Пацаны давно визуально этот пульсар наблюдают, без всяких EMCCD.
Цитата с 22 страницы руководства к Ситеху:
Here is a Challenging Idea. If you have or have access to, a very large aperture telescope, 28 inches or larger, you may be able to see the crab pulsar blink. Here's how. Obtain a servo motor with encoder that is able to run at least 1,800 RPM, you could connect this motor to a servo controller, and put an interrupter on the shaft of the motor (a circle with a pie shape cut out of it), balance the interrupter, and hold this assembly between the secondary mirror and the eyepiece, while running at somewhat less than 1800 RPM. You may be able to see the pulsar wink in and out! To test this out, you may use one of the LED's. It winks at the same frequency of the crab pulsar while in the equatorial mode! You can configure the equatorial mode to automatically run this motor at the proper speed.
Dan Gray reports that he tried this, and succeeded!!! His report follows:
“A group of about 8 of us were able to SEE the pulsar fade in and out using this approach! We were using the 61 inch Kuiper telescope near Tucson Arizona, so I dusted off my pulsar detector and took it along. It was fairly easy to see the pulsar in the 61", without using anything at all, but when the chopper was in, it was harder to detect. Even with the 61", it was challenging, but everyone that tried, was able to see it.”
Для отрицающих иноземную речь - сделали заслонку, закрутили ее с нужной частотой и влепили систему с окуляром в большой телескоп.
