Read this over carefully and you will know exactly what is being processed. Bold emphasis is mine. Several fields of the moon were imaged with each device [1]. Each field was imaged 9 times in succession [2].
The 9 images for each field were processed to create a median image [3]. The fields were then stitched together to create the lightly processed images [4] shown above.

[2] For each detailed portion of the moon, 9 correctly exposed images were captured.
[3] For each detailed portion of the moon, the 9 images were used to remove noise using a "median filter" noise reduction technique. Note that noise is NOT an artifact of lens quality. It is introduced by the camera sensor. https://en.wikipedia.org/wiki/Median_filter
[4] The images are then stitched together to create a minimally processed photo. 
NexOptic's terminology to describe the photo on the left is "lightly processed". This is exactly what they meant by "lightly processed".
IMHO. GLTA.
