The Black background Didn't made the sight nearly invisible against the sky and water. The white background made it allot better on my end, this is what i see

The gunsight is from an old star wars game and shouldn't be as practical as some of the others that are out there, although funny enough my aim has improved since I started using it.
Interesting, if I save your bitmap directly to my sights folder and use it, the white mask acts like a black or magenta mask. If I open it in an art program first to look at it and then use it. The game shows me the white mask. Maybe Waffle can explain that phenomenon.
Its a 100Mil diameter with cyan vector rays at 27 degrees, medium blue center dot\oblong, and a medium blue rectangle 50Milx85Mil. But, if you don't use zoom, the thickness of those ray structures are ideal for none zoomed shooting. 15 pixel wide lines show up very well in non zoomed mode. I will venture you use the horizontal sides of the rectangle for low E 10-20 degree deflection shots while relying on the vector rays in higher E turns and to point down at a con passing under you to line up the vector for a deflection shot. The bottom of the dark blue rectangle you probably use for dive bombing and determining elevation for firing from above while diving down on a con. Over the years some players have liked the HTC 6-star K14 reticle for the same reasons.
Why don't you make a cleaned up copy of it that looks like a WW2 gunsight would possibley have projected it? Going through the steps of accomplishing that will teach you a lot about making gunsights. Just use cyan and medium blue and it will stand out like your screen capture. You can make your center blob a round dot.
You can do this with a medium blue 50Mil ring then pull cyan 27 degree 15 pixel wide lines. Then place a 6-12 Mil cyan dot in the center. By the way, your center dot in your bitmap is below the center point the convergence app aims at. Essentially giving you a relative speed compensation out to about 400yds with a 50 cal in a level 6 chase.
The center dot being a vertical oblong, makes me wonder if the actual bitmap in it's game, isn't wider and the rectangle actually a square with a round dot in the center. I seem to remember years ago seeing the reticle from that game and the center was a box while the ray vectors went out farther on each side representing the wings of the X-Wing you were flying in. Did you compress the sides to fit this game? Weren't the ray vector lines more uniform across their length and less stretched tear drop shaped, with the green dots on each end representing the blasters?
