Learn how to take great astro photos using remote telescopes located around the world! ItРІР‚в„ўs fun, easy, and thereРІР‚в„ўs a whole community of astronomers just like you to interact with.Р”В¬heck out my FREE book for more details! You can download the book right away and start taking your own images like this. If not, continue to the next section and download and install the software. I assume that you have both DSS and GIMP installed. The steps to process the images are involved so you need to follow them carefully and this tutorial includes screenshots throughout to help clarify points. The link to download the files is in the sections that follow. This article includes sample FITS files of an observation of NGC 1514 for you to download so you can follow along. Final Edits РІР‚вЂњ this is where we use GIMP to perform the final changes to the image.Combination, Colorization, and Blending РІР‚вЂњ this is where we use GIMP to do the bulk of our editing and where we combine the masters into a final RGB image.DSS Stacking РІР‚вЂњ this is where we use DSS to stack individual FITS files to produce a master for each color.

Software acquisition and Installation РІР‚вЂњ if you donРІР‚в„ўt already have GIMP and DSS installed, this is where you do that.

As a result, this tutorial is split into four broad parts: This is a long tutorial so it helps to understand the overall process thatРІР‚в„ўs binding all of the steps together.Р”ВeepSkyStacker is very good at stacking images however anyР”Р„dvanced image processing needs to be done using something like GIMP or

This is the key benefit of stacking multiple exposures: you have a much better signal to noise ratio.

This image is a lot less noisy and thereРІР‚в„ўs much more detail in the nebula. I stacked these exposures using DSS and combined them into a single LRGB result image as shown: The image has some detail in it, however, it is very noisy. I took an observation of NGC 1514 made up of five observations of LRGB exposures, resulting in a total of 20 files (five each of L, R, G, and B exposures).Р”Р‡or the sake of comparison, I used FITS Liberator to combine one set of LRGB exposures into a final image (I followed the directions in РІР‚Сљ Using FITS Liberator To Create An RGB ImageРІР‚Сњ), and came up with the following: This is the recommended approach because it produces a better result than you can achieve using GIMP. Find the article here: Creating an LRGB Image Using DeepSkyStacker, JS9, and. I also wrote an updated article that uses DSS, JS9, and for a better result than you can achieve using DSS and GIMP. ThereРІР‚в„ўs a link in this article to another article that explains how to use. Like GIMP, is free to use and you donРІР‚в„ўt have to install anything on your system to use it. While GIMP is useful, a more modern approach is to use, a browser-based image editor thatРІР‚в„ўs very similar to Photoshop. Note the DeepSkyStacker is only available for Windows.

YouРІР‚в„ўll need to have both DSS and GIMP installed to follow the directions in this tutorial. This article covers using DSS to stack images and then produce a final RGB image using GIMP. Into a TIFF and manually align it, an automated process is faster and moreР”ВeepSkyStacker (DSS) is free software thatРІР‚в„ўs designed to make the process of combining (stacking) images easier, faster, and more accurate than doing it manually. While you could certainly convert each FITS file With multiple exposures, you end up with more than one FITSР”Р‡ile for each color filter. With longer exposure time on the target, you get a higher signal to noise ratio and better overall quality image. While this works well, real-world observations are usually made up of multiple exposures to get a longer total exposure time on a target. Using GIMP To Combine Three Mono Images Into One RGBР”Р„ number of my recent articles have covered creating RGB images using only a few FITS files, often one FITS file for each color filter.Update: If you are looking for information about combining three monochrome images into one using GIMP, visit this article:
