I'm not sure what you're wanting to do. For most astronomical objects, you would want to take a number of images and then stack them. You certainly won't get any "automatic exposure" device for anything like a galaxy, or a nebula, they are just too small and too faint. You will be talking exposures in the minutes, or even in the hours in extreme cases.

Try the following pages from the Astronomy magazine website, if you click on most of the images, the photographers submitting them provide the tech spec as to how they produced that image so have a look at something which corresponds with whatever you would like to image, and start from there. Though there are many ways to skin a cat!

Does anyone know the name of this plant? I'm trying to re-name and organise my photos, but I have no idea what it's called;

A couple of years ago, I took this

Was there again today with my little one on her bike so thought I'd recreate it

This photo from an Under-11s soccer match was shot with my Nikon D600 and Nikon 80-200 f./2.8 using the 3D Auto-focus mode.

Details: Raw; Manual mode (1/500s, f.6.7); Auto-ISO (180); cropped to A4 aspect ration in Lightroom.

The picture shows my grandson (in blue with the ball) reacting to the referee's whistle having just been caught offside.

You can see that the focus is not where I would have wanted it. Straightforward user-error. Wrong choice of AF mode.

But the body language of my grandson's team-mate ensures it's a keeper!

I agree. Thanks for the advice.

Mrs LBWR works for the University of Birmingham and the educational discount brought the price down to £60.

Ha! I'm loving that little lad as well!

What the 'eck. Self portrait. Taken yesterday. Canon 40D; Sigma macro. All the household lights I could muster, plus a small lamp pointing up from waist height. No airbrushing; no make-up except a little brow pencil (advancing decrepitude means they're faint, otherwise).

What does the badge say?
