[Sticky] What is Drizzle and when can I benefit from it
- https://www.astropixelprocessor.com/community/tutorials-workflows/drizzle-for-mono-cameras/
- It's rarely mentioned in the astrophotography sphere on the internet fora but it's really important to realize. Drizzle is injecting Signal & Noise of 1 original pixel into several pixels in the target pixel grid for integration. This results in sharper integrations possibly, but also in more noise as a …

- Nov 4. Nov 4 Drizzle: A Game-Changer For Star Trackers Users. Andrea Minoia. Editing. For many of us astrophotographers on a budget and beginners, to buy a star tracker is the first step towards serious astrophotography. Star trackers are the perfect machines for portable and wide-field astrophotography, but you’ll soon want to do more than that.

- It expands the resolution of the image by taking 1 pixel and expanding it into 2×2 pixels (of course there is a lot of math involved to make this work well). If your image is under-sampled (when you zoom in on a star, is it blocky?), drizzle can help smooth things out. Drizzle increases resolution but it also increases noise.

- Drizzling is commonly used by amateur astrophotographers, particularly for processing large amounts of planetary image data (typically several thousand frames), drizzling in astrophotography applications can also be used to recover higher resolution stills from terrestrial video recordings. [1]

- To use drizzle to de-rotate your images, ensure that you have setup your camera, focused your telescope, and determined the length of your exposures as you normally would. Perform the following procedures: 1) Ensure that you have selected drizzle from the Image Process drop down list as seen on page 5.
Why and How to Dither Your Astro Images - Sky

- Drizzle is a technique that improves the resolution of undersampled images. It was originally developed for the Hubble Space Telescope, where the optics resolved more detail than the size of the CCD pixels on the WFPC2 camera would allow. Professional astronomers have a saying: “dither or die.”

- Drizzle will increase the size of the dataset by the nature of how it does its job slicing up and recombining the pixel fragments. For instance, an x2 drizzle from DSS results in an image four (4) times the size of the native.. x3 produces an image nine (9) times the size of …

- A question that frequently come up-one that I have asked many times. The only real way to answer it is to have drizzle and non drizzle versions of the same data side by side. To remove the effects that different processing can have on the image, processing has been removed from the equation. No p...
