Description

In the Perseus arm of our galaxy we find two spectacular nebulae, the Heart (IC 1805) and Soul (IC184 nebulae. Located around 7,500 light years away from us both cover a wide region of the night sky, in the Cassiopeia constellation.

Both nebulae have high emission on the red spectrum and especially in the H alpha line. With the use of this filter we can capture its structure. This image shows the Heart Nebula, IC 1805, and its core, the Melotte 15 nebula.

It's my first im,age using the dual Takahashi FSQ setup. FSQ106 EDX4 was used to capture Ha3nm data and RGB for stars, while FSQ85 was used to capture [OIII] and [SII] data.

The color combination to obtain this image has been the following. I processed the nebula without stars and composed the following palette:

R= [SII] *0.7 + Ha*0.3
G= [OIII]*0.7 + Ha*0.3
B= [OIII]

Then I added the RGB stars to the resulting nebula image.


I hope you enjoy the image as much as I've done. Thanks for taking your time on this site.
