Description

MouseOver shows the reprocessing improvement

Notes 2023 : reprocessing of SHO and RGB images
- SHO : BlurX, NoiseX, StarX, HT, ColorSat, CurvesTransform
- RGB : SpecCC, HT, StarX, CS
Finally : Unscreen RGB_Stars with SHO

Notes 2020 :
This is our first light in ou new remote observatory in Spain (e-eye) that I share with my friend Fabian !!!!!!
We have not get our guiding camera working yet, so we limit exposures to 2 min UNGUIDED with our CEM120EC2 mount. The tracking with encoders was perfect, only limited by equipment flexure that could be seen on some 5 min test exposures.

I select this nebula because I found it so beautiful.

It was very easy to acquire the 24 h total exposure, as our system worked flawlessly all night.

Concerning the process (in PI) :
- dark and flat calibration, cosmetic correction, registration, integration and mure denoise of each channel.
- build SHO and RGB images
- delinearize with HT
- build star mask with starnet++
- add RGB color to SHO image stars under star mask
- color sat
- TGV denoise
- adjust L channel under star mask with Curve Transformation
