My First Trip with Remote Imaging

astronomical image processing tutorials



A new Web-based documentation has been made and will be more up-to-date than this one. This new documentation also exists in PDF format for offline viewing. This was the main documentation page for Siril , a free software for astronomy image processing. It contains several video tutorials and links to other pages that contains pictures or videos. Many features are documented by a video. The processing workflows for deep-sky and planetary are documented as a series of pictures with text or as a film in the complete sequence processing section. A Display Mode viewer is used to improve the visibility of an image, but without altering its pixel data in any way, similarly to what DS9 scale does.

I have been working with Terry for about 5 months now and I am very happy with my progress so far. The tutorial includes one-on-one remote sessions using Screen Connect that are limited to a maximum of one 1. Can be purchased by selecting "Buy Now" or recurring monthly by using the subscribe button. Let me just start this by saying that finding Terry was a happy accident. Nobody introduced us, I just saw his Facebook page, looked around, liked what I saw and decided to contact him.

I got into astrophotography at the same time I got into observational astronomy: July , when I was given my first telescopewhile I was in graduate school. It was a fairly difficult place to start astrophotography, but I picked it up quickly, and have since been given or sold at a good discount even better equipment and cameras. It has been a fun adventure learning the hobby over the last three years! Recently, an awesome new opportunity walked my way: the chance to image on a high-caliber rig under the very dark New Mexico skies, from afar. When I was at the Texas Star Party, I met some folks from The Astro Imaging Channel, an online video series about astrophotography, who were going around interviewing people with astrophotography rigs and asking about their setups for a video they were putting together. They asked if I would do a presentation on their weekly show, and I had a great time presenting "Astrophotography Joyride: A Newbie's Perspective" which can be found on YouTube. I stayed on as a panel member for the channel and have gotten to know the other members.

Solar Image Processing - Full Disk This is an eight chapter tutorial using some of my methods for processing Solar images. Using Masks you will be able to blend images together as well as colorize the monochromatic based on brightness values. This will also demonstrate how to use HDR Toning and other filters to make your solar images more dramatic. You will need Photoshop CS5 or later to be able to take full advantage of the processes. Astrophotography processing tutorials and presentations by Ken Crawford. I believe that part of the fun of this hobby is the free exchange of knowledge between astrophotography enthusiasts.

Digital Image Processing

Astrophotography is an exhilarating pastime. Thanks to the digital revolution in amateur astronomy, taking deep space images is less of the almost overwhelming challenge it was just a handful of years ago. Today, with a modest telescope and digital camera, thousands of enthusiasts are producing beautiful images of galaxies and nebulas. However, one final hurdle persists- raw images produced through a telescope still require significant enhancement to bring out the secrets hidden within them. This can be a daunting procedure because processing astrophotographs has been, and remains, an essentially self-taught art. However, several imaging experts who have been honing their processing skills for many years have recently begun to reveal their hard learned techniques through books and, in , with DVD tutorials. This article is the second in a series that reviews the most recent and effective training resources for creating highly polished astronomical pictures.

Click each picture to see the full-size version. Dark Frame The first step is to create a dark image that will be subtracted from each frame of the real image. This assumes you captured some dark frames at the time you were capturing the original frames. If you didn't then skip this step and move on to step two. A Dark Frame is captured with the camera lens or telescope covered, so that no light at all is captured.


Combined with the useful resources mentioned below, the astrophotography tutorials found on this website can help you effectively photograph deep sky objects from your own backyard. The tutorials covering Milky Way photography and wide-angle shots are there for amateur astrophotographers who prefer to capture impressive landscape night photography scenes. In November , I published a new astrophotography image processing tutorial to my YouTube channel. This video walks you through the techniques I use in Photoshop when processing deep sky objects captured in my backyard. Polar alignment is crucial for a sharp image.
