To test this new version of this software,SIRIL, which is really a precious help for short exposures imaging, I chose an old capture of M57 (SER-8b-500ms) that I made in 2016.
It has an option, among others, which is interesting, it's the Drizzle.
Quickly: the Drizzle is a function that allows you to recover information lost / hidden by sub sampling.
The Drizzle works well if there is:
-a number of high frames
And that's exactly the components of deep sky acquisition in fast mode!
We capture thousands of brutes, no autoguiding + a bit of wind + EP and we are under sampled (but not too much anyway).
Moreover, if we associate the deconvolution with the Drizzle we manage to highlight details on these small nebulae more easily than the deconvolution alone.
300mmF4 barlow 2x and asi224mc
frames:10000/15000, gain 500, expo:500ms
And a comparison with the big one in space to just see if my details are not artifacts...
