Frequently Asked Questions about the Vespera (II Pro) telescope

Automatic calibration can affect acquisition speed, as the telescope needs extra time to apply dark frames, bias frames, and flat frames. While this process improves image quality by reducing noise, it may slightly extend the total processing time. File size is generally not significantly affected, as calibration is applied before the final image is saved.

When automatic calibration is enabled, the telescope performs corrections like dark frame subtraction and flat frame adjustments, resulting in a cleaner image. When disabled, these corrections aren’t automatically applied, requiring manual post-processing to correct noise and sensor artifacts.

Yes, automatic calibration remains active when capturing mosaics and when planning observations through Plan my Night. This ensures that each capture within the mosaic undergoes the same image corrections, producing a uniform final result without visible transition lines between individual captures.

Yes, the Universal Master Dark can be used in software like DeepSkyStacker, PixInsight or AstroPixelProcessor. This calibration file helps remove sensor noise and improve image quality during manual stacking, which is particularly useful when you want to edit the raw 16-bit TIFF files without the telescope’s built-in automatic corrections.

Yes, when automatic calibration is enabled, the dark, bias, and flat corrections are already applied to the 16-bit TIF files. This means these files are already optimized for direct use, but it limits the ability to apply your own calibration files. If you want full control over image processing, it’s better to use the raw FITS files, where calibration can be performed manually.

Yes, automatic calibration is applied to the FITS files, meaning dark, bias, and flat corrections are automatically processed. This results in a cleaner image, but if you want full control over processing, you should save raw uncalibrated frames and calibrate manually in software like PixInsight or DeepSkyStacker.

With automatic calibration, the telescope uses pre-stored dark frames (Universal Master Dark) to correct noise and hot pixels without user intervention. In expert mode, you can capture your own dark frames under specific conditions, which can be useful when sensor environment varies significantly. Manual dark frames can be more accurate when captured at the same time and temperature as your exposures.

You can check this in the settings of the software you’re using with the Vespera Pro. When automatic calibration is enabled, corrections are applied in real-time. Sometimes the software may display a notification about calibration status, or you can check this by looking at the histograms or file metadata.

The Vespera’s built-in catalog contains thousands of deep-sky objects, including star clusters, nebulae, and galaxies. This includes objects from well-known catalogs such as Messier, NGC, and IC. The exact number may increase with software updates.

No, the Vespera is not designed to track fast-moving objects like satellites or the ISS. The telescope is optimized for deep-sky and planetary observations, which require long exposure times and stable tracking. Tracking satellites requires specialized mounts with fast motors.

No, currently the Vespera doesn’t support manual input of astronomical coordinates. The telescope works with a built-in database and automatic object recognition. This means you can select objects from the catalog, but cannot directly input coordinates to observe a specific area of the sky.

Currently, there is no official announcement of a Vespera model with a larger lens aperture. Vaonis, the manufacturer, is currently focused on compact and user-friendly smart telescopes like the Vespera II and Vespera Pro. If a model with a larger aperture is released in the future, it will likely be announced through official channels.

You can retrieve your photos through the Singularity app. Go to the gallery within the app and select the desired images to download to your smartphone or tablet. If you want to save them to a computer, you can connect the Vespera via Wi-Fi and transfer files manually. Some models also support storage via external USB drives.

The Vespera Pro comes with a mechanical lock to protect the lens and internal components. Make sure the lock is properly secured during transport to prevent damage. Consult the manual for specific instructions on unlocking and locking the telescope.

No, an internet connection is not required to use Vespera. The telescope works via a local Wi-Fi connection with your smartphone or tablet. An internet connection is only needed for software updates and downloading additional content.

Yes, the maximum apparent magnitude depends on exposure time and lighting conditions. Under ideal conditions, the Vespera can detect stars up to magnitude 12-14, but this can vary depending on light pollution and atmospheric transparency.

No, the Vespera does not have a built-in heating system to prevent condensation. In cold or humid conditions, you can use a separate dew shield or heating band to keep the lens free from condensation.

The Vespera’s Wi-Fi range is approximately 10-15 meters in open space. This can decrease with obstacles such as walls or other signal interference.

The Vespera is equipped with a built-in lithium-ion battery. This provides an average usage time of 4 to 8 hours, depending on ambient temperature and the use of Wi-Fi and other features. For longer observations, an external power bank can be connected via USB-C.

You can set your desired image formats through the Singularity app in the settings menu. Here you can choose to save your captures as JPEG, TIFF or FITS. FITS is particularly useful for astrophotography and post-processing, while JPEG and TIFF are suitable for quick and easy viewing.

To free up memory, you can delete old images and captures through the Singularity app. Go to the storage settings and delete unwanted files. You can also transfer your captures to a computer or external drive before deleting them.

Linux users can use the Vespera’s Wi-Fi connection to access stored images. Files can be transferred via a web interface or SCP/FTP client. FITS files can be opened in astrophotography software like Siril or GIMP.

Mac users can download files through the Singularity app and then transfer them via Airdrop, USB, or a cloud service. FITS files can be opened in PixInsight or AstroPixelProcessor.

Windows users can easily transfer files via Wi-Fi or by opening the Vespera’s storage folder in the Singularity app. The images can then be edited in software like DeepSkyStacker or Photoshop.

The Vespera is designed to operate at temperatures between -10°C and 40°C. At extremely low temperatures, the battery may discharge faster and condensation may occur. At high temperatures, it’s recommended to keep the telescope out of direct sunlight.

The Vespera and binoculars have different applications. Binoculars are ideal for direct observation, without power or technology. The Vespera offers digital astrophotography, longer exposure times, and automatic tracking. This makes it possible to capture deeper and more detailed images of deep-sky objects that remain invisible with binoculars.
