After hours and hours of imaging work done on the Veil Nebula over the past month or so, the image is now complete! This image comprises a total of 90 hours of exposure time, in a nine-panel mosaic with 180 exposures, each 30 minutes long. 

My PixInsight tutorial update continues including features introduced in version 1.8.5. This time, I have updated my tutorial on colour-calibrating images to include the new process PhotometricColorCalibration, which works by plate solving your image and determining a true​ white reference for it. 

Following PixInsight version 1.8.5's release, I am proceeding to update some tutorials. The first update has gone to my lengthy tutorial on pre-processing images in PixInsight. The update has added the new LocalNormalization process and feature into the pre-processing of images. 

PixInsight 1.8.5 was released today, bringing with it a number of good updates to the platform. Everyone who owns a commercial licence for it will have received an e-mail notifying of the release. As always, you will have to uninstall your current version, download the new version from the website and install it separately (you cannot update to version 1.8.5 via the auto-update system).
