ASTRO: M88
Another one from my recent trip to northern Germany.
Of course I have imaged M88 before, but there was definately room for improvement. In the first night there were very heavy gusts of wind, which even led to an official weather warning. Still when the sky cleared in the course of the night I set up my scope and decided to get some colour data with 2x2 binning (usually I take all frames unbinned). The binned images were still shaky. Next two nights I got some unbinned luminance to go with the colour data. Image scale of the final image is 0,63 arcseconds/pixel. There was some disturbance during the luminance frames by northern lights, but I won't complain about that as I have never seen them before. You had to know they were there to see them. Taken with a 10" Meade ACF on a G11 mount, Trius SX694 camera, 18x10min lum, 8x5min RGB each. Stefan |

Sounds like my weather luck of late. Fortunately color data can withstand those issues without serious damage so it came out quite well.
