Nova Dephinus 2013, the new nova (Latin for “new star”) was discovered Wednesday (Aug. 14) by amateur astronomer Koichi Itagaki of Yamagata, Japan, at 2 p.m. EDT (1800 GMT) in the constellation Delphinus EOS KISS X3 Standard lens at 18mm ISO3200 10 seconds exposure ちょうど2ヶ月前の写真と比べてみました。双眼鏡、400mm焦点の望遠鏡では、ずいぶん光ってきれいでした。この写真、ガンマーをかけて星を出してますから、輝度の参考にはなりませんので。Before-After の写真はCS5でアラインメントしてあります。
