Author and astronomer Ron Wodaski has generously provided his book The New Astro Zone System for Astro Imaging free to teachers and students using SPIRIT.
The ‘Zone System’ provides invaluable information for getting the most out of your astro images using Adobe Photoshop, and is particularly useful to teachers and students who have attended the SPIRIT 103 workshop at SPICE.
Authorised teachers and students can download a PDF copy of the book here.
A password to unlock the file can be obtained by contacting us.
Additional support materials and tutorial images can be downloaded free from the Tzec Maun web site.
