If you had contacted us you would have found us receptive and grateful.
Before we pick it apart let's remember how Astronomy Tools came into the world: In 2014 Grant offered to build a set of tools for our colleagues working on FLO's Helpdesk. We wanted them to have easy access to reliable information, rather than using various separate online tools. The project also enabled us to develop and improve some of those tools. When built we decided to make 'Astronomy Tools' publicly available so everyone could use it. Free of charge.
Regarding the Astronomy Tools CCD Suitability Calculator: In 2014 (nearly eight years ago!) the guidance available to us was more basic than it is today. Much of the information included was based on lookup tables provided by leading camera manufacturers. The explanatory text was largely written for us by a prominent astrophotographer. I won't mention his name because he is a respected forum member and it isn't his fault we haven't updated his text with the new thinking and information available today.
When launched, Astronomy Tools was heavily scrutinised both on and off SGL then edited until it properly represented the best knowledge and information available at that time. But telescopes, cameras and best practices have evolved. Of course it needs updating. We should have done it sooner but it never seemed to rise far enough up the todo list. Today we are a larger company with more resources and the pandemic is easing so I am confident we soon will. When we do, it will continue to be available free of charge.
HTH,
