Forthimage – Amateur Astronomy from Edinburgh

This website is an observing log and a place where I can post my images and observations. You can find more information about the equipment I use on the About/Equipment page and Papers I am co-author of.

Having imaged many of the obvious objects I find it more satisfying now to contribute data to various projects.

I stand with UkraineI am currently President and Webmaster of the Astronomical Society of Edinburgh and some of my pictures are displayed on their Flickr page.

I contribute data to the HOYS citizen science project, ExoClock, BAA Mars, Solar and VSS sections, AAVSO, GOSA, GMN, UKMON, as well as others. You can now see my meteor camera data on the Meteor Camera page.
