NGC 2264 Christmas Tree Cluster narrowband

After a HOYS-CAPS session added narrowband. Rat’s head in there?
No more MPCC and stars are much sharper at the edges.

B33 Horsehead in narrowband

By |2019-01-14T16:26:53+00:0014 January 2019|Categories: Dark nebula, Narrowband, Nebula, News, NGC Winter|

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

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.

Horsehead, Flame and Alnitak

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

Processed (very harshly to get anything out of it) in Nebulosity 3, Photoshop and Lightroom. Noise reduction very heavily used!

Cone Nebula and Christmas Tree Cluster

NGC 2264
Star forming nebula and Open cluster, Monoceros
Mag 3.9, size 20′
2017-01-29
200mm f8 RC at f6 (Revelation x0.75 reducer)
Piggyback guiding with 70mm f/7 refractor
L 5×240s 2×2, RGB 5×120s 4×4 Darks Bias Flats
Atik 460EX (-25C), LRGB filters, IDAS P2 LPR filter
Captured in APT, Processed in Nebulosity3, PS CC, LightRoom

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.
