Celestron AVX 8 "Edge HD Telescope

The AVX8 "mount is an evolution of the Schmidt-Cassegrain EDGE HD. Specially designed to achieve optimum performance in astrophotography. It allows you to take photos in long exposures (f / 10 and f / 7) and with the FASTAR system you can take ultra-fast photos af / 2. It allows taking photographs crossing the meridian without having to reverse the position of the axis of ascension, so that you can take photos without interruption in the best area of the night sky.

The improved motor and the larger tripod mounting base improve the stability of the set, when working with a heavy system.

9.25 "(235mm) Schmidt-Cassegrain Edge HD optical tube with fully flat optical system. We have an aplanatic telescope free of field curvature aberrations and as. It will allow you to see detailed stellar images across the field without any traces or shapes of "donut".

Characteristics:

• Schmidt-Cassegrain EDGE HD 8 ”(203mm) af / 10 with STARBRIGHT XLT light transmission enhancement optical treatment.
• EDGE HD optical system perfectly corrects for field curvature and comma to deliver a truly flat field.
• Integrated vents with 60 micron hole size mesh filters to aid tube thermalization and remove hot air behind the primary mirror.
• FASTAR compliant, the tube comes with a secondary mirror that can be removed to attach a HYPERSTAR and take f / 2 photography.
• 9x50 optical finder to locate alignment stars.
• Gears with integer ratios and the programmable function of Permanent Correction of Periodic Error allow to eliminate the systematic errors present in the crowns and bisenphin.
• Self-guiding port for long exposure photography
• New motors that offer improved tracking and provide more power to manage overweight resulting from a poor balance of the frame.
• Updated industrial design to offer greater stiffness, less flex and improved aesthetics.
• The new design allows viewing or astrophotography beyond the meridian without interference from the motor housing housings.
• Improved latitude range. It can be used between 7 and 77 degrees latitude.
• Enhanced electronics with increased memory capacity for future content expansions.
• NexStar + control knob with multi-language programming (Spanish, English, French, Italian and German)
