IC1805 - Heart of the Heart Nebula in HST palette


Recommended Posts


This is another image I started just over a week ago as a try out to see how it went taking 30 minute sub frames. I managed to get 10x30 minutes of Ha last week and last night was clear apart from two 10 minute breaks for clouds. It was taken with a Takahashi FSQ106ED at f5 and Starlight Xpress H9 on a Paramount ME, auto guiding was by a Lodestar camera and OAG using dithering.

Exposures were

10x30 minutes Ha

4x30 minutes OIII

7x30 minutes SII

These were then mapped to the HST palette. Using 30 minute sub frames does make the processing a lot easier as less usage of levels and curves are required to bring out the detail

The Ha version of this and earlier attempts at this object can be seen in the image gallery on my website


and a full size high resolution version can be seen at the following link

Thanks for looking

Best wishes and clear skies
