Colour saturated Moon - Brisbane 29th Spet 2023

[Dennis]

Taken on 29th Sept 2023, I have increased the colour saturation of this Moon image to reveal areas that are rich in Iron and Titanium.

Canon EOS R7, 1/200 sec ISO100 F8, 30 frames processed in Autostakkert!3, Wavesharp and PS CC.

From https://lunar.gsfc.nasa.gov/science.html

Colors on the Moon are dominantly controlled by variations in iron and titanium content. The mare regions have low reflectance because they contain relatively high amounts of iron oxide (FeO). Some mare basalts contain unusually high amounts of titanium oxide (TiO2) in addition to iron oxide, making for even lower reflectance. TiO2 also shifts the color of the mare from red to blue.

Nice work Dennis, the colour differences are most striking in your image and highlight the mineral variations well.

Thanks Jeff, I appreciate your comments.

For this image, after Aligning and Stacking in Austostakkert!3, I used Wavesharp instead of Registax6 to perform the deconvolution/sharpening.

I noticed that Wavesharp produced better results in particular on the highlights. The darker Maria were also slightly less "muddy".

The brighter (almost blown out) rims of craters, small craterlets and the rim of the Moon were much improved when I blinked the Registax6 version with the Wavelets version.

Nice one Dennis I actually really like the saturated look for full moon shots.
Do you use wevesharp for other planetary imaging too?

That is very interesting , about Wavesharp compared tp Registax, might have to give it a try out.

Hi Dave

I have only used Wavesharp for these Moon shots as they were taken with a DSLR, so no experience with planets yet.

In the past, Registax has had some trouble with certain DSLR formats such as full frame, where the pixel dimensions of the image are too big, so Registax seems to auto crop them.

Hi Jeff

The interface took a while to get used to in terms of moving the Region of Interest and then getting Wavesharp to render the entire image,

I just kept pressing a few buttons and it seemed to work, so I'll have to sit down and learn how to use it properly.

The big attraction for me was the ability to process larger DSLR files. It was then a pleasant surprise to compare the Registax output and the Wavesharp output and by blinking them, notice that Wavesharp at the pixel peeping level was better in those areas.
