Images from Apogee’s Alta U9000 CCD Camera

While processing the images Dennis di Cicco recorded during his review of the Apogee Alta U9000 CCD camera, I was most impressed by the high sensitivity of the KAF-09000 chip.

The images presented here are some of my favorites. Each of these photographs were recorded through a 15 nanometer passband hydrogen-alpha filter which allowed Dennis to record large swaths of nebulosity within our home galaxy’s spiral arms, which was well placed at the turn of the year.

While examining these celestial showpieces, remember that they were captured from a strongly light-polluted location less than twenty miles west of Boston, Massachusetts, so better results can be expected when shooting from a dark location, or with a filter that utilizes a narrower bandpass. One minor point not mentioned in the article was that the CCD chip utilizes microlens technology, which reveals itself as the “+” spikes radiating from the brighter stars.

All the images presented here were recorded through a 400-mm Pentax SDUF-II lens. Each can be viewed at a larger scale by simply clicking on the thumbnail.
