Description

I decided to allocate one hour to capture my own SN in NGC3254.

For some reason SGP failed to capture the blue channel.

So I made a synthetic color image using : R->R, R+G->G & G->B.

The processing was done in PI as follow (version original):

For each R ,G ,V, Ha, OIII & SII channels :

- Flat Field Dark Substraction

- Flat Field Integration

- Images Calibration (Dark Substraction and FF correction)

- Cosmetic Correction

- Image Registration

- Image Integration

- DBE or ABE

- Noise Reduction (Demure) with recommended variance

- Nonlinear Image Creation

Using each integrated channel :

- Created LRGB color image

- Color balance on stars

- Color saturation mask to protect dark area.

Final image adjustments performed in Iphoto on Imac (levels adjustments, +10% color sat, and deflip)
