What is the main advantage of the CPC Deluxe 925 HD's EdgeHD optics?
The primary advantage is a flatter, coma-free field of view. EdgeHD optics correct for optical aberrations that cause stars at the edge of the field in a standard Schmidt-Cassegrain to appear elongated or out of focus. This results in sharp, pinpoint stars across the entire 42mm image circle, which is critical for imaging with large-sensor cameras.
Can I do long-exposure astrophotography with the CPC Deluxe 925 HD?
The CPC Deluxe can track accurately for up to 30 seconds without a wedge. For longer exposures, add the HD Pro Wedge, which lets you polar align with All-Star Polar Alignment and use Permanently Programmable Periodic Error Correction.
Is the CPC Deluxe 925 HD portable enough for one person to set up?
The combined optical tube and mount assembly weighs 58 lbs (26.3 kg), and the separate tripod weighs 19 lbs (8.6 kg). The fork arms have rugged carrying handles.
What does the internal 16-channel GPS do for the CPC Deluxe 925 HD?
It supplies your latitude, longitude, date and time to the NexStar+ hand control, so you do not have to enter them before SkyAlign.
How does the Fastar compatibility on the CPC Deluxe 925 HD work?
The secondary mirror can be removed and replaced with a third-party lens assembly, sold separately, for ultra-fast f/2 imaging.
What is the purpose of the mirror clutches on the CPC Deluxe 925 HD?
The mirror clutches are designed to prevent "mirror flop" or image shift during long-exposure astrophotography. The focusing mechanism works by moving the primary mirror. Once you have achieved perfect focus, tightening the two clutch knobs locks the mirror in place, preventing it from moving or tilting as the telescope tracks across the sky, and loosen them before you refocus.
What kind of power supply do I need for the CPC Deluxe 925 HD?
The telescope requires a 12 VDC, 1.5A power source with a tip-positive connector. It runs from the supplied 12V car battery adapter or an optional power supply.
Can I control the CPC Deluxe 925 HD with my phone or computer?
Yes. You can control the telescope from a PC using the USB port on the NexStar+ hand control and the included Celestron Starry Night software. For wireless control from a smartphone or tablet, you can add the SkyQ Link 2 WiFi Module.
What is SkyAlign and how does it work?
SkyAlign is Celestron's easiest alignment method. After the internal GPS sets your time and location, the hand control prompts you to point the telescope at any three bright objects in the sky. After you center each one, the telescope is ready to locate and track objects.
