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.

2MASS J21383981+5708470 in IC1396A

28 June 2019|HOYS-CAPS, News|

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

25 June 2019|Jupiter, News|

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

1 April 2019|Caldwell, Galaxy, News|

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.

After a HOYS-CAPS session added narrowband. Rat’s head in there?
No more MPCC and stars are much sharper at the edges.
