About Me

My photo
A retired Welshman living in wonderful Plymouth in SW England, I’m a family man, novice sailor and boat builder, astrophotographer and motorhomer. With a passion for all things to do with education and the sea and skies above, I have a sense of adventure and innate curiosity. I write three blogs. ‘Arwen’s Meanderings’ charts my learning to sail a self-built John Welsford designed ‘Navigator’ yawl. Look out for her accompanying YouTube channel www.YouTube.com/c/plymouthwelshboy . ‘UnderSouthWestSkies’ follows my learning journey as I take up astronomy and astrophotography; a blog for beginner’s new to these hobbies, just like me. ‘Wherenexthun’, a co-written blog with my wife Maggie, shares how we ‘newbies’ get to grips with owning ‘Bryony’ an ‘Autosleeper’s Broadway EB’ motorhome, and explores our adventures traveling the UK and other parts of Europe. Come participate in one or more of our blogs. Drop us a comment, pass on a tip, share a photo. I look forward to meeting you. Take care now and have fun. Steve (and Maggie)

"This last week or so I have been chasing Comet Tsuchinstan-ATLAS. It has been playing 'peek-a-boo' between the scuttling clouds. Never taken photographs of a comet before, so its been a steep learning curve"

 I remember the evening well. There were many people gathered at Wembury beach car park all looking for the elusive comet. Many had never done stargazing before. Armed with an eclectic mix of binoculars all eyes were turned to the south west horizon just as sunset descended. 

After some research on various facebook astrophotography forums, I had selected the following equipment for the night: 

  • Canon 800D
  • Samyang 135mm (or 14mm lens as I did interchange lenses during the session)
  • Canon 50mm lens
  • intervalometer
  • Benro carbon fibre tripod 
I processed the results in SIRIL and affinity photo. First time I have captured a comet. 

Love the sky colors - sadly I am not sure they are representative of nature but rather of my poor post editing skills. Blue, I am reliably informed on Facebook, is not a natural colour in space! 



I think these final images were a better effort at processing. 
It is all the same data gathered on the night just post edit processed slightly differently 



These images were processed in the program Sequator 


Finally two images which are reasonable
