Hello,

I have the following subframes taken with a Nikon D5300 cooled and modded
-18 LIGHTs Halpha of 1600 ISO and 600  with FLATS , DARKS and FLATS
- 9 LIGHTs Halpha of 200 ISO and 600 seconds with FLATS , DARKS and No FLATS

How should I stack them?

Thank you

Hi @eldoctorbacterio

Thank you for your question and welcome to  the forum 😉

Best is to first calibrate the 2 sets separately and save them in 2) calibrate. Make sure calibration is working nicely and I suggest to make a Bad Pixel Map if you haven't done so already.

https://www.astropixelprocessor.com/community/tutorials-workflows/creating-a-bad-pixel-map/

Then if you have correctly calibrated both sets of frames, then simply load all of the the calibrated light frames and process starting from 3) Analyse Stars.

Let me know if this helps and if you have any other question.

Kind regards,

Mabula

Thank you very much Mabula!

Wellfinally I managed merge all my data from the two series, 200 ISO + 1600ISO.

I very happy with your software: the result is better than what I´ve  reached with Pixinsight.

And the best is that the simplicity: I just load directly ALL my LIGHTS, DARKS, FLATS and BIASS from the two series.

Maybe I should have listenning to your advice about the proper workflow, but anyway this is the result without any post-processing
