B33 Horsehead in narrowband

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.

Telescope 250mm f4.8 Newtonian
MPCC
Guided PHD2
Camera Atik 460EX
Baader Ha, OIII, SII filters
Exposure(s) 15x200s 2×2 each filter
15 each of darks, flats, bias

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.
