I managed to shoot the Seagull nebula in the constellation Monoceros 5 times. Literally before the shooting, the weather deteriorated and the whole sky was overcast with clouds. Several trips out of town were wasted because of the clouds. On February 5, 2019, the weather still took pity on me and was able to fully capture this interesting area of ​​ionized hydrogen. Below and to the left of it is the Thor’s Helmet nebula in the constellation Canis Major, which got its name for its resemblance to the winged helmet of the Scandinavian thunder god. The departure was very successful, there were only a few clouds at the very beginning, while I set up the autoguider and searched for the nebula. There was wind, but the rocks were well protected from the it.

There were great difficulties due to red halos – the result of using a CLS filter with a modified Canon 550Da camera. When shooting without a CLS filter, they practically do not interfere, but due to the noticeable light pollution, I still had to use this accessory. The filter does not transmit light between the red and green ranges of the spectrum, which leads to a choice in focusing – either in the red channel or in the green. It is possible that using a more advanced L-Pro type filter will improve the situation. A compromise is possible – focusing between the red and green channels, but this will lead to a decrease in resolution. Perhaps next time I will try this kind of focus. The problem itself lies in the photo-lens – undematured chromatism and spherical aberration in the red channel.

The last Mars in this shooting season and in 2019 – the angular size of Mars is only 6.4 seconds of arc, and the distance to Earth is about 220 million kilometers (which is comparable to the distance from the Sun to Mars). The best conditions for observing Mars will be in the autumn of 2020.

Lunar eclipse. January 21, 2019, 06:37

On the morning of January 21, 2019, an interesting event occurred – a lunar eclipse. I had to get up early to get together and get to the open area. I decided to go to the sea, the sky is visible to the horizon. The weather let us down a little, fast clouds were moving in the side of the moon. Nevertheless, we managed to capture some of the phases (from 06:37 to 07:09 local time).
Equipment: Celestron Omni XLT 127, Sky-Watcher AZ3 mount, Canon 5D mk II camera. Location: Anapa, Vysokij bereg.
