Feels like a long time since the last one? Got home from work, looked up and saw a half moon high in the sky. So I shot it.

Image
1325mm, 1/50s, f/13, ISO200 - click image to go to dA to download original size 1.8MB.

I tried things a little different this time. Normally I'd leave the ISO fairly high to keep shutter speeds down. I kinda hope a fast shutter will mitigate wobbly air blurriness. But I wondered what a low ISO shot would be like. I'm quite surprised but it does reveal more fine detail that would normally be lost to the high ISO noise. Not that the 50D is bad at ISO1600, for normal shots it's highly usable. But in this case we have low contrast high detail, and a lower ISO does reveal that bit more detail.

PP: fiddled about in ACR with high contrast and slight desaturate as the blue sky got rather too blue and unnatural otherwise. Crop, slight sharpen and save to jpeg.

I did also try with the 2x barlow, but the shots I got from that suffered from a bright spot in the middle of the image. I've long suspected I had that, but I guess with the bright sky it made it really stand out this time. Will have to find and dull down the offending reflecting surface later.

Nice shot popo... the Moon is normally sufficiently bright to allow low ISOs and still have quick enough shutter speeds to avoid shake. I like that you've kept the colour of the sky, which is trickier than it seems when photographing the Moon.

Thanks. I tend towards higher ISOs due to the scope I use. It's f/13 to start with, and effectively f/26 if I stick the barlow on it. I need to dust the sensor before I try that again!

As for the sky, in this case it was early evening as I just got back from work. Now the days are getting longer again there's more daylight and a chance for blue sky shots. I think there was a slight haze today working against me. The contrast was very low so I had to boost contrast a lot in PP.

Another day, another moon. Tried ISO100 and wanted to do an enhanced colour moon.

This is what I ended up with:

Image
1325mm, 1/8s, f/13, ISO100 and a whole lot of saturation increase.

The more vivid blue and orange bits match up with other ones you can find on the web, but I'm not so sure about the greens and yellows in this case.

I made a big mistake in the process. I had turned on jpeg only from a duck shoot earlier today, and forgot to put it back on raw. By the time I noticed and went back to retake the shots, thin cloud had moved in and I couldn't get a clear shot.

They do say the moon is made of green cheese. Looks like a nice piece of Stilton there!

I've seen blue, green and white growth on (edible!) cheese, but never orange!

At the risk of jinxing it, the weather is clear so far today so maybe I'll have another chance later.

Cloudy tonight, so no new moon shots. Looking around, I saw there was a new version of registax. First I fed it my saturn pics and didn't get anywhere. Instead I fed it moon shots from the same session which really helped with the noise. A bit more fiddling later, I got this:

Image

I'm really happy with this as it is so much cleaner than the earlier colour enhanced image. Now I hope for more clear weather on full moon so I can do the whole lot in one go :)

PP: 18 shots aligned and stacked in registax. Export at 16 bit tif, open in PSE. Crop/rotate/flip. Duplicate layer. To one correct white balance, gradually increase saturation, then blur. To other desaturate and sharpen. Set as colour/luminance respectively. Flatten, resize, sharpen, save. Or something like that.

Just a quick one for tonight...

Image

I find crescent moons are hard as the absolute brightness isn't so great for my kit. Still have the bright spot and flare when using the barlow so those images were not really useful either.

Another quick one. Couldn't resist when I saw it glaring down at me.

Image

Air quite wobbly tonight. Experimented with ISO100 and 200 which pretty much guarantees a blurry shot. Image is composed of 8 shots. Moon shot 4 times each top and bottom half. Pairs taken and stitched in photoshop. Those whole moons were then registax'd before getting the colour enhancement treatment back in photoshop.

Comparing it with the previous one above, I don't think I got the colours as good this time, possibly as a side effect of the moon being so big I had to stitch it. Before it was just small enough for a single shot so easier to stack more.

A quick moon from last night. Realised I haven't done one in a long time.

It was low on the horizon in the early evening so lots of wobbly air to go through.

Image
Nexstar 4SE - 1325mm f/13
1/20s, ISO160
PP: Mild HDR from single raw, noise reduction, yet more level tweaks. Slight crop before resize.

Moon seems to be slightly smaller at the moment as it comfortably fit in a single shot.

Nice shot, though I notice you said RAW. Have you finally converted to the RAW workflow?

Still undecided. Unless there is a specific need (like extreme contrast scenes, or long continuous burst needed), then:
If space is not critical, I shoot J+R and work off the jpeg where possible.
If space is moderately critical, I shoot raw only.
If space is very critical, I shoot jpeg only.
For most normal shooting, I find jpeg is more than adequate.
