Прошу помощи не только в грамотном переводе,но и в изготовлении аподизирующей маски для 12" Доба.На клаудях дали совет:
"Apodizing masks are actually very easy to make. I made a prototype out of regular box cardboard (brown, color does not matter in the dark!) for my 20" dob. It worked so well i never made another out of better material but i added tape around the edges to make it last.If you have a particular f-ratio on mind, you will already know the size of hole to cut based on your focal length.The only trick, and this is really not a requirement, is to make the center of the holes at the point between the secondary ed ge and primary edge. so if you have a 2" secondary and a 12" mirror, the hole center should be hallway between 1" and 6" from the center, which is 3.5" from the center. They do not need to be exactly 120 degrees apart, a good approximation is just fine.i used 3 holes (5" diameter) but you could easily cover 2 holes for different uses, particularly bright objects. You might try 3" holes. Its all rough and is not very particular to exactness to work really well.Hope this helps, give it a go you'll be surprised how easy it is."
Сам не сделаю точно.Нужность/ненужность этого устройства для меня не вопрос.Хочу попробовать.
