Depending on the field of view of your imaging rig, you might find yourself wanting to create mosaic images. Creating a mosaic is done early on in the normal image processing workflow (RGB, LRGB, LRGB+HA, Narrowband).
You can make your mosaic as large or small as necessary. The only major challenge is the amount of time required to capture enough light frames within each section of the mosaic to provide an adequate signal/noise ratio.
Once the images are captured, pre-processed, cropped and have had the background extracted, we can start merging the sections together.
