The Astronomy Tools Actions Set for Adobe Photoshop® gives you the following 34 functions, each of which you can invoke with a keystroke or mouse click. If you want to polish up your astrophotographs to be absolutely stellar, these actions are for you! They work great with Adobe Photoshop® versions 6.0, CS to CS6, CC, 2020 and newer on PCs and Macintoshes alike, and come with a money-back guarantee. I put a lot of time into getting them to work just right and to combine well with other actions and operations. These are professional quality actions - macro operation sequences that you load into Adobe Photoshop® - producing top quality results you can print or use in further Adobe Photoshop® operations. What do the actions in Astronomy Tools actually do? I've put together a great set of actions that deliver top quality results and can save you a bunch of time! Noel Carboniīeginners: Ever shoot your own images of the night sky, then find yourself wondering how other astrophotographers make such breathtaking images while yours don't seem to have quite the same sparkle or magic? Chances are they do more digital editing of their images than you think.Įxperts: These actions give you access to top-notch look and feel results otherwise difficult and time consuming to achieve. While some good tools were available, there were simply some functions for which there were no easy solutions, and still others that I simply found myself doing over and over again in Adobe Photoshop®. You can also in post erase the diffraction spike.As I progressed into astrophotography, I discovered that a great deal of digital image processing can be needed to get the best out of one's astrophotos. This can also work if the diffraction spike is interfering with the object you are trying to image. If you have a reflector telescope or using Fastar/ Hyperstar, you can minimize diffraction spikes by taking multiple images while changing the angle of your telescope and then overlay the images. If you want additional diffraction spikes in your reflector or Schmidt Cassegrain, lay string across the optical tube. In addition, when you use astroimage cameras, you have cables going in and out of the camera that go across your optical lens preventing light from coming in and creating a diffraction spike. If your DSLR is bulky and is bigger than the secondary mirror, it blocks light coming into your mirrors and therefore creates a diffraction spike in your image. You can manually create diffraction spikes when using Fastar/ Hyperstar with either your equipment (bulky cameras or Astroimaging cameras) or with strings you place on the front part of your optical tube. With the secondary mirror being held up by the lens it eliminates diffraction spikes. This spike isn’t present with refractors as it doesn’t have a secondary mirror.Ĭelestron Schmidt Cassegrain and EdgeHD optical tubes have an optical lens at the front-end where the secondary mirror is held in the middle. A diffraction spike is caused by how light bends or diffracts around an object or in this case the support beams in your secondary mirror in reflecting telescopes. A diffraction spike is the light you see extend from a star in your astro-images.
