M 45 my first attempt with Pixinsight
« on: 2015 December 10 14:42:25 »
Good evening.

This is my first processed Pixinsight.

I have serious problems to eliminate background noise.

Processing steps:
1-Dynamic Background extraction.
2-Background calibration.
3-Color calibration.
4-Multiscale four-Noise Reduction (ATW).
5-Masked stretch.
6-Morphological transformation (star size reduction).
7-Exponential transformation (with ATWT and PixelMath)
8-ACDNR.
9-SCNR.
10-Curves transformation.

Hi Stargate, excellent first result with PixInsight.

Only a recommendation about the stars cores. When you use Masked Stretch process it is possible that some saturated stars look pink in the center. Here you can see how to repair them before Masked Stretch.
Any way for your present image already processed, you can repair those stars at the end using a mask and the attached processes.
Saludos, Alejandro.

OK. Thank you.

I just process the image from the start preserving the complete full frame image sensor ( Canon 6D ) . I think improves slightly.
