The centre of the Heart Nebula (IC1805). The image is a bicolour narrowband image with HII mapped to red and OIII mapped to green and blue, acquired with my Esprit 150.   To obtain realistic star colours,  I eliminated the narrowband stars with StarXterminator and replaced them with RGB data that I had previous acquired with my ED80.  In total the image represents 15 hours of integration time.
