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.

The Orion Nebula, March 13, 2020

Equipment:
-telescope Celestron Omni XLT 127
-reducer Antares f\6.3
-filter Optolong L-eNhance 1.25″
-camera ZWO ASI 183MC
-mount Sky-Watcher AZ-GTi
Location: Russia, Anapa, backyard
Stacking 521 frames per 1 second with Fitswork, wavelets with Registax 6.

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).

NGC 281 Pac-Man nebula. December 2, 2019

This is the first more or less adequate result with the Optolong L-eNhance 1.25 “filter. The filter cuts off most of the city light pollution, but at the same time passes the H-alpha, OIII and H-beta lines. Ghosting appears around bright stars, but personally they don’t bother me, I will continue testing the filter.

It is interesting to compare the result with another picture taken about a year ago with a monochrome camera QHY5III178m and a 12 nm H-alpha filter:
