Celestron RASA 8" Telescope w/ Computerized CGX Mount Bundle

Theek hai, likhta hoon — 800 words, natural tone, no AI feel, both beginners and advanced ko cover karta hua.

If you are serious about deep-sky astrophotography, the Celestron RASA 8 is one of those telescopes that genuinely changes how you image the night sky. Paired with the CGEM-II computerized equatorial mount, this bundle gives you a complete, ready-to-image setup right out of the box.

Sky Deep is Pakistan's only authorized Celestron dealer, so what you get here is the real thing — with full warranty and local support behind it.

What Makes the Celestron RASA 8 Different?

Most telescopes for astrophotography sit somewhere between f/5 and f/10. The RASA 8 runs at f/2.0. That is an extremely fast focal ratio, and it makes a very real difference when you are imaging faint nebulae or galaxies.

At f/2.0, you collect light roughly 25 times faster than an f/10 system. What that means in practice is that exposures which would normally take 10 to 15 minutes can be done in under a minute. For Pakistani astrophotographers dealing with light pollution or short imaging windows, this is a serious advantage.

The optical design is a Rowe-Ackermann Schmidt Astrograph — a system built specifically for imaging, not visual use. It delivers sharp, flat stars across a 22mm corrected image circle, which covers most modern CMOS, CCD, and mirrorless camera sensors with no vignetting at the edges.

The CGEM-II Mount — Why It Matters

A great telescope on a weak mount produces blurry images. The CGEM-II is a proper German equatorial mount with a 40 lb payload capacity and low-cog DC servo motors that track the sky accurately and quietly.

It slews at 4 degrees per second and tracks at sidereal, solar, and lunar rates. The NexStar+ hand controller gives you a database of thousands of objects, and the mount is fully compatible with Celestron's CPWI software and StarSense technology for automated alignment and plate solving.

For beginners, this means the mount does the hard work of finding and tracking objects for you. For advanced imagers, the autoguide port, AUX ports, and USB 2.0 connectivity mean you can integrate it into a fully automated imaging rig without limitations.

Who Should Buy This Bundle?

If you are just getting into deep-sky imaging and want a setup that delivers real results without years of learning curve, the RASA 8 with CGEM-II is one of the best starting points at this level. The fast focal ratio means you will get usable images in your first session, not after months of frustration.

If you are already imaging and want to move up from a slower refractor or SCT, the jump to f/2.0 will immediately show in your data. Shorter sub-exposures, better signal in light-polluted skies, and a wider field of view all come together with this system.

The only thing to keep in mind is that the RASA 8 is a dedicated imaging astrograph. It does not use eyepieces for visual observing the way a traditional telescope does. It is built for cameras, and it excels at that job.

Common Questions

Q1: Is the Celestron RASA 8 good for beginners?

Yes, if you are specifically interested in astrophotography. The fast f/2.0 ratio means shorter exposures and easier results. It is not a visual telescope, so if you want to look through an eyepiece, this is not the right choice.

Q2: What camera works with the RASA 8?

 It works with most modern CMOS and CCD astronomy cameras, as well as mirrorless cameras using the included M42 and C-thread adapters. The 22mm corrected image circle covers APS-C sensors well.

Q3: Does the CGEM-II mount need a power source?

Yes. It runs on 12V at 3.2A. A portable power station or battery pack works well for field use. Sky Deep carries compatible power accessories in the mount accessories section.

Q4: What is the price of the Celestron RASA 8 bundle in Pakistan?

The current price at Sky Deep is Rs. 1,401,308 PKR. This includes the RASA 8 OTA, CGEM-II mount, tripod, counterweight, hand controller, and all adapters listed above.

Q5: Can I upgrade or expand this setup later?

 Yes. The CGEM-II mount supports autoguiding, CPWI software, and StarSense. You can add a guide scope, guide camera, electronic focuser, and narrowband filters over time without replacing the core setup.
