Description

The CCD camera has revolutionized the art of astrophotography. This discussion group is for those who would like to learn how to take astrophotos. The group is moderated by the author of the book The New CCD Astronomy - Ron Wodaski.

The focus of this group is on providing detailed feedback for beginners and intermediate CCD imagers. You will find the information you need on how to focus, expose, and process images. There are hundreds of tips here on CCD imaging, as well as product reviews and answers to common questions. You can also post your images and get critiqued, or submit your suggestions so that others can learn from your experiences.

And if you just enjoy looking at the images of celestial objects, please feel free join us!

This group is designed more like a classroom and most other Yahoo groups. We have multiple teachers and many students. We ask that posts be polite, on topic, and that members take responsibility for their posts. That means that the group comes first - post facts, not opinions, so that others can learn.

Note: we have special requirements for commercial postings. A message from or on behalf of a commercial product or company must meet the following requirements:

It must be brief; It must not be promotion or hyperbolic in tone; It must not contain marketing materials; It must link to a web page with additional details.

Ron Wodaski and co-moderators:

  • Mark de Regt
  • Randy Nulman
  • Mike Dodd

Re: Nice M51 image with one-meter scope
... Have you tried pre-flashing? (I would expect such a camera to have a built-in flasher). Stan

... It is probably not smaller when normalized for pixel size. A CCD with smaller pixels and shallower well can take up just as many electrons per object

It's always about signal relative to noise. The best choice would be the setup with the best S/N. That would mean including all possible sources of noise -
