[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.

How Vespera compensate for the lack of field derotator?
Vespera realizes unitary exposures of 10s. This is enough so that the field rotation is not visible on the raw images. Thus, the field rotation is compensated when stacking the images. Thanks to our image processing algorithms that take into account ...
Is the field derotator integrated?
Essential for the proper operation of the instrument, the field derotator is integrated and controlled by the onboard computer. Depending on the target star, the rotator adapts its rotation speed. This also changes the sensor field to achieve perfect ...
