2. Caratteristiche principali

The Askar 80PHQ Telescope boasts several advanced features for superior performance:

• Progettazione ottica: 3+1 quadruplet lens structure with two ED glass elements for effective chromatic aberration reduction and enhanced clarity.
• Integrated Lens Combination: A unique optical system where all lenses work together, ensuring better vignette control and superior image quality without needing external correctors.
• Rapporto focale: f/7.5, providing a balanced focal length for various astronomical observations and imaging.
• No Back Focus Calculation: Simplifies setup as there's no need to calculate back focus distance within connection limits.
• Flatfield Optical Design: Eliminates the need for an additional 1x flattener, streamlining the imaging process.
• Finitura premium: Ivory and pimply coating on the main tube for improved grip and aesthetic appeal.

3. Componenti finitiview

Familiarize yourself with the main components of your Askar 80PHQ Telescope:

• Gruppo tubo ottico: The main body housing the lenses.
• Focheggiatore: Mechanism for adjusting focus, typically with fine and coarse adjustments.
• Tube Rings: Securely hold the optical tube to the mounting plate.
• Piastra a coda di rondine: Attaches the telescope to a mount.
• Maniglia: For easy carrying and mounting.
• Scudo antirugiada: Extends from the front of the telescope to prevent dew formation on the objective lens and block stray light.

4. Installazione e assemblaggio

Follow these steps to assemble your Askar 80PHQ Telescope:

1. Disimballaggio: Rimuovere con cautela tutti i componenti dall'imballaggio. Verificare che non siano danneggiati.
2. Montaggio del telescopio:
   • Attach the dovetail plate to your astronomical mount. Ensure it is securely fastened.
   • Place the optical tube, secured by its tube rings, onto the dovetail plate. Tighten the clamps on the tube rings to hold the telescope firmly.

3. Accessori di fissaggio:
   • Eyepieces (for visual observation): Insert your desired eyepiece into the focuser. Secure it with the thumbscrew.
   • Camera (for astrophotography): Connect your camera to the focuser using appropriate adapters. The 80PHQ's design simplifies this by not requiring complex back focus calculations.
   • cercatore: Attach the finderscope to its designated bracket on the telescope tube.

4. Dew Shield Extension: Extend the dew shield fully before observation or imaging to protect the objective lens.

5. Utilizzo del telescopio

5.1. Visual Observation

1. Mirando: Use the finderscope to locate your desired celestial object. Center the object in the finderscope's crosshairs.
2. Messa a fuoco: Look through the eyepiece and slowly adjust the focuser knobs until the image is sharp and clear. Start with coarse adjustment, then fine-tune.
3. Selezione dell'oculare: Experiment with different eyepieces to achieve varying magnifications. Lower magnification eyepieces (longer focal length) provide a wider field of view, while higher magnification eyepieces (shorter focal length) offer more detail.

5.2. Astrophotography

The Askar 80PHQ is optimized for astrophotography due to its flatfield optical design and integrated lens system.

1. Connessione telecamera: Ensure your camera is securely attached to the focuser using the appropriate adapters.
2. Allineamento polare: For long-exposure astrophotography, accurate polar alignment of your equatorial mount is crucial. Refer to your mount's manual for detailed instructions.
3. Focusing for Imaging: Achieve precise focus using a Bahtinov mask or software-assisted focusing tools. The focuser's fine adjustment allows for critical focus.
4. Guida: For exposures longer than a few seconds, an autoguider system is recommended to compensate for tracking errors and ensure sharp stars.
5. Image Acquisition: Use your camera's software or dedicated astrophotography software to control exposures, ISO, and other settings.

Nota importante: The Askar 80PHQ's integrated lens combination means you do not need to add an external 1x flattener, simplifying your imaging train and setup.

6. Manutenzione e cura

• Pulizia delle lenti: Only clean the objective lens when absolutely necessary. Use a soft brush to remove dust, then a specialized optical cleaning solution and microfiber cloth. Avoid touching the lens surface with bare hands.
• Pulizia dei tubi: Wipe the telescope tube with a soft, damp stoffa. Evitare detergenti abrasivi.
• Magazzinaggio: Store the telescope in a dry, dust-free environment, preferably in its original case or a padded bag. Ensure the dew shield is retracted and lens caps are on.
• Acclimatazione alla temperatura: Allow the telescope to acclimate to the ambient outdoor temperature for at least 30-60 minutes before use to minimize thermal currents within the tube.
