Colour saturated Moon with 40D

Hello

With all the rain we have been having in Brisbane, I’ve been looking at some recent images to see if I can improve them. Here is one I have been playing with, a colour enhanced version of the recent Moon photo I took at the prime focus of the Tak Mewlon 180 with the Canon 40D. Focused using Remote Live View, with an exposure of 1/50 sec at 100 ASA.

All I did was increase the saturation in CS3 and the colours and hues just popped out!

Warning: File size=160K at 1300x1200

Cheers

Dennis

Wow Dennis amazing image!

It certainly gives you a different perspective when compared to the typical B&W image.

Matty, that's exactly what I was thinking when I looked at the image! Great image Dennis. What causes the brown tinge vs the otherwise grey mare?

Thanks for the nice comments guys – have a look this LPOD link to some Zac Pujic colour saturated images for some details on which elements produce these colours. Zac is an IIS member from Brisbane.

Cheers

Cheers, Paul.

Nice shot. It has me thinking about false colour composite narrow band imaging of the moon, including into IR.

I know its garish but for differences between different topographical features and their composition you can take it further - see attached. But I prefer the subtleness of yours

Hi Allan

Nice work and not too noisy. I did initially take it almost that far, but when it began to look like technicolour dog vomit, I backed off the slider!

Cheers

Dennis

Beautiful Photo. Focus looks perfect to me.

Thats the kind of photo I can hope to capture when I get some decent gear for the job.

Well Done.

Geoffro.

Hi Dennis,

Man this photo has to be one of the best Moon photo's I have ever seen. Every time I come into the Solar System forum I just have to have another look.

Regards

Daniel...

The link listed below illustrates a slightly more complex technique for producing some amazing coloured moon shots, that avoids some of the limits using saturation control.

Thanks again for all your nice complements; I’m glad you enjoyed the photo. Our Moon is a rewarding celestial target as it is so close and has an amazing variety of moods and detail which are always changing depending on the season and the phase.

There is a little softness in the image at the edges as the large sensor is quite challenging for the central, relatively small, in-focus field of view of the Dall-Kirkham design of the Mewlon.

I’ve found that the combination of magnified focusing via Remote Live View and using the Mirror Lock Up on the Canon 40D have significantly improved the sharpness on my DSLR lunar images compared to my trusty old Pentax *ist DS which I still treasure.

Cheers

Dennis

That's a terrific image, Dennis

Super sharp and subtle as far as bringing out the colours is concerned.

Great stuff.

Brilliant image, Dennis. Great to see something from you again! It's been a very dry spell from the Dennis imaging factory.

I hope you get some clear skies soon!

Dennis,

That is a wonderful image. Questions:
Is that a single image?
Did you take it in RAW mode or Jpeg?
And finally, what white balance did you use - daylight?

Hi Glenn

Thanks for those nice words.

At the F12 prime focus of the Mewlon 180 the gibbous Moon won’t quite fit on a single frame with the Canon 40D, so I resorted to taking two photos slightly offset, then using CS3 to automatically create a mosaic from the two panes.

Here are the two frames and the Exif details of one of them as a screen capture; I haven’t figured out yet how to capture the Exif data as a text string.

The captures were RAW and WB was left at Auto. 1/50 sec at ISO 100.
Essentially, it is a single image although it is in fact a mosaic of the two segments.

Cheers

Dennis
