  1. With less sharpening. The image is limited by the pixelation though.
  2. Taken with 9.25 Celestron XLT and ZWO ASI1600 in RGB. Better than my last ! Doesn't really compare with some other images on here though :0).
  3. Probably, that was just the lowest I had used. I have not really used SharpCap much or experimented with changing the filed size ROI setting. There is always so much to do/learn!
  4. This is my first ever image of Mars. It was captured using SharpCap, with a ZWO1600M on a Celestron 9.25 XLT. I messed up quite a bit, ruining a lot of frames by have too dim a blue channel. )So, this is based on the poorest resolution camera settings, 800 x 600 pixels. 1000 frames per channel, at around 18 fps, best 25%) However, it is recognisably Mars, so I do have a degree of satisfaction, also I now have a target to improve against. The ice cap is clearly visible, as are dark and light areas . And its Red!
  5. The image is based on around 40 mins in each R, G, B and L, 118s subs, at a gain of 139. Calibrated with dark flats and flats. Wikipedia: NGC 40 (also known as the Bow-Tie Nebula and Caldwell 2) is a planetary nebula discovered by William Herschel on November 25, 1788, and is composed of hot gas around a dying star. The star has ejected its outer layer which has left behind a smaller, hot star with a temperature on the surface of about 50,000 degrees Celsius. Radiation from the star causes the shed outer layer to heat to about 10,000 degrees Celsius, and is about one light-year across. About 30,000 years from now, scientists theorize that NGC 40 will fade away, leaving only a white dwarf star approximately the size of Earth.
  6. Thank you, a pleasure on a warm summer night.
  7. A warm summers night, nicer outside than insdie a hot house. No nautical night, so I thought I would just browse the heavens, keeping a single frame as a souvenir of my tour. The colour image is based on single frames of L, R, G, B. Usual exposure length around 3 mins.

  8. I like the way you have handled the stars. It is something I need to really look at. I have tried imaging this but have ended up with stupendous stars spoiling it !
  9. This is based on 114s subs, around 60 mins in L,R, G and B. First time I have used the ZWO camera with the Skywatcher refractor. From looking at Xiga's image I can now see how deplorable my star sizing is ! Wikipedia:The Pelican Nebula (also known as IC 5070 and IC 5067[1]) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbour, the North America Nebula, by a molecular cloud filled with dark dust. The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain, and among these are found two jets emitted from the Herbig–Haro object 555. Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.

  10. I shall Hasta La Vista Green it ! There we go, you are right, a definite improvement!
  11. Subs of 114s, around an hour in each of L,R,G and B. Moon was around 4 days old and not a lot of astronomical night! Wikipedia: NGC 6946 (also known as the Fireworks Galaxy or Caldwell 12) is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs. Various unusual celestial objects have been observed within NGC 6964. This includes the so-called 'Red Ellipse' along one of the northern arms that looks like a super-bubble or very large supernova remnant, and which may have been formed by an open cluster containing massive stars. There are also two regions of unusual dark lanes of nebulosity, while within the spiral arms several regions appear devoid of stars and gaseous hydrogen, some spanning up to two kiloparsecs across. A third peculiar object, discovered in 1967, is now known as "Hodge's Complex". This was once thought to be a young supergiant cluster, but in 2017 it was conjectured to be an interacting dwarf galaxy superimposed on NGC 6964.

  12. I dont think so, it was green before I used a mask to try and 'enhance' it.
