캐논 20Da 테스트 사진

천체사진의 대가 중에 한사람인 Chuck V. 이 캐논의 새로운 천체사진용 DSLR인 20Da 로 촬영한 테스트 사진이랍니다.

Here's three test exposures I've done. I consider them all  
underexposed when compared to the total exposure time times that many  
are using. I used my AP 155EDF for all of them. All processing was  
done in Photoshop except alignment where necessary with Registar, and  
noise reduction with Noise Ninja.
