| Field of View: | ~56x38 arcmin |
| Observing Site: | Old Town, Alexandria, VA (roof of my building!) |
| Observing Equipment: | 152 mm f/9 Astro-Physics refractor with Canon 20Da at primefocus |
| Digital Processing: | Converted from Canon raw to 16bit tiff. Then in PS7, reduced to 8bit and applied auto levels. Added second exposure in new layer, aligned (make second layer partially transparent, then shift until stars are lined up, put opacity back to normal), cropped, reduced size, exported to ImageReady. In IR, made 2 frame animation, added timings (how fast to blink), text. Effect is blinking as animation switches back and forth between the two images. |
