This image is a mosaic of six shots of the moon through the telescope eyepiece using eyepiece-projection directly onto the camera's CMOS chip.

Telescope is an Orion Skyview Pro 6LT 150 mm f/8 Newtonian reflector. The eyepiece used is a 25 mm Sirius Plössl.

The image was enhanced in the Lab color space to increase color saturation on a separate layer, and blend it with the original image in color mode. This method can bring out some natural, muted color variations on the lunar surface.

Hi Gunnsi, thanks very much.

Here is a link with a great discussion of the process:


The process described on that site uses the Hue & Saturation command in Photoshop to generate the saturated colors. I prefer to convert images like this to the LAB color space, because I think it gives me more control over how the color saturates. LAB is a color space where one channel (L) represents all the Luminosity information in the image, including all contrast and details. The A and B channels take care of pure color vales without any contrast and detail (A = blue to yellow, B = green to magenta). You can adjust the curves for the A and B channels to emphasise the saturation of those colors (steeper curves give more saturation). LAB is an amazing color space for color correction, and for anyone who is interested in understanding it in great depth, I highly recommend the following book:

Photoshop LAB Color... By Dan Margulis

Gunnsi, I hope that helps. I know it's not really a step-by-step in LAB, but if you follow the information on the 'color the moon' site, I think that could get you started. Let me know how it goes!

This is the best lunar photograph I have ever seen.
Is it by any change possible for you to make a step by step lessons here for us novice people on how you did this.
This "Lab color space" how does it work?
