For instance, with FF camera and 24 mm lens ~15 seconds is maximum time exposure. Trees will be blurred and then it will be much more difficult to use masks in GIMP/Photoshop. A compromise - smooth horizon without trees and other standing out objects. The less landscape in the frame, the easier it is to work for IRIS. IRIS is developed for stacking telescopic images, thatвЂ™s why it can behave strangely when both landscape and sky are present in the frame. Built-in noise reduction will extinguish not only noise but also faint stars.

WeвЂ™ll reduce noise much better then camera can do it with a single frame. Shoot in RAW, all camera built-in noise reduction functions must be OFF. IвЂ™d like to emphasize: the choice of location is much more important than the price of your camera. The further from the cities and the higher to the mountains you are - the less the light pollution is and the less atmosphere is above you. With a typical suburban sky IвЂ™d not be able to obtain such a nice result. Milky Way was easily visible with the naked eye. The photo В«Crimean wayВ» is obtained from the very good place - Crimean Astrophysical Observatory (CrAO). Lots of dust above your head block the light from the faint stars. The sky itself is too bright, because it reflects cityвЂ™s illumination. In the cities or close it is useless to shoot the stars. The most important: sky should be really good. Try to make the best of the single image and compare it with the result after stacking the images.

Single-to-noise enhancement is a fundamental task for astronomers, and similar techniques is being used to process images from all the professional observatories in the world. ThatвЂ™s why the signal of the star after stacking will increase and the noise will decrease. On the contrary, any star always stays in the same position (of course, after registering pictures to take the EarthвЂ™s rotation into account). That means that the certain pixel in one frame is highlighted with the noise and in the other frame it isnвЂ™t. Digital noise on your CCD/CMOS basically is a random signal. And that is from where the main idea of stacking images stems. ItвЂ™s not surprising: when you reduce noise for the single frame, computer cannot distinguish between the noise and the faint star.

The difference in faint details is just tremendous. I am sorry but IвЂ™m too lazy to redo the animation. In the animation I compare two frames: one obtained with 15 stacked frames, and the other is just one frame, processed in LightRoom.ДЎ5 РєР°РґСЂРѕРІ means 15 frames 1 РєР°РґСЂ means 1 frame. The reason why do people stack images is demonstrated by the following animation.

I decided to write this a post after I got the following picture (click and hit F button for bigger size):Д¬anon 6D + Canon 24mm f/1.4L II ISO 16000 15 frames Г— 15 sec darks, offsets. What you will do: choose the place with excellent starry sky shoot 30вЂ“50 frames with right parameters register and stack frames in free software IRIS complete in photo editor like Photoshop or GIMP. Higly recommended to have: remote control (I use wired PiXeL TC-252 N3 with Canon 6D) or smartphone application for remote control. Necessary equipment: camera, shooting in Raw lens tripod computer with Windows OS.

Probably it is not the best idea to start learning how to shoot night photos with this post first try something less complicated. For those who have already tried night photography, who have been charmed by the night photography and crave more. The post is for: photographers who is familiar with RAW, who knows how to use masks in GIMP or Photoshop. Astronomers who shoot the sky do not face this problem, hence usually people donвЂ™t talk about it.

Wide-field astrophotography has its own features: rotating sky and motionless landscape are present in the frame. This post aims to teach how to apply the power of image stacking and noise reduction to a landscape astrophotography with ordinary DSLR. As a rule, stacking is not described in such manuals.

Lots of manuals on landscape astrophoto with usual DSLR and usual lenses. Why do people stack lots of frames to obtain only one final picture? First of all, in order to reduce the digital noise. Lots of manuals are available on registering and stacking telescopic images. Landscape astrophotography with IRIS Introduction
