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.

Need to get rid of the MPCC with this telescope as the image is better without. Too much star trailing with.

NGC 1514 Crystal Ball Nebula

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.

97.8% Moon – Copernicus, Kepler, Aristarchus and Sinus Iridium
Not much imaging recently because of terrible weather. This was the only chance and the seeing was incredibly bad after a rain storm. The Maria were undulating so much they looked like there really was water in them. Still got something though.

NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way’s Perseus Spiral Arm. This 20×30 arcmin sized nebulosity is also associated with open cluster IC 1590, several Bok globules and the multiple star, B 1. It collectively forms Sh2-184,[3] spanning over a larger area of 40 arcmin.[4] A recent distance from radio parallaxes of water masers at 22 GHz made during 2014 is estimated it lies 2.82±0.20 kpc. (9200 ly.) from us.[5] Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.
E. E. Barnard discovered this nebula in August 1883, who described it as “a large faint nebula, very diffuse.” Multiple star ‘B 1’ or β 1 was later discovered by S. W. Burnham, whose bright component is identified as the highly luminous O6 spectral class star, HD 5005 or HIP 4121. It consists of an 8th-magnitude primary with four companions at distances between 1.4 and 15.7 arcsec. There has been no appreciable change in this quintuple system since the first measures were made in 1875.

I did take some RGB colour but as you can see below there is a huge dust mark in it. Normally not a problem as flats will remove it. But when I went to create flats, the dust had disappeared so very difficult to remove. Unless it’s not dust but an out of focus reflection of the bright star? If it is I’ve never seen anything like it in my images before.
Bubble nebula project (NGC 7635)
One of my favourite objects. Trying to do this over a series of nights. Ha first of all then add colour channels. Only 2x300s exposures in Ha so far.

M40 (Winnecke 4)
Messier 40, also known as Winnecke 4. Basically it’s a double star, and an optical double at that!
It was discovered by Messier while he was looking for a nebula reported in the area by Johannes Hevelius. He couldn’t find it so he catalogued this double star instead. Most have been a slow night or something…
And why did I bother imaging it? Well it was in the only patch of clear sky there was and I only had a few minutes before it clouded over. Still, it’s another Messier object to add to my list 🙂
