Previous picture of Veil nebula was done by using focal length 1000 mm. Since this nebula is huge, I wanted to capture also the other parts. This time I reduced the focal length to 730 mm, by ASA corrector/reducer.
M13 Great globular cluster in Hercules
Great globular cluster in Hercules is huge, it contains approximately 300 000 stars and it has about 145 light years in diameter and it is 25 thousands of light years away from the solar system. In 1974 a message from Earth was sent to M13 inhabitants, but due to the speed of light will be received after 24,959 years (Arecibo message).
