New Image: NGC5248

#1

Post by sdbodin »

A bright galaxy in Boötes with stub end arms in short exposures, but faint extensions seen in longer exposures. Nice colors showed up in the main disc, some pink hydrogen present too. Last image from my one clear night, got only three targets, nearing 2am, way past my bedtime. I suppose I could automate the picture taking, but I really like 'hands-on' astronomy, why invest in all this gear if you are just going to click and forget, buying time on better equipment in some remote part of the globe is cheaper. Again just an hour total exposure.
