LRGB of Ring Nebula 10.26.2104


Last night was truly as perfect a night as anyone could wish for: good transparency and good seeing--a rare combination here in Indiana! As I was setting up the scope, I noticed a bright light crossing a little south of the zenith. At first, I thought it was an Iridium Flare, but, as it showed no signs of fading, I quickly realized it was the International Space Station. I have never really looked for the ISS before, so it was a real treat to see it pass over Indiana. 

Last night was my first attempt to do LRGB imaging. I had done one or two RGB images of Mars earlier in the year, but I had never tried to image deep sky objects and to add the luminance channel.



Here is my first attempt at an LRGB image. This image was taken with the ASI120MM and combines RGB and luminance filters. My combination is not the best as I am not a Photoshop expert, but it's not too bad for a first attempt at "multichannel" imaging.
