It feels like a long time since I had a go at the moon, and broke that tonight. Too lazy to drag my scope out of storage so I just used the 100-400L, and experimented with the Sigma teleconverters too.

Image
400mm 1/100s f/5.6 ISO100 shown 1/2 linear size

Image
800mm 1/100s f/11 ISO200 shown 1/3 linear size

Both are raw converts but I didn't necessarily use the same settings. Notice the blue fringing on the top of the 2nd shot. I think it is also present on the top one too but to a much lesser degree.

I need to get the scope out again... I want more detail!

Nice shots, look a little too overexposed but nice and sharp. You should be able to get your shutter down to about 1/250 with the rest of the settings you are using to nail the exposure.

No part is clipping during the shot. If I were to reduce exposure they'll just get greyer but the contrast would remain the same. I did increase contrast and fiddle with levels for these.

My original intent was to have minimal noise as I wanted another go at colour enhancing them, but I've been too lazy to do that yet.

I think there is something that can be done to the contrast it just seems too light and washed out to me.

Id be interested to see the colour enhanced versions when you've done them.

I wasn't doing anything radically different than I usually do. In a quick revisit, extreme level adjustment helps but looks unnatural as the dark bits are too dark before the light bits darken. Reducing gamma seems to help more. A large negative brightness followed by a huge contrast boost looks natural enough... maybe I'll do that next time but I consider these warm up shots anyway, so I wont redo them. Still haven't moved my scope out of storage...

Digs : It hard to get any more details out of the full moon. Believe me I tried. Just wait when it's a quarter. You will get much more details at the terminator line.

So have Symtex I - you can get detail on a full moon, all I was merely alluding to was the shots above look a little washed out and could do with a bit of a contrast boost.
