Title: Canon 600D ISO1600, 20 secs, Sigma 11mm, F3.5, cls

Nothing too exciting, but had Canon on tripod, last night. Not a lot of stars on view, would be better from dark site.

Nice shot Fay, did you have a LP filter on.  If I had done that from Bromley it would have been orange.

A very nice wide angle shot.  Unmistakably a Winter sky but so rarely seen nowadays!

It reminds me - I really must get myself a very wide angle lens.

Yes cls filter. really it was a focusing practice. It was nowhere near infinity, where I expected it to be may not be quite right yet.

Hmm....

Bit beyond my budget.

I was thinking more of something like this Samyang/Bower

The Bower lenses (the same lens comes under several different brand names) have always had a good reputation and are reasonably priced.
