Date: | 01/04/22 | ||
Location: | Backyard Observatory, Carlsbad, CA | ||
Telescope: | William Optics Star 71 refractor, 350mm fl f/4.9 | ||
Camera: | QSI 683 wg with Astronomik Ha and SII (6nm) filters | ||
Mount: | Losmandy G-11 Gemini I | ||
Exposure time: | 2 hrs each of Ha and SII (15-min subs) | ||
Exposure time total: | 4 hrs | ||
Notes: | Sky conditions, and humidity rendered the OIII data useless - a common occurrence from the suburbs during Winter. Was able to salvage this 4-hr expsure due to the abundant Ha in this region. This is a bicolor image with Ha assigned to red and SII to green. Ha channel also used as luminance layer. FOV = 177 x 133 arcmin, Image Scale: 3.18 "/pixel |
