Render an accurate image of 3D Moon

I want to create an accurate image of a 3D Moon model as if it were seen by a camera. I am using a rendering software to compare the image resulting (POV-Ray).

I am using the code below to produce the image on Matlab and the result is

With POV-Ray, setting the same value for distance of the moon and radius I obtain

I obtain with Matlab a smaller Moon with respect to the POV-ray one and I am sure that there is some camera issue that Matlab does not take into account, do you know which one of it should it be?

% Create Moon Ellipsoid
[x, y, z] = ellipsoid(MoonCam(1),MoonCam(2),MoonCam(3),...
    R_moon(1),R_moon(2),R_moon(3),2000); % Moon ellipsoid centered at MoonCam

% Init Figure
figure()
axis equal
hold on

% Plot Moon Triaxial Ellipsoid with textures
planet = surf(x,y,z,'Edgecolor', 'none');
moon = imread('moon.jpg');
set(planet,'FaceColor','texturemap','Cdata', moon,'BackFaceLighting','unlit')

% Camera Settings
set(gca,'CameraPosition', [0 0 0], ... % Position of camera at LUMIO center
    'CameraTarget',MoonCam,... % Target of camera
    'CameraViewAngle',6,... % Field of view of the camera
    'CameraUpVector',[0 1 0], ...% Camera Up vector (y axis)
    'Projection','perspective', ... % Projection of ccamera
    'visible','off',... % Untoggle axis
    'Color','k',... % Set background color of the rectagle to black
    'xdir','reverse') % Set x-axis positive toward right

% Image settings 
set(gcf,'color','k',... % Set all background to black
    'PaperUnits', 'centimeters',... % Units in centimeters
    'PaperPosition',[0 0 8.67 8.67] ); % Set Image to 1024x1024 pixels (or 8.67x8.67 cm)
