A little experiment to combine 10 X 10 minute Ha images as firstly a Luminance channel and secondly the same image debayered to colour as a colour overlay over the top of 5 X 10 minute RGB images captured with QHY8 OSC Cooled CCD.
Alignment proved to be the hardest task to overcome with very few bright stars in the Ha images. Alignment was completed manually using IP3 and the 3 images were combined in PS CS3.
I have included the Ha image but on close inspection I notice a little missalignment of the visible stars in this image. The single frames show no trailling at all.
I hope you like the image, not sure about it myself.
