Thought I’d try and get the Merope Nebula as the whole Pleiades don’t fit in my FOV. But saw a flaw beneath Merope which turned out to be another nebula.

First real narrowband image. Strange reflections of the primary, secondary and spider in Ha and OIII images, as well as flats.
Mappings were OHS and HOS. SII didn’t add much to either image but object is strong in Ha and OIII.

NGC 1514 Crystal Ball Nebula

2018-12-06T21:42:19+00:006 December 2018|News, NGC Winter, Planetary Nebula|

A chance find, discovered on the way to finding comet 46P. Telescope was unbalanced so guiding was poor. Very noisy image so no real details. Would like to do more with this.

NGC 1514 is a planetary nebula 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.

First for a while. Far too few subs and poor focusing. Big reflection of Alnitak too.

Bad planning in that the object went behind the observatory roof after only 5 sets of exposures. Not great but better than expected though.

Good quality flats make such a huge difference. Much easier to process, especially when using the reducer.

NGC1977 Running Man Nebula

Another attempt at this with the CCD this time. Images get progressively worse through the night as equipment mists up despite attempts to stop it. Flats were useless and made it all worse so a little vignetting.

I find DSS is not giving me good results but manual stacking in PS CS3 is much better for me. I do the calibration and darks in DSS as PS is not good for that.
