I have a zoom that remains focused well if I zoom up a little to around 28mm, so I use Live View at 28 and then zoom back to 18. You could try it with your lens.
