王兄:
可先上NASA之Website:
http://hubblesource.stsci.edu/sources/illustrations/constellations/那兒有NASA志工群努力增補掃描中之古星圖23/88個( 17th century Uranographicarum star atlas by Johannis Hevelius. )
下載這些無償公用的PNG檔後,以Photoshop等軟體之圖層疊加及縮放,旋轉,平移調整後,
依原稿情境或色階需求,適度調整疊上之png檔頭透明度,
再整個另存就成了.
Try it.You can always make it,too!
(要記得使用前先鏡像反轉,因它們都是天球外往內視的)
