| Date | 09.16.2006 |
| Location | Okie-Tex Star Party, Kenton OK |
| Telescope | AP130 @ f6 w/field flattner |
| Camera | Canon 350D, Hutech modified type I |
| Exposure | Stack of 18, 9 minute exposures at ISO 800 |
| Notes | 40°F, 37%rh, excellent transparancy Initial RAW conversion, registration and stacking in IRIS. Noise reduction in PixInsight LE 1.02 Additional adjustments in Photoshop CS2 Inexpensive instant cold packs were used during the sequence of exposures and following dark frame acquisition to reduce camera temperature. This worked effectively to reduce noise but is cumbersome to use; both attaching to the camera and maintaining any temperature consistency. |
