Title: Batch Preprocessing without DARK and BIAS
Post by: TechnoPhil on 2015 November 15 05:32:30

Hello there,
I need help in order to understand how process a session.

Some month ago I took 40 frames of M101 but I didn't take any DARK and BIAS calibration frames.

If I start the script BatchPreprocessing inside PixInsight 1.8 an error occur. Please see the attached files.
I also tried the Image Integration script but the final image is in B&W and also not calibrated.

I other words, how can I process images without DARK and BIAS calibration frames?

Thank you for your help & regards.
Filippo

I can't try it right now, but I'm guessing you need to un-tick the "Optimize Dark Frames" option. Also you don't mention Flats, but I'm pretty sure you can't use flat's without calibrating.

In order to integrate manually you first need to debayer and then register before you integrate.

I discovered that I can use the StarAlignment Process, but the final image is in B&W.

Any other suggestions?

What is your camera? If it's DSLR or OSC then you must debayer.

Canon EOS 1200D (no mod.)
How can I do the debayer process without using the BatchPreprocessing script?

there's a BatchDebayer script you can use to debayer your raw files.

then StarAlignment on the debayered files, then ImageIntegration.
