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 the entire signal perceived in the field, it is possible to stack images without limits and field loss.

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 ...
Does Vespera Passengers feature a field derotator?
Like Vespera, Vespera Passengers does not incorporate a mechanical field derotator. The field of view will change as images are stacked. The absence of a field derotator will have only a limited effect (stars at the edge of the field) on photo ...
What is the field of view of Vespera Passengers?
The field is 2.4° x 1.8°. It's larger than Vespera & Stellina.
What is the field of Vespera?
The field is 1.6° x 0.9°. To give an idea, twice the moon enters entirely in the sensor's field of view.
Can we use any other manufacturer's filter on Vespera?
No it will not be possible to use existing filters, as Vespera will adapt its image processing and object suggestions, based on filters that will be used, by detecting the type of filter. Moreover, a full-aperture filter involves specific ...
