And here is the famous Bahtinov mask to adjust the sharpness on your stars in astrophoto. This mask is very useful for everyone. Whether you are doing astrophoto with your DSLR, your telescope or your telescope, it is imperative to focus very precisely. What a beautiful invention! Thank you Mr. Bahtinov! Here is for you, happy owners of the superb Evostar 72ED astro bezel, this specially adapted mask. It sounds simple to do, but it took me some time to work out several details. The mask has 3 wings that will help to keep it in place despite a "little play" so that it can be put on and taken off very easily. I strongly advise you to: print it in black and, above all, not to put adhesion on it because the grid parts are the first to be printed and the adhesion cannot be easily removed. don't hesitate to use the "hairspray trick", it works like a charm ;O) To make it quick and easy, you will find the printing parameters below good heavens to all!
