ASTRO: M45 quickie
I recently got a new focal reducer for my Skywatcher ED80 refractor, which I
tried last night. I got a few minutes of imaging between snow showers, while the clear period was only short the sky was very nice and clear. I used a blue filter for luminance, which seems to be a good idea for a blue nebula, the image is better than I would expect for just 30 minutes "luminance". Taken from the middle of Berlin with a Skywatcher ED80, modified Vixen f/6.3 reducer for f/5, G11 mount, SXV-H9 camera, 6x5 minutes for blue, 1x5 minutes green, 2x5 minutes red, combined as B:R:G:B The image can also be found at http://ccd-astronomy.de/temp2/M45colourgut.jpg Stefan |
