Re: [APML] CCD experiences

Hi all,

I have to agree to Loke's opinion. For me CCD is an additional tool in astrophotography. Till now, I'm only working with film and I can see where the limits are. Small galaxies and clusters are sure better resolved with CCD at the same focal lenght. Both techniques has their advanteges and disadvantages and worth to work with.

Tony,

I must say that I am quite surprised. This is quite a big decision. I had always thought that there were advantages and disadvantages to both CCD or film. One is better at high resolution narrow field work and the other for widefield work.

Hello,

    As some of you might have guessed from my message to Bobby, I have parted with CCD completely. What at first seemed like an amazing medium turned out to be something quite a bit different... my greatest disappointment has been with the "noise" issues... it's not enough to take good RGB exposures... after that comes a lot of dark frame exposures and flat fields... to get an image like Rob Gendler's one must go to unbelievable lengths. I also don't have the steadiness of seeing that a CCD necessitates, but I do have dark skies. So I am returning to film, only this time I am going to concentrate on slide films... I think they are sharper than negative films.

Philip posted a very good summation of CCD vs. film quite a few months ago... I would like to add that although CCD is in essence a tricolor process, the noise issues make it a different experience. Not much else to say about this... I wish I knew back then what I know now...

    Have a good one,

        Tony
