NGC1760 bicolour

NB is way out of my comfort zone, but there has to be something to do when the moon is up. tried to keep the colour as close as possible to the broadband versions on the web.

there is no real point in high resolution with this object, so it is software binned 2x2 to improve the SNR. It really is a spectacular region though, with a huge cavity opened up by the bright new stars and very ragged tendrils all over the place.

250f4 Newtonian with ASI1600 at gain 100 and 200. Ha=54x600s O3=39x600s. Thanks for looking. regards Ray
