There are many astro stacking programs to choose from. ![]() In this article, we will discuss some of the most popular software available for astrophotography image stacking. Image stacking is the technique used to improve the signal to noise ratio, and it is the only noise reduction method that will boost the image details rather than smear them out. Reduce noise and deal with light gradients and vignetting.In astrophotography you cannot avoid post processing your images, so stacking and editing your images serves three main purposes: We’ll be having a great time in the darkest hours of the night.Astrophotography is closer to science than art, and there is no such thing as “getting it right in camera.” This means you cannot simply point the camera at the sky and snap away. It’s a present from our guests, to us and to our guests. Starry sky in real timeīefore long, you’ll be able to view the starry sky above Monte do Casarão through a real telescope: the Sky-Watcher Skyliner-300P Flex Tube 30 12 inch Dobson. the Lagoon Nebula and Trifid nebula at your leisure, enjoying beautiful structures in the Milky Way. On Monte do Casarão these constellations rise well above the horizon (in the evenings during the summer or at night in the spring) so that you can make the most of the stunning objects: through binoculars you can look out for e.g. In Western Europe this area may just rise above the horizon during the summer and then usually drowns in the light soup of the nearest town of village. In Portugal, the spectacular globular cluster of Omega Centauri can just be glimpsed above the horizon.Īnother example is the environment of the constellations of Scorpius and Sagittarius: the most beautiful parts of the Milky Way. One example is the Centaurus constellation, featuring many beautiful nebulas and stars. The vast advantage for stargazers (astronomers) is that objects that in Britain tend to remain hidden behind the horizon actually become visible here. At night, all stars are 15 degrees higher as well and for that reason, they are easier to see. In daytime, you can tell by the sun, which is 15 degrees higher and yields more heat. Southern Portugal lies 15 degrees further south than London. For those in the know: an SQM value of 21.7 is quite ordinary here. You can tell with the naked eye, with binoculars and with a real telescope. Moreover, the Alentejo climate provides a dry transparent sky that helps you see far more stars, nebulas and constellations than elsewhere. In Britain, you’ll have to travel far north to find a place where it’s this dark. And it goes for the experience observer who is looking for pale nebulas with the aid of a telescope and a detailed atlas and tries to recognize the tiniest details by gazing at them for the longest time. That goes for the beginner who is trying to recognize constellations and waiting for shooting stars from his deck chair. To enjoy stargazing, you really need to take your time. Firstly, this is due to the rest and relaxation a holiday brings on. Monte do Casarão is eminently suitable for enjoying the starry sky. You can find more pictures taken by him (and by fellow-astrophotographers) on the (German-language) website Tom Zalmstra’s starry sky We are allowed to use the pictures he has taken. The camera Jacobs used is an FLI ML 16803, with a Mamiya long-focus lens 645 300mm 1:5,6. The photos have been taken with an RGB and an H-alpha filter with a two-hour exposition time. He photographed both the Orion’s Belt (M 78) with the Horsehead Nebula and parts of Barnards Loop as well as the Rosette Nebula (NGC 2244) and the Christmas Tree Cluster (NGC 2264) in the Monoceros constellation. He was at least as happy with the pictures he took on Monte do Casarão and with the circumstances here. Normally, Carsten Jacobs travels to Namibia to take pictures of the stars at the International Amateur Observatory. Astrophotographer Carsten Jacobs and amateur-astronomer Tom Zalmstra were here and they are happy to share their experiences. According to connoisseurs, Monte do Casarão is such a place. If you want to enjoy the starry sky to the full, you’ll have to find a place that shows stars in full splendour. In most parts of Europe – as well as vast parts of Britain – fewer and fewer stars can be seen as a result of light pollution and smog.
