Binary star measurement. Using the time variations of the eclipses we are able to calculate the orbit of possible companion objects big enough to have an effect on the orbital period of the binary pair. The picture below is the plot of light magnitude from the binary pair. The timing of this minima is […] A star 465 Light years away from earth. Has a planet around it that was first confirmed in 2012. So I thought I would use my observatory to look at the transit of that planet. A very small dip in the light from the star. HAT-P-12b planet Unfortunately I could not get the entry […] The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.A supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The distance to […] This is an easy one as it is an A0 spectral type. Type Ao with SA200 grating 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 |
