Look for the brightest and biggest stars to align.Ħ. This will attach a mesh to the layer that you’re working on which is used to warp the image bit by bit to accurately align the stars manually.ĥ. Now, go to the Edit menu and select Puppet Warp. And the only thing that didn’t move between frames was the foreground, note how dark that area is.Ĥ. The number of stars has doubled because they are all in different places between frames. Where there is a difference it will appear brightly and where objects are perfectly aligned it will be black. This will show the difference between the two layers by using brightness. Select the top visible layer by left-clicking on it in the layer panel. Stack you exposures on top of each other in one window in Photoshop.Ģ. If we stacked and blended our layers without the stars being aligned, they would almost certainly be blended out of the image entirely.ġ. This removes the noise and sharpens the stars (if they are aligned). To remove this noise we stack our aligned images and blend them using a mean or median blending technique. STARTRAIL PHOTOSHOP PLUGIN ISOBecause the exposures are short we have to crank up the ISO which throws a lot of noise into our images. Shooting the stars at night without the use of a star tracker usually requires a lot of short exposures being taken to avoid star trails. The reason for needing to align the stars in post-processing is to prepare the layers for stacking. It is labour intensive but worth it in the end.Īlign Stars For Blending And Noise Removal. In the images I have chosen for this demonstration I tried every single auto method known in photoshop and none of them worked well enough. No matter how hard you try in Photoshop they will not align automatically. If your image is complex with a lot of stars in it you will have to manually align your exposures. When shooting with a wide-angle lens in particular objects further from the centre will be distorted more than object nearer the centre. Another major contributing factor to the need to manually align the stars is lens distortion or barrel distortion. And, because of the tilt of the earth in relation to the celestial equator the rotation of the star is only very rarely perfectly circular, it is more often elliptical. However, this isn’t possible, for the simple fact that the stars aren’t rotating on a flat X and Y-axis. So it almost seems logical to try to find the north celestial pole and simply rotate the individual exposures around the same fixed axis to align them. We know the stars rotate around the north celestial pole, very close to the North Star.
