Over 10 years ago I selected most of the most colourful stars in the sky visible with a 30cm telescope. There are ab...

Thank you for pointing it out to me

Dear Ann, thank you :) The stars I have selected for the Ghirigori are those that show the highest colour contrast in visual observation. That is why they are often doubles or tris of perspective stars. I have not selected stars solely on the basis of the B-V index also because bright stars, particu...
