Although it was too windy to do prime focus work, took some piggyback shots of the glorious Southern Milky Way.

Location was Terrick Terrick National Park 220kms NNW of Melbourne. A fire in the area the day before shows up as some light coloured haze on the horizon.

All shots taken with a Canon 400D, Sigma 17-70mm DCMacro lens and up to 5 minutes exposure.

The compression for Web does not do the images real justice, really happy with the lens especially when steped up to a high f ratio.

Hi JohnK,
Fantastic shots, great colour and detail, I gather the 400D is unmodded ?.

cheers......Jim

Lovely shots John, I took some similar ones with my 350D + 17-70 at SPSP, but the transparency was ordinary. They're still on the camera but i'll get to them this week I hope.

What f/stop did you use?

Thanks guys.

Jim - yes, the camera is unmodded

Mike - stopped up to f3.5 & f4 at ISO800

Stunning images!

Do you think you could put them on imageshack for us all to see in high quality?

Try this one from my Flick page:

6 mins at ISO800 at f/3.5.

One of my favourite shots of the night showing some nice star colours and the Emu very nicely.

Beautiful shot! Thanks for uploading the high res version. Really says more than the web optimized one for this sites upload.

Great shots John, that Sigma 17-70mm lens sure works well.

Sometimes I think sigma makes much better optics than the Nikon Or Canon main brands, but doesn't include the "features" or waterproofing as the Canon "L" series lenses.

I love my Sigma 24-70 F2.8 and I would never spend $1400 for the Nikon version. I paid I think $350 for the Sigma.

Hi John,

Very nice shots!!! :)

Im also trying to get some nice shots of the milky way using my 400d camera - this is my first time in astrophotography.

Was wondering did you mount this camera on some tracking machine? I mount mine a tripod and getting some star trails at 6 minutes at iso800...

all the best.

Hi John, lovely set of images.....:thumbsup:
Really like the non CA on the stars, shows this is a very capable lens for wide field astro shots.

Thanks for sharing
Cheers

Thanks again for the comments guys.




Yep, for these shots the 400D rode on top of my 12.5" reflector, so you will need a tracking platform, however I have been suprised by the amount of stars that can be captured at ISO1600 in just 45 seconds. Perhaps you can try 5 to 10 stacks of 45 second shots and stack these in Registax or deep sky stacker?
