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.

Wizard Nebula HOO NGC 7380
After doing HOYS-CAPS data on a very murky, moonlit night, decided to try narrowband on this.

Pelican Nebula HaRGB IC 5070
A by-product of doing HOYS-CAPS data for V1490Cyg in HaRGB, decided to make a colour image out of it even though only 3 subs for each filter.

Wide angle Milky Way shots from the Languedoc
So – because there’s no night in Scotland from May to August, I went south to the Languedoc hills. Sainte-Polycarpe in the Aude region to be precise. First real use of my Skywatcher Star Adventurer mount. Great fun, still a lot to learn, but got some decent images. Also made a fun little video story of my holiday in a beautiful region of France.
Cygnus Wall – red channel only
After gathering HOYS-CAPS data thought I’d give this a quick go in red channel only.

2MASS J21383981+5708470 in IC1396A
Been gathering HOYS-CAPS data on 2MASS J21383981+5708470 in IC1396A recently because of a possible increase in brightness. This has been stretched and processed to show details. Normal submitted data wouldn’t be.

Jupiter colour / infrared
Jupiter is so low that only half of the telescope could see over the lip of the dome, so effectively only a 125mm telescope – not 250mm! Surprised I got anything at all at this altitude.
Not much detail visible but the infrared version is much sharper, cutting through the atmospheric turbulence better, and shows the Great Red Spot as white. The SEB is clearly changing and shows white in the colour image. Is this part of the unravelling of the GRS that is reportedly happening?

NGC4565 / Caldwell 38 Spindle Galaxy
Processed 3 different ways – give different results, not sure which I like best. Still too noisy – need many more exposures.
Interesting edge-on spiral galaxy in Coma Berenices, surprisingly large (14.9′ x 2′) but faint (9.60 but surface brightness 13.3). It is actually intrinsically more luminous than the Andromeda Galaxy. First seen by William Herschel in 1785. Also visible lower right is NGC 4562.
