Good morning. Can someone advise me on how I do the following process please.
I’m using a DSLR and have taken my lights, darks, flats and bias frames of the American Nebula and have them on my desktop. If I run APP I get a great image of the American Nebula showing it in the H-Alpha red colour. Whilst that looks great I’ve seen the same composition which was processed combining just the RGB & HOO channels and would love to know how I do this in APP?? Currently using the L-Enhance filter but have a Quadband on its way. If you can point me to any videos or give me a idiots guide that would be great.
You can have a look at this workflow: https://www.astropixelprocessor.com/community/tutorials-workflows/combining-r-g-b-with-ha-oiii-data-using-an-optolong-l-enhance-filter/
This is for such a filter, or at least you can adapt the workflow to work for such a filter as well. Be aware that color calibration with RGB and narrowband data is quite tricky. For the best workflow you can look at this workflow: https://www.astropixelprocessor.com/community/tutorials-workflows/hargb-and-lhargb-workflow-and-star-color-calibration/#post-10863
