====== Before 'n After ======

{{ :image-1.jpg.jpeg?nolink&200|}}The Seestar is an amazingly capable instrument that can produce in seconds images of deep sky objects (aka DSOs).

However, the nature of almost invisible celestial objects, and thanks to sensitive modern CMOS digital cameras such as the Sony IMX462MC in the Seestar, means that the data we collect is mostly dark signals. Indeed, an unprocessed image can look almost completely black.

Happily, the Seestar can dig the details out of the dark end of the histogram and do the work to present us with surprisingly good images right out of the camera (images on the left). But with [[:post-processing|post-processing]] software and [[https://youtu.be/lMoSAHOgbD4?feature=shared|clever techniques]] we can transform that image into something spectacular (images on the right) that you can have professionally printed and hang on the wall ((COSTCO has a deal with Shutterfly that gives you 51% off listed prices and free shipping)).

Here is a collection of before and after images that demonstrate how surprisingly good images right out of the Seestar are, and how, with knowledge, effort, and talent they can be turned into treasures.
