alan4908 Posted December 11, 2019 Share Posted December 11, 2019 Vdb24 is a blue reflection nebula in the Perseus constellation which is embedded within the larger dark (reddish/brown) nebula LDN1442. It seems quite a rarely imaged object, I found only two examples on Astrobin and zero on SGL. It's quite an interesting image to process since the dark (brown/reddish) nebula tends to distort the star colours, particular the blue stars, pushing them towards the red end of the spectrum. It also has quite a few very bright blue stars, including one that acts to illuminate the reflection nebula itself. Anyway, here's my effort which represents just over 14 hours of integration time. The image is an LRGB and was taken with my Esprit 150. Alan LIGHTS: L: 30, R:13, G:21, B:21 x 600s, DARKS:30, BIAS:100, FLATS:40 - all at -20C. 17 Link to comment Share on other sites More sharing options...

How did the integration time split down by filter? Whoops I see this at the bottom of the image - apols. Edited December 11, 2019 by x6gas Link to comment Share on other sites More sharing options...
