Full Moon

Posted in Astrophotography with tags , , , , , , , , , , , on 2009/08/06 by computerphysicslab

In order to catch the Moon, I took 4 single shots at prime focus through my 150/600 telescope. As I lack of a T-mount adapter I had to take them in handheld mode. After de-rotating them accordingly, I stacked them up with Registax 5 and removed the noise a little bit. I used the body camera Canon EOS 450d (Rebel XTi) at high resolution, low sensitivity (ISO 100) and high shutter speed 1/2000. This is the result after a blow up in saturation:


Aristarchus crater

Aristarchus is a rather peculiar crater. It is for me the most exciting pattern in the Moon. It is located over a weird squared area and there is an important valley near it, to its north-west. It is visible since now, 2 days before Full Moon.

The picture was shot tonight through a non-motorized 150mm (6 inches) reflector using high definition video capture with Casio Exilim EX-FS10.

Humboldt crater

Humboldt crater as seen with the Vixen 12×80 binoculars. This is a big crater but very near to the Moon limb. One day after full moon, Humboldt delivers high contrast images due to its shadow. The day this shot was made, the Moon libration wasn’t the better one to view Humboldt in its extension, but edge-on. The inner central peaks are visible.

Gauss crater

Gauss is the big crater near Mare Crisium. It is visible one day after Full Moon, because this is the exact moment for its best shadow projection. Berosus and Hahn are the two smaller craters near Gauss. It is visible a tiny central peak inside Hahn crater. And inside Gauss we can barely spot a shadow that Gauss B casts. Gauss B is a small crater to be guessed in Gauss.

Almost Full Moon

Here we see a 13 days lunation Moon, almost full. Registax 5 did the work of stacking and wavelets. Focus was not perfect but wavelets fixed it. I multiplied the red channel to the green channel in order to enhance the image contrast.

The Moon highly saturated

Usually we see the Moon as in a gray scale picture, with no color details. Nevertheless the Moon has different hues depending on the chemical composition of the terrain. For example, Mare Tranquillitatis has a blue tone due to its titanium high density. Processing a Moon picture computationally, we may exaggerate its colors, giving high saturation to RGB colors. In the resulting image, Mare Tranquillitatis is the most blueish dark area. Equipment: Telescope Tanzutsu Catadioptric 114/1000.
