We are very proud to introduce to you the RVO Horizon® 72ED. A small, lightweight 72mm ED refractor capable of both visual and imaging. This exciting new refractor incorporates the RVO colours in a beautiful glossy finish complimenting the contemporary matt white finish of the OTA itself. We have developed and manufactured this scope to meet all the needs of the modern day imager. The scope itself has high quality FPL-53 ED glass complete with matching zygo report so you can see for yourself, the quality of the lens you are purchasing. Not only that, we guarantee that all of our telescopes have a minimum 0.95 Strehl ratio for the highest quality images every time. In addition to this, we optically test each and every telescope that we sell to ensure you receive a perfect telescope each and every time. The scope is complimented with an aluminium lockable hard case for transport and storage. All featuring the brand new RVO Horizon® logo.

This telescope features a high quality 2" dual speed rack and pinion focuser. All CNC machined for a superb build quality and ultimate hold when accessories such as flatteners and CMOS/SLR cameras are attached. The 10:1 microfocuser ensures you can achieve the perfect focus every time. The focuser also features an indexed drawtube for precise and fast repositioning of targets. It also includes a focus lock so you can't accidentally alter focus when imaging.

Unlike most imaging refractors, this telescope has been designed to overcome all the issues with other telescopes. The main issue is balancing when you start to add heavy accessories and cameras. The Horizon® 72 ED comes as standard with a 30cm slotted vixen style dovetail bar, plus riser blocks fitted to the rings to ensure it misses the focus lock knob. Simply add your accessories, then slide your Horizon® OTA higher up the dovetail saddle and you are balanced. No additional accessories are required. The OTA kit also comes with a short vixen style bar to sit on top of the tube rings for adding our superb Horizon® Guide guidescope or other accessories with a vixen style clamp.

The Horizon® 72ED comes as standard with a 2" visual back, plus 2" - 1.25" adaptor. All connections feature non-marring compression rings for security and ease of use. Both 2" and 1.25" diagonals are fully compatible with the Horizon® 72. The long drawtube ensures achievable focus when using a wide range of diagonals and eyepieces. The OTA is also fitted with a universal synta style base for attaching a wide range of finderscopes and guidescopes. If you are looking for a lightweight alternative to the Horizon® Guide, then look at our 32mm mini Horizon guide scope, which is fully compatible. This will keep the weight down on the system which is paramount if you are using smaller, lightweight equatorial mounts. 


We have also developed a range of matching accessories to compliment the Horizon® 72ED. The first important accessory for imagers is the field flattener. This has been specially designed to work perfectly and compliment the Horizon® 72ED optics. This has a reduction factor of 1.0x which means it won't affect the focal length or focal ratio of the imaging system. By using our 1.0x field flattener, you can rest assured you will have a lovely flat field each and every time. The field flattener also features a rotator with locking knob so you can ensure your camera is at the right orientation each and every time. A comprehensive, easy to follow instruction sheet is included on how to fit the flattener to your Horizon® 72 ED.

The other fantastic accessory is the all new RVO Horizon® Guide. This is a high quality 50mm finder/guidescope that comes complete with a vixen clamp, 24mm illuminated crosshair eyepiece, 1.25" & T2 connections, ring system with 6 point delrin tipped adjusters complete with a high quality indexed helical focuser.

The retractable dew shield will keep a certain amount of dew at bay, but some nights will require a heater system to fully elimiate dew. Our RVO bands are perfect for the job. These high quality made bands simply wrap around the outer edge of the OTA close to the front element and gently heat the glass up just past the dew point. The bands have an elasticated velcro strap for a snug fit. All complete with either an integrated controller to work with any 12v power source, or an RCA jack for use with all dew controllers.

Our RVO Horizon® 72 ED OTA goes perfectly with a wide range of equatorial style systems. We recommend the iOptron SkyGuider Pro and  Star Adventurer. Due to the compact size and lightweight design, this is the perfect travel scope with a good tracking mount. The included bar makes it compatible with all standard equatorial mounts with a vixen style saddle.
