How does Mosaic mode work?
During a classic observation, the part of the sky visible in the image (the field) has a fixed size corresponding to the optics of the instrument.
On Stellina, the field is about 1.1° x 0.7
On Vespera, the field is about 1.6° x 0.9°
By making an observation in mosaic mode, you can enlarge this field to 4 times the area of the normal field.
