Forthimage: 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. I also contribute data to the HOYS citizen science project, ExoClock and the BAA Mars section.

KELT-2Ab

18 February 2021|Exoplanet, News|

First results using CMOS camera. Was an ExoClock ALERT.
A difficult and very large dataset (33 Gb). Results are inconclusive and need verification.
Helped debug HOPS v3.0 during the process.

M42 Ha with Telescope Live in Chile CHI-1

8 February 2021|M31-60, Nebula, News, Robotic Telescope, TelescopeLive|

Free trial of Telescope Live using one-click imaging (basically piggybacking onto other observations). It’s really not the same as doing it yourself, with your own equipment, from you own garden, with all the challenges. But when the weather is dire – it’s fun! Advanced, full control of the telescopes costs A LOT more. though!
