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 currently President 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.

C3 NGC 4236

14 April 2021|Caldwell, Galaxy, News|

Added more data to this one but still very tricky. More horrible gradients to deal with. The IDAS P2 LP filter is no longer doing it’s job with the change in LP sources round here. Have now bought the IDAS D3 to see if that is any better as it deals more with LED lighting.
