I haven't been able to get to my observatory despite some lovely clear skies! Ice and Snow, minus 4, minus 5... Oh well, even if I did make it the light pollution is 10 times worse because the snow reflects street lights up into the sky. Plus I'm saving petrol (carbon). I created this misty effect by building a mask using the luminance value, inverting it and applying a 5 pixel gaussian blur. Any guesses as to what this mystery object is? (Hint: there's an easy way to cheat).

ReplyDeleteSorry try again. Hi Dan, it's NGC7023 The Iris Nebula.
ReplyDeleteWell done! I like to put in some interactivity. Is that the name of it? I've never heard it called that. I suppose most nebulae have names if you research hard enough. I guess you could just plate-solve it. Happy christmas.
