Amateur Astronomy from Edinburgh

This website is a place where I can post my images purely for the fun of it. You can find more information about the equipment I use on the About/Equipment page.

To give me something to aim for, I have set up pages to get as many Messier and Lunar 100 objects as I can. The Deep Sky page is for objects not in Messier’s catalogue and includes some more recent lists such as the Caldwell and Finest NGC catalogues.

Light pollution is a serious problem for amateur astronomy here on the edge of Edinburgh, Scotland, so this is a battle of photons vs sodium! Please come back and visit as the site develops, I make lots of mistakes, the weather gets worse and the skies get brighter.

I am a member and webmaster of the Astronomical Society of Edinburgh and some of my pictures are displayed on their Flickr page.

NGC 2264 Christmas Tree Cluster narrowband

No more MPCC and stars are much sharper at the edges.

M42 for 2019 narrowband

29 January 2019|M31-60, Nebula, News|

This year in narrowband. Two attempts at colour mapping.
Need to get rid of the MPCC with this telescope as the image is better without. Too much star trailing with.

B33 Horsehead in narrowband

14 January 2019|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

6 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.
