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 ...
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 ...
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.
Is Stellina more powerful than Vespera?
Stellina has a larger aperture and focal length than Vespera. It integrates in addition to Vespera a light pollution filter, an anti-fog system, a field rotator, a USB port for raw file recovery, ... It also offers a better resolution. For people ...
How does Vespera handle setup/initialization?
Vespera is automatically set up / initialized in less than 5 minutes. First, Vespera retrieves the exact GPS position as well as the date and time of observation thanks to the user's smartphone/tablet. Then, Vespera will scan the sky. If the sky is ...
