This article is about exploring the world of light our eyes cannot see, using a modified digital SLR camera. I have a physics degree but I’m still finding my way with the practical applications of infrared and ultraviolet, so this article is mostly written from a theoretical point of view. Take everything I say with […]Read more "Full spectrum camera conversion"
After a successful first attempt with my new telescope, I decided to book a day off work, spent all night in Somerset and all day sleeping it off. I had lots of fun and I learnt an enormous amount – even if it did get quite chilly by 2am. I was paying more attention to […]Read more "More deep-sky astrophotography"
This morning I published a picture of the Andromeda galaxy, with some notes about my method a vow to improve my technique. I pondered the image processing and decided to have another go this afternoon. This is the same dataset, but different processing. It’s a colour image and unfortunately shows some light pollution, although I […]Read more "First light part 2"
Hot on the heels of my recent post about telescopes for imaging, in this post I’d like to share with you the very first image taken with my new GSO 6″ f/5 imaging Newtonian – which was funded by selling my two previous telescopes and a couple of camera lenses. Tonight was the first clear […]Read more "First light: GSO imaging Newtonian telescope"
Well, “perfect” is a strong word. No matter what you’ve got, there’s always something better. This article is about my hunt for some suitable equipment for deep-space astro-imaging, inspired by the recent purchase of a new telescope for imaging. Ideally I’d be out using it right now, but it’s forecast to be cloudy until further […]Read more "Finding the perfect astro imaging setup"
Some time ago I got a new telescope – a Celestron 130EQ-MD Newtonian rather than a Celestron NexStar 127 SLT Cassegrain-Maksutov formula. In short, it is more sensitive to light but sacrifices magnification. It’s perfect for deep-space observation like nebulae and galaxies, while the Maksutov is better for observing planets which are much brighter and […]Read more "Andromeda Galaxy"
Last night it was clear and there was no moon. I headed out with my telescope to see what I could see, and ended up photographing Messier 5, which is a globular cluster. This composite is made from about 100 images, each 3 seconds exposure with my Celestron NexStar 127 SLT and Canon EOS 600D, […]Read more "Messier 5"
