Moon – Waxing Crescent

After long period of bad weather, I had the opportunity to take the telescope out and enjoy the clear skies. In the early evening, waxing crescent was setting down, so I took the opportunity and pointed my newton on the Moon. The illumination was only 34%, which means that as soon it gets dark, the Moon is not far from horizon and you have to capture it through thick layer of turbulent atmosphere. The picture is a stack of 700 frames.

Moon – closer encounter

Well, as I wrote before, I hate Moon. It is a big bright monster, polluting the skies by the light. However it has its beauties. For instance the terminator – the transition between bright and dark side of the Moon can show some interesting shadows of the craters. The Moon is relatively easy to photograph, one just have to have a long focal length and any camera. The pictures were taken by my new scope Celestron EdgeHD C14 with “guiding” camera ZWO 174 MM. Each picture is a stack of approximately 1000 frames, done in AutoStakkert and sharpened further in RegiStax.conv_Moon_180316_Gain=180_Exposure=1_regi02_FS conv_Moon_180316_Gain=180_Exposure=2_1ms_regi_FS conv_Moon_180316_Gain196_Exposure2_7ms_regi_fs conv_Moon_Gain196_Ex2_FS conv_MoonGain188_Exposure2_2ms_regi_FS


Moon, der Mond, la Lune, la Luna, Měsíc, Луна, Φεγγάρι. All these names belong to our closest natural satellite. The distance between the Earth and the Moon changes approximately from 350 to 407 thousand km. If there would be a highway to moon and you would travel by car 130 km/h, it would take approximately 112 days to get there.

The Moon is the easiest object on the skies to photograph, not including the Sun and the clouds. It’s very bright object, therefore doesn’t require long exposure times. Honestly I hate the Moon, because it’s egoistic object, because if it shines, you can take a picture of the Moon only. All DSOs are blended, due to very bright background. Only one thing is possible to photograph when the Moon is shining – narrow band imaging of higher wavelengths just like H alpha or SII, because these wavelengths are in red region and therefore are not affected by blueish color of the background.
