Astrophotography is a series of techniques that implies many skills (DIY, hardware, software, equipment, processing knowledge…) and also lots of patience to give room to yourself to improve your images year by year.

My trip into astrophotography has allowed me to start as a beginner using a second hand DSLR and a newtonian telescope. Many months of practice made room to invest in a new mount, camera and telescope. As the time went by I also did a longtime learning in the processing techniques.

This image comparison is a good sample on how, under the same sky (Bortle 3/4) you can get really different results according to new equipment and processing experience.

This exercise aims to motivate the newcomers to acquire their own images, from their backyards or their dark sky favourite places. In my opinion, the image you create from 0 is the best prize for all your effort. No matter the quality of the result, it is your own deep sky image. I wish you all good luck and clear skies.

Once purchased, you have 24 hours to download the photo. You will receive an email with the download link.

Support my work. If you want to help me continue with my work, please feel free to buy, just for a few pennies, one or several of my images. The price does not reflect the amount of effort involved in each one of the images. Some of them implied weeks, months and even years of hard work. With your purchase I will be able to continue capturing photons of our amazing universe.
