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.

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.

C5 The Hidden Galaxy

14 April 2021|Caldwell, Galaxy, News|

Another  go a this for the ASE Caldwell Project. A really tricky one this. Hidden in the dust from our own galaxy, this would actually be naked eye brightness if not obscured. From two sets of data but still challenging.

C4 NGC7023 Iris Nebula

14 April 2021|Caldwell, Nebula, News|

Another  for the ASE Caldwell Project. Horrible gradient to deal with but background is messed around with to bring out all the dust around it. Makes the rest of the background messy though.

IC 1848 Soul Music

6 April 2021|Narrowband, Nebula, News, NGC Autumn|

Well the Soul Nebula Mosaic anyway. 5 panes in the end. First 4 panes (see below)  should have done it but I suspect platesolving failed and I had to do another pane the next night. APP is brilliant at stitching together and blending in panes – even from different sessions.

C5 IC 342 Hidden Galaxy

Another tricky one. Needs to be much deeper and more subs.

M51 Whirlpool Galaxy

Didn’t expect to get too much out of this because of the high wispy cloud and only got 9 subs, but not too bad.
