IC349 Barnard’s Merope Nebula

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.

NGC 2024 Flame Nebula RGB

Wasn’t expecting it to be clear so this is a bonus. Only managed 5 of each colour though so quite noisy and Alnitak overpowers eveything.

IC410 Tadpoles in Hydrogen Alpha

The two tadpoles are about 10 light years long and places of star formation.

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

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.
