The Orion Nebula, March 13, 2020

Orion is still available for observation in the evenings. I decided to shoot the Orion Nebula with second shutter speeds with 127 mm Schmidt-Cassegrain. In total, 1200 frames turned out, of which I manually selected the 521 best frame and stacked it. The capturing was carried out on an azimuthal mount Sky-Watcher AZ-GTi, field rotation compensation occurred when two stars were stacked to Fitswork.

I also made bicolor, replacing the blue channel with green. Nevertheless, I like the original RGB version more, because the blue channel (H-beta) is still different from red (h-alpha) and green (O-III).

    Здравствуйте, Руслан! Присматриваюсь к ШК Celestron Omni XLT 127 на EQ3. Подойдет ли данный сетап, дополненный моторами, гидом и редуктором фукуса, для постижения начал планетно-дипскайной астрофотографии?

    1. Здравствуйте. Да, вполне – универсальный сетап с хорошей устойчивостью. Только учтите, что с зеркальной камерой и редуктором будет заметное виньетирование (затемнение края). С небольшими матрицами (вплоть до 4/3) проблем не будет.
