Automatically Correcting Column Defects Using PixInsight
In a previous article, I showed you how to use PixInsight’s CosmeticCorrection process to remove column defects from an image. In that article, you had to determine the location and length of defects as...
Assembling a Mosaic Using PixInsight
A mosaic is a single large image made up of a number of smaller images. Astrophotographers use mosaics to create high-resolution images of regions that are larger than their telescope’s field of view. While...
Horsehead Nebula and Region
This is the Horsehead Nebula, or Barnard 33, and the surrounding region: The image is dominated by the glow of the star Alnitak, or Zeta Orions on the left side of the image, and...
Difference Between Dynamic and Automatic Background Extractor In PixInsight
PixInsight offers two powerful background modelization methods: AutomaticBackgroundExtractor (ABE) and DynamicBackgroundExctractor (DBE). Many people simply use ABE and are satisfied with the results, thinking that PixInsight chooses the optimal background for you, when in...
Processing a Slooh.com Image In PixInsight Revisited
Note: This article discusses manually processing a Slooh.com image using PixInsight. Refer to this article for a detailed workflow that takes advantage of scripts to simplify the workflow yet still take advantage of PixInsight’s...
Processing a Slooh.com Image Using PixInsight
Update: I have published a PixInsight workflow for processing Slooh.com images. The article discusses the workflow and has links to articles that discuss the details about each step. I recently took an image of...
Processing a Noisy Slooh.com Image Using PixInsight
I took an image of Hickson Comapct Group 68 a couple of years ago. I never processed it because it was based on a single mission using the Canary Two telescope, so the exposure...
Correcting Column Defects Using PixInsight
A common problem in astrophotography is column defects. A column defect occurs when a column of pixels is on even though that was not present in the actual image. Here’s a sample of NGC...
An Overview of PixInsight’s Screen Transfer Function (STF)
The Screen Transfer Function process in PixInsight stretches an image so you can see it on your screen. It’s also an important part of processing your images since it allows you to see your...
