also known as the Seven Sisters and Messier 45, are an open star
cluster containing middle-aged, hot B-type stars located in the
constellation of Taurus. It is among the
star clusters nearest Earth and is the cluster most obvious to the
naked eye in the night sky.
The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.
Object is located in the Monoceros constellation and are located about 800 parsecs or 2,600 light-years from Earth. NGC 2264 is the location where the Cone Nebula, the Stellar Snowflake Cluster and the Christmas Tree Cluster have formed in this emission nebula. For reference, the Stellar Snowflake Cluster is located 2,700 light years away in the constellation Monoceros. The Monoceros constellation is not typically visible by the naked eye due to its lack of colossal stars.
Unfortunately, the source photos contain a lot of noise. Probably all because of the unusual ISO that I set in the camera and other option that has been turned on. I’ve been experimented and realized that the settings I had on the camera definitely sucked. Today I think that I know, what is the key steps to taking good photos on my Canon.

M42 – Great Nebula in Orion – Also known as NGC 1976. This is the brightest nebula on the sky. It is located in the Orion constellation, south direction from Orion belt. The diameter of the nebula is 30 light years. The distance from Earth is 1344 thousand light years.
With this photo, I’ve tested my Mgen II Lacerta autoguider and in my opinion it did a very good job.

is a face-on spiral galaxy distanced 21 million light-years (six megaparsecs) away from Earth in the constellation Ursa Major. M101 is a large galaxy, with a diameter of 170,000 light-years. By comparison, the Milky Way has a diameter of 100,000 light years. It has around a trillion stars, twice the number in the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small central bulge of about 3 billion solar masses.
A good example showing how a coma mirror can break a nice picture. I’ve hope, that the coma corrector I will buy in the coming week, will eliminate the above mentioned optical defect in the entire camera frame.
