Hi Guys,

Visited the inlaws in Ireland a couple of weeks ago, and managed to get a nights stargazing in from a lovely dark site, took a few snaps and here's one for your perusal, a few stars and a little of the milky way. Single frame of 240 seconds at 800 ISO, Canon 20D with 17-40mm f4'L' lens at 17mm f4 on a good old EQ5.

Hope you enjoy, comments most welcome.

Alan.

I was wondering how the 17-40mm f/4L does with astrophotography. Looks like it does really well. Do you have a larger image we can look at?

Yes the EQ5 was polar aligned and driven, the 17-40 seems to cope very well with astroimaging both on 1.6 and 1.3 crop bodies.

Here is a link (fingers crossed) to a larger image

A Lot of detail there for a 4 minute frame. Dark skies make a LOT of difference.
