CGX Equatorial 800 Edge HD

You have been doing astronomy for a while now. You want more. You want sharper images, flatter fields, and a mount that actually keeps up with your ambitions. The CGX Equatorial 800 Edge HD is exactly what serious astronomers in Pakistan have been waiting for.

This is not a starter telescope. This is a high-performance 8-inch Schmidt-Cassegrain with Edge HD optics. It sits on Celestron's powerful CGX computerized equatorial mount. Together, they give you a system built for both serious visual observing and deep sky astrophotography.

If you are ready to level up, the CGX Equatorial 800 Edge HD is the telescope for you.

What Is the Edge HD Optical System?

This is the most important thing to understand about this telescope. Standard Schmidt-Cassegrain telescopes have a curved focal plane. That means stars at the edges of your image look like little streaks instead of points. For visual observing, this is acceptable. For astrophotography, it is a problem.

Edge HD optics solve this completely. The CGX Equatorial 800 Edge HD uses a special aplanatic corrector built right into the optical system. It flattens the focal plane across your entire field of view. Every star — from the center to the very edge — looks like a sharp point of light.

The result is stunning astrophotos with no distortion. No external flattener needed. No extra accessories required. The correction is built in.

Complete Specifications

Here are the full specs of the CGX Equatorial 800 Edge HD:

Optical Design: Schmidt-Cassegrain (Edge HD Aplanatic) Aperture: 203mm (8 inches) Focal Length: 2032mm Focal Ratio: f/10 Eyepiece Included: 1.25-inch 40mm Plössl Finderscope: 9x50 straight-through finderscope Diagonal: 1.25-inch mirror diagonal Mount Type: CGX Computerized German Equatorial Mount (GoTo) Payload Capacity: 22.7 kg Coatings: StarBright XLT multi-layer coatings Drive: Dual servo motors with encoder feedback Connectivity: Wi-Fi, USB, hand controller port Database: 40,000+ objects via NexStar+ hand controller Software: Celestron's free planetarium app included

The 203mm aperture is a big deal. It collects nearly 2.5 times more light than a 130mm telescope. You see galaxies, nebulae, and clusters with real detail and depth.

The CGX Mount — Built for Astrophotography

The optical tube is only half the story. The mount is just as important. The CGX equatorial mount is Celestron's workhorse for serious imagers.

It uses a German equatorial design. That means it tracks the rotation of the Earth with precision. Objects stay centered in your frame for as long as you need. You can take long exposure images without field rotation blurring your photo.

The CGX carries up to 22.7 kg of payload. You can load it with the 800 Edge HD tube, a camera, a guide scope, and accessories — and it handles it all without strain. The dual servo motors with encoder feedback ensure smooth, accurate tracking all night long.

You can control the CGX Equatorial 800 Edge HD with the included NexStar+ hand controller. Or connect it via Wi-Fi to your laptop or phone. Celestron's SkyPortal app turns your tablet into a full planetarium and mount controller. You choose your target, tap the screen, and the mount slews there automatically.

StarBright XLT Coatings — Maximum Light, Every Time

Not all telescope coatings are the same. Cheap coatings reflect light and waste it. StarBright XLT coatings work differently. They maximize the amount of light that passes through each optical surface and reaches your eye or camera sensor.

The CGX Equatorial 800 Edge HD uses StarBright XLT on every optical surface. The result is brighter images, better contrast, and more detail — especially on faint deep sky objects like galaxies and nebulae.

This coating also improves planetary views. Jupiter's cloud bands look crisper. Saturn's Cassini Division looks sharper. The Moon shows incredible crater detail.

What Can You Image and Observe?

The CGX Equatorial 800 Edge HD handles everything. Let's break it down.

For planets, the 2032mm focal length gives you high magnification views. Saturn's rings are spectacular. You can see color bands on Jupiter and track its Great Red Spot. Mars shows polar caps and surface detail during opposition.

For deep sky observing, the 8-inch aperture pulls in faint light from billions of miles away. You can see the structure inside the Orion Nebula. The Andromeda Galaxy shows spiral arm hints. Globular clusters resolve into thousands of individual stars.

For astrophotography, the Edge HD flat field means pinpoint stars across your full camera sensor. Pair it with a ZWO cooled camera from our cameras collection for spectacular deep sky images. Add a narrowband filter from our filters collection to cut through Pakistan's city light pollution.

What Comes in the Box?

The CGX Equatorial 800 Edge HD comes fully equipped and ready to use:

The 8-inch Edge HD optical tube is included. The CGX equatorial mount and tripod come assembled and ready. The 9x50 finderscope helps you locate targets quickly. The 40mm Plössl eyepiece gives you wide, comfortable views right away. The 1.25-inch mirror diagonal makes viewing more comfortable at all angles. The NexStar+ hand controller gives you access to over 40,000 objects.

You take it out of the box, polar align the mount, and you are imaging that same night.

Why Buy From Sky Deep?

Sky Deep is Pakistan's only authorized Celestron dealer. That warranty matters when you invest over Rs. 12 lakh in a telescope system. Buying from an unauthorized seller means no genuine warranty, no after-sales support, and risk of getting a grey-market product.

We stock the full range of Celestron telescopes in Pakistan. If you want to compare similar advanced options, explore our Schmidt-Cassegrain telescopes collection or our full advanced level telescopes range.

Frequently Asked Questions

1. Is the CGX Equatorial 800 Edge HD suitable for astrophotography in Pakistan?

Yes, it is one of the best choices for deep sky astrophotography available in Pakistan. The Edge HD flat field optics produce pinpoint stars across your entire camera sensor. The CGX equatorial mount tracks accurately for long exposure imaging. Pair it with a cooled CMOS camera and narrowband filters for excellent results even from light-polluted cities like Lahore or Karachi.

2. What is the difference between Edge HD and standard SCT optics?

A standard Schmidt-Cassegrain telescope has a curved focal plane. Stars at the image edge appear stretched or elongated. The Edge HD design adds a built-in aplanatic corrector that flattens the focal plane completely. Every star across the full field is sharp and round. This makes the CGX Equatorial 800 Edge HD far better for astrophotography than a standard SCT.

3. Can the CGX mount handle additional accessories like a guide scope and camera?

Yes, easily. The CGX mount has a 22.7 kg payload capacity. You can mount the 800 Edge HD tube, a dedicated astrophotography camera, a guide scope, a guide camera, and still have room to spare. The mount is designed for exactly this kind of loaded, serious imaging setup.

4. Does the CGX Equatorial 800 Edge HD work with astronomy software on a laptop?

Yes. The CGX mount connects via USB and also supports Wi-Fi. You can control it with Celestron's free SkyPortal app on your phone or tablet. It also works with popular third-party astronomy software like Cartes du Ciel, Stellarium, and Sequence Generator Pro. This makes it very flexible for both visual and imaging sessions.

5. Where can I get support and training for this telescope in Pakistan?

Sky Deep is your complete support partner. We are the only authorized Celestron dealer in Pakistan. You can contact us for after-sales support at any time.
