지난 12월에 천문인마을에서 촬영한 M51입니다.이미지처리를 못하다가 한번 Median합성을 했더니 Add시에 나타난 이상한 노이즈가 사라지네요.덕분에 한장 올릴수 있게 되었습니다. 그리고 합성하다보니 4시 방향에 IC4263 은하도 보이네요.맞죠? FS78C EM200...

이미지 처리 연습입니다. 연습하는겸 이것저것 여러가지를 시험해봐서 균형이 깨졌습니다. 욕만 안해주셨으면 좋겠습니다. ^^; 5초 30초 등 이미지 총 20장 정도입니다. 이것저것 자질구래하게 찍었네요. Orion 8", GPD

작년 12월 27일 구름이 끼기 시작할 무렵 마지막으로 찍은 사진 이제서야 합성 해 보았는데... 실망 스럽네요.... 구름 때문인지 아님 다른 이유에서 인지 노이즈가 장난 아니더군요.... 핫픽셀도 많이 있고..... 합성을 다른 방법으로 해 보아야 할 것 같습...
