New PixInsight Tutorial for Sharpening Fine Details


Recommended Posts

Read here: http://lightvortexastronomy.blogspot.com/2015/08/tutorial-pixinsight-sharpening-fine.html

This tutorial covers the process of sharpening fine details in one's images, be they monochrome or colour. The tutorial covers the in-depth use of MultiscaleLinearTransform and Deconvolution with DynamicPSF, both on linear and non-linear images. ATrousWaveletTransform is normally used but as it is being phased out to obsolete by PixInsight developers, MultiscaleLinearTransform replaces it completely.

[uPDATE]: This tutorial is now back online after a corrective update. Deconvolution with DynamicPSF is now described strictly with linear images (as it should be). The order of presentation of Deconvolution and MultiscaleLinearTransform has been reversed to nail in the idea that both can be used - Deconvolution while the image is linear and MultiscaleLinearTransform later, ideally when the image is non-linear. Also made some edits to the text to ensure correctness and fluidity.

I bought PixInsight some time ago but really need some of my own images to work on. Hopefully after the next Star Camp I'll be able to do that. The tutorials are a great help in understanding how and why.

Thanks for the new ones.

Thank you, I'm glad they're helpful. I was thinking of uploading some of my old data of various objects and filters to a public area like Dropbox or Google Drive for readers to be able to download something to experiment on. I will sort it out this weekend if I can and announce it through my blog and Facebook page.

Thanks, that's a great idea.

Hi Derek,

It is done: http://lightvortexastronomy.blogspot.com/p/sample-image-data.html

This is a link to the new Sample Image Data page that contains a number of very different deep space objects, with broadband and narrowband data available (monochrome and colour). Have a read through the page if you're interested.
