Excellence in CCD imaging is an admirable pursuit and I wish you the best of luck if that is your goal. My philosophy toward astrophotography is that I want it to be fun, first and foremost. My objective is to capture on disc levels of detail in deep sky objects that I cannot see in the eyepiece. I am not a perfectionist. My feeling is that if you are working hard at getting your CCD images and are not having fun, then you are doing something wrong.
Life is too short and there are too many objects out there to capture.
If creating the perfect CCD image is your goal, then go for it. But if you are like me and are out to 'observe electronically', capturing what you see along the way, then you have come the right website. With the above in mind it should by now be clear that you won't find picture perfect images on my website, but you will find lots of them as time goes by. I take data shots and dark frames. I do not take multiple darks and average them.
