Hello,
I am, like many others, deciding what camera is the best for my needs.

I am wondering if there is someone who is thinking of using their cameras to take pictures in a night sky.

I do not know if digital cameras are ready for using in astronomy and long exposures pictures ??
I do not know if there are accesories for attaching a camera to my telescope ??

What is the best camera for night pictures ??
...of course I would like to use the camera for other generic purposes.

Thanks

Fmartin,

All of the 2-3 MegaPixel cameras with manual controls, 3X zoom, and THREADED lens do a good job. I have used a Nikon 950 with excellant results. Depending on what you want to do and what equipment you currently have will be a starting point. The real challenge is connecting the camera to the telescope or scope. The connection is called "afocal" and you actually hold/attach the camera lens up to the scope/telescope lens at full zoom.

If you are only interested in moon shots then a 12X scope with work fine (12X scope times 3X Zoom) = 36X for the moon. One company makes a threaded lens for digital cameras and scopes.

If you are looking for a larger telescope the problem is still adapters. Most have been homemade adapters. If you get a telescope make sure it has the standard 1.5" eyepiece. Some adapters are beginning to show up to fit the 1.5".

You can find a reconditioned Nikon 950 for around $410 (search the messages) http://www.ubid.com/cat/1227.asp will have some and I think Ritz Camearas also have some. Do a message search for more informations on Scopes & Telescopes.

Good luck with your hobby.

Check out my friends web site. He tried a D1 and a 990 and was dissatisfied with them as astro cameras because of the noise. What you want is a cooled CCD focal plain.

Correction, the standard telescope lens/eyepiece is 1.25"

I think that astronomical photography will be a niche for traditional film for a LONG time to come.

The essential charateristics for this type of photography are (1) very long exposures, and (2) high resolution needed to capture minute detail.

Digicams don't do well with long exposures. They don't work the same way as film.

Film still has much higher resolution. In many cases the resolution is theoretical or not needed, but the type of setup needed for astro-photography, an SLR and the camera is mounted, indicates that you will indeed be taking advantage of the superior resolution of the film.

This is correct for "deep sky" pictures of nebulas, galazies and so on. Digital cameras are useful for bright solar system objects, Mars, Jupiter, Saturn and Moon:

Hard to say. Cameras vary from sample to sample, but most > 2Mp cameras can do some good at night:
