The colour is subjective but processed to highlight the different light wavelengths.

Tbh most nebula names are pretty random

It is an rgb image combined with data using a hydrogen alpha filter which only allows light through in hydrogen alpha part of the spectrum

Great image Kev. 👏

Typo IC 1848 not 1805

Thank you

Good question, seeing as the remnant is about 90 light years across so probably at least 1.

Thank you

You are seeing a nebula called the heart nebula. It is an emission nebula in the constellation of Cassiopeia and it is comprised of glowing gasses including hydrogen and oxygen which are highlighted in the image by redish and blue colours

Yes two telescopes with 2 different cameras. :-)

Thanks I am listing kit I used to take the image. 😀

Thanks - Dual band filters with both colour cameras.

Thanks Dave

Great definition in the tail Dave., What kit are you using?

Thank you
