My PixInsight Guide digital copy originally was going to be published free of charge to my fellow astrophotographers! as I have no interest in making money from this rewarding hobby and astrocaller.co.uk is all about helping those learning or those looking to improve their skills.

​However due to the devastating bushfires in Australia and the impact these fires are having on the wildlife especially the Koala's I Michael Caller have decided to charge a £10.00 fee for a digital copy (PDF) of My PixInsight Guide and donate all monies to the The Longleat Charity supporting three rescue centres in Australia that are hard at work recusing Koala's, Kangaroo's & Wombat's and proving them with the care they desperately need!
