If I change "sunPos" to "moonPos", would this still work?

It's a lens flare GUI, and I'm trying to see if I can make a moon lens flare just by changing a variable.

local camera=workspace.CurrentCamera
local host=script.Parent
local lFlares={}
local collision

for q,w in pairs(host:GetChildren()) do
  if w.Name:sub(1,9)=="LensFlare" then
    lFlares[w]=tonumber(w.Name:match("LensFlare(%-?.+)"))
  end
end

function findFlareCoord(cordFrame,sunPos)
  local setCoord=cordFrame:pointToObjectSpace(sunPos)
  local fov=math.atan(math.rad(camera.FieldOfView))
  local z=-setCoord.z
  if z>0 then
    local x=(setCoord.x/fov/1.2)/(z+1)*(host.AbsoluteSize.y/host.AbsoluteSize.x)
    local y=(setCoord.y/fov/1.2)/(z+1)*-1
    return x,y,true
  else
    return 0,0,false
  end
end

local stepped = game:GetService("RunService").Stepped

while true do
  local x,y,z=findFlareCoord(camera.CoordinateFrame,camera.CoordinateFrame.p+game.Lighting:GetSunDirection()*5)

    dist = (camera.CoordinateFrame.lookVector - game.Lighting:GetSunDirection()).magnitude * .3
    local sunCast = Ray.new(camera.CoordinateFrame.p, game.Lighting:GetSunDirection() * 999)
    local hitPart, hitPos = workspace:FindPartOnRayWithIgnoreList(sunCast,{game.Players.LocalPlayer.Character, camera})
    collision = hitPart and true or false

if z and (game.Lighting:GetMinutesAfterMidnight()>335 and game.Lighting:GetMinutesAfterMidnight()<1105) and collision==false then
    for lFlare,pos in pairs(lFlares) do
      lFlare:TweenPosition(UDim2.new(0.5 + x*pos,-lFlare.AbsoluteSize.x/2,0.5+y*pos,-lFlare.AbsoluteSize.y/2),"Out","Quad",0.01,true)
      lFlare.Visible=true
    end
    local shineTrans=(0.2-(math.abs(x+y)*0.5))
    if shineTrans>=0.2 then
      shineTrans=0.2
    elseif shineTrans<=0 then
      shineTrans=0
    end
    host.ShineOverlay.Transparency=1-shineTrans
    print(x)
  else
    for lFlare in pairs(lFlares) do lFlare.Visible=false end
    host.ShineOverlay.Transparency=1
  end
  stepped:wait()
end

Instead of asking, you can try it by yourself.....
