NGC 1514 - The Crystal Ball Nebula

Recommended Posts

NGC 1514 is a planetary nebula in the constellation Taurus that was discovered by William Herschel on November 13, 1790, describing it "A most singular phaenomenon" and forcing him to rethink his ideas on the construction of the heavens. Up until this point Herschel was convinced that all nebulae consisted of masses of stars too remote to resolve, but now here was a single star "surrounded with a faintly luminous atmosphere." He went on to conclude "Our judgement I may venture to say, will be, that the nebulosity about the star is not of a starry nature".

It has since been conjectured that the nebula in fact envelops a tightly orbiting double star with a period of up to 10 days. Gas is presumably expanding away from the larger star of the pair.

Ooh not familiar with this, looks a challenging little thing.  Great job.  Out of interest, where is the Ha?

Thanks Martin.  I used the Ha to pull out more structure detail of the nebula in the synthetic luminance, but only used the RGB for colour.

Great image, I like the detail in the nebula and the nice star colours. 

Cheers, Ian

I found this object the other night, never having heard of it before. It is lovely.

Your image is much better than I managed - sky wasn't too transparent and ice forming on everything. Good one!

Thanks Mark.  It's a pretty target, but very small - and I found it quite challenging.  It needs a fair bit of data to be able to pull out the structure of the nebula.
