I am starting off in narrowband imaging and in Photoshop I can manually align Ha, Sii, O3 and have the freedom to blend each one although I am new to this. However manually aligning them is tricky. I know Registar can align all 3 into 1 aligned image (I have only just got the evaluation copy) but can it align all 3 so that when imported to Photoshop and merged they are already aligned? Or do put it another way how do folk use Registar to align narrowband images for onward processing in Photoshop? Some help would be really appreciated as I am a bit stuck. This is new to me.
