This is an easy one as it is an A0 spectral type.

I just love this nebular. Star forming area of dust and gas. This is a better image than before Xmas. Two sets of exposures to get the core and the dust areas. Techy bit: 3 x 100sec per RGB and 4 X 130sec L merged with 3X 60sec per RGB and 4 X 60sec Luminance. […] Ok I have taken quite a good image of this tricky nebula. Take a look on the web and look at some of the images. 4 X 400sec per RGB. No darks. (had to manually take out a couple of hot ones) RGB Image of Cacoon Nebula […] Not bad image considering the gusty wind. Just 3 X 300sec per colour Managed to get M33 as it was a clear but very bright night. Finally fixed the problem of round stars on long exposures. 6 X 600sec 8inch RC Astrograph and SXVR-H18 at -20degC Orion – Horsehead nebula |
