The black hole image 1) Needs to be square. 2) Although the black hole in the image is extended only on one side, I need a full black hole image. 3) The center of the black hole should be in the center of the image. 4) The background should be transparent. 5) The lighting effect in the image of black hole should be provided with another image, I shall overlay both images to make that effect. The star Image 1) Need four png with different brightness level of the same star. 2) The background should be transparent. 3) I will be running the images in animation of a blinking star. So please keep that in mind. Need psd files as well. Regards, Jehandad
