you've got some really fine captures here... the cormorant, a tough bird to shoot (and get good detail on) is excellent....the starling (what a pest they are) nicely defined, and the robin in mid-note.... also very nice.... thanks for sharing, dave m
After seeing your shots I was about to reply pretty much exactly what Dave said...so now I have to look unoriginal and repeat some of it. I have Comorants swimming by my back door 7 months out of the year and have yet to get a shot with that kind of detail in the feathers. Don't know what you did but you did it right. As far as the Starling, you made a dull bird look very interesting. Wonder what you could do with a Peacock?
I used to fire 155mm artillery that was smaller than that monster. Since its not listed in your sig, time to bring it out of the closet and introduce it to us.
I sold it 1 month ago, but i'm planning to get something similar.
It was a SkyWatcher 600mm Evostar 80mm ED Astro scope. Sometimes i whacked on a Teleconverter, but mostly shot @ 600mm
You just cant get the reach in a DSLR lens for the money these babies cost. The downside is fixed aperture, manual focus, no IS, basically....nothing. Its just a tube with 2 glass elements stuffed in one end, and a focuser at the other.
