Hello to the whole steemit community, today I come up with another interesting topic such as astrophotography, this art has its techniques so that we can capture celestial bodies at higher intensity, they will ask why in some pictures of astronomy pages you can see the most starry sky , of what our eyes can not perceive? the reason is that, you must follow some parameters to achieve excellent photos, it is through long exposure photography, which consists of having a DSLR camera, configure it and a tripod, an example of configuration that I use generally, with my Canon T3 camera, I go to the menu and I set exposure time between 20 "(seconds) to 30", then the ISO varies in the tastes of each professional photographer or in my case amateur, I place 800 0 1600 which are the basic parameters and they are recommended to avoid electronic noise, there are others that use higher ISOS, (the ISO is the sensitivity of the sensor to capture the light of the stars or other celestial bodies), then I place temporizado of 2 "to not have to do it manual and I have the risk that the photograph I run, have to be very careful where they are since the wind can knock down the tripod, it is advisable to place a counter weight, an improvised and simple the way, is to place some rocks or weights inside a thick plastic bag so when you take the picture do not move them.
I will show you two simple examples that I made:
I offer an apology for not being able to explain these techniques to you in more detail, due to the electrical problems that we have in a large part of the country and especially in the city that I live, believe me that many of us who live in Venezuela do miracles to achieve publication, I hope that this will help a lot to those who want to start in astrophotography and I recommend 1000% is an art that should be spent a lot of time, but have amazing results, until the next delivery.
