I have reprocessed my recent image of The Heart Nebula IC1805 to commemorate Valentine’s Day. For the Hubble Palette image this time I have used the naturally colored stars from the RGB (Color) image. The process involved making the Hubble Palette images starless and then inserting the stars.
I'm very humbled that this image was selected by Steve Astromag's AmateurAstrophotographyEzine on Instagram as Image Of The Day

Derived from its Valentine's-Day-approved shape, its nickname is the Heart Nebula. About 7,500 light-years away in the Perseus spiral arm of our galaxy, stars were born in IC 1805. In fact, near the cosmic heart's center are the massive hot stars of a newborn star cluster also known as Melotte 15, about 1.5 million years young. A little ironically, the Heart Nebula is located in the constellation of the mythical Queen of Aethiopia (Cassiopeia). This deep view of the region around the Heart Nebula spans about two degrees on the sky or about four times the diameter of the Full Moon.
I also made a video from the 4 images I used showing the fade from Hubble Palette and Hubble Palette Starless to Color to Color Starless.It can be viewed here:

In this Hubble Palette version the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. While the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image.
Captured over 5 nights in October 2019 for a total acquisition time of 31.8 hours.
