I Finally PP'd my lunar eclipse shots.

All except last one taken at f11, 1/400, ISO400, with 70-200VR + TC20EII @ 400mm.

I had trouble getting the full eclipse image sharp. Anyone else have this problem? I was manual focussing.

Brad I like this a lot. I understand why it's composed the way it is but the anal retentive in me wants to see the orange moon first not last - go figure.

I looked at the large version - I wouldn't be overly concerned about softness since when this is printed (and you will do so I hope) it will be viewed from enough distance for that not to matter

Nice shots Brad. The good thing about living in the gong is we get a free red glow many nights of the week :)

no focus problems at all, just focus manually at the start of the evening when the moon is nice and bright, and don't try to adjust it later ;)

What exposure did you use during totality? I suspect its a combination of image motion during a long exposure, with maybe some camera shake.

I cant remember off the top of my head. Around 5 or 10 seconds.

I was using a solid tripod + self timer so shouldnt have been any camera movement. Maybe some vibration due to mirror slap though??

ahhhh... 400mm for 10 sec on the moon= trailing. The sky moves at 15"/second and a rough rule of thumb for 35mm was keep the exposure under 600/focal length and trailing will be minimal. For DX sensors 400/fl would be more appropriate, so if you went 10 sec thats 10X as long as required to show trailing. I didn't need to go over about 2.5 sec I think, at 200ISO during totality, but I was working at f/4 ;)

I didn't stop to think about trailing. I'll remember that for next time.
