|Bubble Nebula||NGC 7510 - an open star cluster|
|Outer arm of Sharpless-157||Core of Sharpless-157|
- I used a more elaborate preprocessing in Pixinsight, using weights, drizzling (and ran into some issues that turned out to be a bug in the ImageIntegration script)
- merging the images to a mosaic (and an issue to align the individual frames)
- I needed to use both HRDMultiscaleTransform to get details in the brightest areas of the image, and also LocalHistogramTransformation to get details in the other parts of the nebulae
- and finally using LayerMasks in Photoshop to fix local issues of a process (instead of trying to create a specific mask in Pixinsight) - for which I had to figure out how to transfer images from Pixinsight to Photoshop and back
But it was worth the effort!
... and finally I had to figure out how to upload this large image to Blogger ...
