[Vespera range] Does Vespera feature a field derotator?

No, our Vespera range does not include a mechanical field derotator. As images are stacked, the field of view will gradually rotate.

This absence has a minimal impact on photo quality, primarily affecting stars at the edges of the frame. Image stacking compensates for this effect, and the Mosaic function can be used to correct the field or achieve the desired framing.
