Celestron EdgeHD vs XLT 

Are you a new astronomer who now into a planetary imaging, or you just want to upgrade or add your scope collection? Many options to start your experiences, but now we will review a telescope from Celestron which famous worldwide for its Schmidt-Cassegrain telescopes that allows you do both planetary visual and imaging. Coming from the same brand, Celestron EdgeHD vs XLT (telescope) are Celestron’s Revolutionary Schmidt-Cassegrain design. Before we jump to Celestron EdgeHD vs XLT (telescope) comparison, let’s take a closer look of celestron edge hd vs xlt (telescope) so you will understand more and help you choose based on your personal need.

Celestron EdgeHD

The Schmidt-Cassegrain telescope (SCT) design is popular among amateur astronomers. It offers long focal length and large aperture but still manageable and affordable. The new optical system of Celestron is EdgeHD, the evolution of classic Schmidt-Cassegrain. It can be used in visual and for planetary and lunar photography. Because of its feature, the Celestron EdgeHD named as versatile telescope.

This revolutionary of Celestron aplanatic EdgeHD optical system virtually eliminates spherical aberrations such as field curvature and off-axis star coma at up to 20mm off-axis and the diameter of the coma-free is 40mm. They increased refraction or reflection of the light rays when they strike near mirror’s edge. This produced a great flat-field images three times flatter than a standard Schmidt-Cassegrain.

The Celestron EdgeHD are capable with wide-field viewing in modern wide-angle eyepiece designs and produce sharp-edge images with DSLR cameras and large-sensor CCD cameras. The high quality of the optical combined with large flat field also large apparent field produce stars will be point across the whole field. The lower obstruction produces higher contrast which is a great offer from the unit. This makes the Celetron EdgeHD telescopes represent a significant improvement from classic SCT design.
The high quality of the optics combined with high focal length and lower obstruction makes the Celestron EdgeHD is excellent for lunar planetary and photography with DSLR camera. The Celestron EdgeHD also excellent for deep-sky long exposure imaging astrophotography. The secondary mirror of this unit is supported with corrector plate that protect internal optical elements also prevents from diffraction spikes.

Celestron XLT

The Celestron XLT is one of the Schmidt-Cassegrain telescope (SCT) design. The engineers of Celestron developed XLT, the high-quality optical coatings to increase transmission in telescope which is be one of the most important factors of Schmidt-Cassegrain telescope, making for an incredible value. The XLT optical coatings prevent lost light reflection and absorption and gathered more amount of light to reach the CCD sensor and enhance views for visual observes when do astronomical imaging.

There are three major components of Celestron XLT design. The unique multi-layers mirror coating made from precise layers quartz, titanium dioxide, and silicon dioxide make the reflectivity is flat across the spectrum and optimizing both imaging and visual observing. The multi-layer anti-reflective coating made from a rare element that give a wider band pass than other competing coatings. The last components used high-transmission water white glass for corrector lens that give improvement in image brightness. The water white glass transmits 3.5% better transmission than soda lime glass coating and the Celestron XLT give 8% improvement of transmission for its water white glass.

The Celestron XLT is like other SCT telescope that has many advantages of compactness and light weight also the handle is convenience and the corrector cover rotate doesn’t easily to fall. However, some users said that the primary mirror is moving when you observing at high power or planetary imaging caused mirror flop that can ruined long exposures.

Celestron Edge Hd vs XLT 

After a closer look of Celestron EdgeHDvs XLT (telescope), let’s jump to Celestron EdgeHD vs XLT (telescope) comparison. So you will find a brief different of both units and decide which one is best for your need. Read also: Celestron Edge HD 8 vs 9.25.

The Optic

Both Celestron EdgeHD vs XLT (telescope) absolutely has different optical design that Celestron offers. The EdgeHD optic lens is coma free and the second lens inside the baffle tube produces a flatter field image than standard STC design. The closer place of primary and secondary mirror allow larger illuminated field of view. Meanwhile the Celestron XLT its optical coating system allow to minimize reflections and better transmission that optimizing imaging and visual observing.

Locking System

The Celestron EdgeHD has primary mirror lock while the Celestron XLT does not have. This lock system keeps the primary mirror not moving and give you convenience for observing.

Ease Use

Both of Celestron EdgeHD vs XLT (telescope) are ease to use and have the light weight. The good portability of both telescope for amateurs.

Usage

The Celestron EdgeHD vs XLT (telescope) are both great for planetary or lunar visual and imaging. However, some users reviews that the XLT is not good enough for long exposure, its better to use for short field like for moon, lunar, and planets, it result is superb. The Celestron EdgeHD is perfectly work for high planetary imaging and long exposure astrophography. However, because the EdgeHD is mainly for imaging, the EdgeHD wins with its high-quality image. But if you only need for visual, better to use the XLT.

The Price

The Celestron EdgeHD vs XLT (telescope) have a significant different price as it has different feature too. According from internet price in AmazonThe Celestron EdgeHD is around $1,339.00 – $5,999,00 for its optical tube. Meanwhile the price of the Celestron XLT optical tube is around $478.49.

Conclusion

The Celestron EdgeHD vs XLT (telescope) are worth to buy. Now it depend on your budget and need because it has huge different amount of price. If you into astrophography, it is better to purchase the Celestron EdgeHD because it could produce high quality image and good for long exposure. Meanwhile if you only need to do planetray visual, you can choose the Celestron XLT instead of the EdgeHD one. Both could produce super visual observing and can do astrophography, but the Celestron EdgeHD wins this case. The Celestron EdgeHD vs XLT (telescope) are also easy to use for beginner or amateur astronomer.
