    Messier 8

    The Lagoon Nebula is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and a H II region. The Nebula is estimated to be between 4,000-6,000 light-years from the Earth, the age is about 2 million years old and its size is around 110 by 50 light years. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), also the nebula is currently undergoing a period of active star formation and has already formed a sizable cluster of stars. NGC 6530, the extremely young open cluster formed from the material of M8, has a visual magnitude of 4.6 and covers an area of 14 arc minutes in the sky. I have uploaded 2 versions. One shows more contrast while the other shows more of a natural colour.

    NGC 6164/5

    Thanks for the responses guys. Yeah this object is a southern Hemisphere object. Trying to get the outer shell was the most difficult to get. As I'm limited to around 10min on my mount that is the best I can do until I can upgrade.

    NGC 6164/5

    NGC 6164 NGC 6164 was created by a rare, hot, luminous O-type star, some 40 times as massive as the Sun, the cenetal star is about 3 to 4 million years old. In another three to four million years the massive star will end its life in a supernova explosion. Spanning around 4 light-years, the nebula itself has a bipolar symmetry. NGC 6164 has been found to have an extensive, faint halo, expanding into the surrounding interstellar medium, the material in the halo is likely from an earlier active phase of the O star.

    M 20 GSO RC 6

    Messier 20 The Trifid Nebula (M 20), is an Ha region located in Sagittarius. The name means divided into three lobes, the object is an unusual combination of an open cluster of stars; an emission nebula (the red portion), a reflection nebula (Blue portion and a dark nebula.

    Shapley 1 ZWO ASI 1600mm

    Shapley 1 is an annular planetary nebula in the constellation of Norma with a magnitude of +12.6. As viewed from Earth it is a torus shaped planetary nebula. It is approximately 4900 light years from Earth, and is around 8700 years old. At the center of the nebula is a magnitude 14 white dwarf star. Its about .32 light yrs across.

    NGC 4945 ZWO ASI 071 Pro

    I live in dark area so I can get maximum dynamic range but the trade off is higher read noise. But as for a starting point. Unity gain is fine, but it comes down to how close you live to a city or town. If you live to close your images will be washed out at 5min lights. Have a look at this. https://www.cloudynights.com/topic/590093-suggested-sub-exposure-tables-for-asi071mc-c-and-qhy168c/

    47 Tuc ZWO ASI 1600mm

    47 tuc is a globular cluster located in the constellation Tucana. It is about 13,000 light years away from Earth, and 120 light years across. 47 Tuc can be seen with the naked eye, with an apparent magnitude of 4.1, due to its far southern location, 18° from the south celestial pole, it was not cataloged by European astronomers until the 1750s. 47 Tucanae is the second brightest globular cluster after Omega Centauri, and it is one of the most massive globular clusters in the Galaxy, containing millions of stars. 47 tuc may contain a blackhole at the center.

    NGC 6188 ZWO ASI 1600mm

    Hi Adam im still getting the feel of the 1600mm, but so far I’m really happy with it. I found that the 071 is good for bright DSO objects and if you want a quick image. I moved to mono so I can really start to bring out as much detail as possible and start to image in NB. At a later time I want to get into doing Hubble platte , but since a started to image HA I realised I’m missing out on a lot of detail.

    NGC 6188 ZWO ASI 1600mm

    NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, is visible to the naked eye is responsible for a region of reflection nebulosity within NGC 6188. The emission nebula is found near the edge of a large molecular cloud unseen at visible wavelengths. First image doing a complete RGB and Narrowband image.

    NGC 4755 ZWO ASI 1600mm

    Hi Not without some serious editing. As my scope has spider vines all bright stars will have spikes. I would need to get a SCT or refractor to remove the spikes without damaging the picture.

    NGC 4755 ZWO ASI 1600mm

    The Jewel Box, is an open cluster in the constellation Crux (the southern Cross). This cluster is one of the youngest known, with an estimated age of 14 million years. It has a total integrated magnitude of 4.2, its about 6,440 light years from Earth, and contains just over 100 stars. The cluster has many blue type stars but has 1 red supergiant star, with is about 600x bigger than out sun. First object using my new mono camera!!!!

  13. First attempt at jupiter using my GSO RC 6 with a 2.5x barlow and filter wheel. LRGB combined to about 800 frames. Learnt how to use PIPP, Registax and winjupos.

    NGC 4038 ZWO ASI 071 Pro

    NGC 4038 The Antennae Galaxies, also known as NGC 4038/NGC 4039, are a pair of interacting galaxies in the constellation Corvus. They are currently going through a starburst phase, in which the collision of clouds of gas and dust, with entangled magnetic fields, causes rapid star formation. The Antennae Galaxies are undergoing a galactic collision, these two galaxies are known as the Antennae Galaxies because the two long tails of stars, gas and dust ejected from the galaxies as a result of the collision resemble an insect's antennae. The nuclei of the two galaxies are joining to become one giant galaxy. Most galaxies probably undergo at least one significant collision in their lifetimes. This is likely the future of our Milky Way when it collides with the Andromeda Galaxy in a few billion years. Located only 45 million light-years away. Image was taken near a bright moon so some signal noise was introduced. GSO RC 6 ZWO ASI 071 Pro HEQ5 belt mod 10min x 20 = 3.3 hr
