Celestron EdgeHD 8" with Vixen bar and ESATTO 2" LPCelestron
Celestron EdgeHD 8" telescope with Vixen bar is a compact aplanatic Schmidt-Cassegrain telescope 203mm f/10 that, thanks to the ESATTO 2" LP low profile robotic focuser, becomes excellent for any application! It's perfect also for remote control since the ESATTO allows you to focus even with the primary mirror locked to eliminate image shift.
Celestron EdgeHD 8" with Vixen bar and ESATTO 2" LP: main features
Celestron EdgeHD 8" is an aplanatic astrograph telescope very light and compact. The high optical quality and very competitive price make it the ideal instrument for deep-sky and planetary visual use, and it's excellent in astrophotography. If you are looking for a versatile and easy to transport telescope, the EdgeHD is the right instrument for you. EdgeHD 8" is the more compact and affordable aplanatic Schmidt-Cassegrain telescope by Celestron, it's really portable.
- Celestron EdgeHD 8" with Vixen bar is a D:203mm F:2030mm f/10 aplanatic Schmidt-Cassegrain telescope
- ESATTO is the most advanced and affordable robotic focuser
ESATTO: the most advanced and affordable robotic microfocuser!
ESATTO 2” LP is the most compact low profile robotic focuser specially designed for telescopes with low backfocus and it can fit also the Celestron EdgeHD 8"! At just 32mm of thickness, ESATTO 2” LP provides a large 50.9mm free aperture with 10mm of travel, 5 kg of payload capacity and an incredible resolution of 0.03 microns per step! And like all the other ESATTO focusers, it comes with a USB-C port to let control it from your EAGLE or any Windows computer, ARCO port to let you connect to ARCO rotator, temperature probe port, WiFi connection to let you wirelessly control with a smartphone or tablet and dimmable LED lights!
The quality of EdgeHD aplanatic optics:
The Celestron challenge was to further improve their famous Schmidt-Cassegrain telescopes and the intention of creating a instrument without compromise, it brought the realization of these aplanatic optics, that return a stellar image comparable only to the famous RC or the CDK. The EdgeHD optics in fact guarantee perfect images, both in color level and in big 42mm circle field correction. Maintaining the same high quality standards, Celestron has succeeded in creating a new generation telescopes at a very affordable price. The construction of these optics is done by the combination of the best features of CDK and SCT. EdgeHD in fact are made with primary and secondary spherical mirrors. But, unlike the Schmidt-Cassegrain telescopes, in the optical path two lenses that correct aberrations are installed, in addition the stars appear perfectly point, without coma or field curvature.
The EdgeHD for visual and astrophotography
The high performance of this instrument can be noticed immediately during an observation, thanks not only to the optical design, but also to the great optical correction that offer results hat only few instruments can provide. Even with wide-field eyepieces, stars appear perfectly pinpoint from the center to the edges of the field of view. The resolution capabilities of this instrument is amazing, you can perform very high quality observations or imaging of double stars or planets. More, thanks to the large diameter, you can observe and take picture of many deep-sky objects, like galaxies, nebulae or star clusters. Thanks to a big 42mm diameter flat field, this telescope is ideal in astrophotography even with large sensor camera. Celestron also created dedicated accessories in order to be able to use this instrument with the maximum performances, such as the focal reducers and photographic adapters made specifically for the EdgeHD. In addition, these optics are compatible with the Hyperstar system, which leads the focal instrument from f/10 to f/2, much brighter and greatly reducing the exposure times. Photographically they are comparable only to high-level instruments with much higher costs.
