That lens does wonders at slow shutter speeds but I find that it is typically sharper above 1/160 and 1/250 if you can manage it. With the moon it is hard to get those shutter speeds unless its full. So far I have had better results with hand holding vs. my flimsy tripod. It is also very easy to over expose the bright areas of the moon and I find it works better if you are about 1/3 to 1/2 a stop under what seems right. Vandana mentioned manual mode... I agree.
Thanks V, I did use some noise reduction but it seemed if I sharpened it I had to counteract it so it was basically a no win situation.
If you are asking about the lens it is a 300mm f4 I purchased from Thusie.
I'll try your settings next time the moon is visible and see if that helps me.
I think you've done well, Gail - the outer part looks a bit smooth - is there some noise reduction used ? I typically shoot the moon at ISO 100- 200, f8-11 or so, and speed comes usually to 1/125 or so. manual mode - can't use aperture 'cause the camera takes in all the darkness around..but the moon is well-lit and exposes as a 'sunny day' Noise reduction again is very difficult with the moon, 'cause those NS modes take the darkness around and do too aggressive NS.this is at 300mm or some 1398 mm ?- TC used ?
