Introducing the brand new RVO Horizon® 60 ED doublet imaging refractor. The smaller, more compact version of the incredibly popular Horizon® 72 ED. Portability and quality of optics are key with this superb new telescope. It keeps the stunning optical quality of the Horizon® 72 in a smaller, lighter and more portable body ideal for grab and go rigs with mounts such as the Skywatcher Star Adventurer and iOptron SkyGuider Pro.

With the Horizon® range, quality control is very important to us. We are committed to guaranteeing that every single Horizon® scope leaves us in perfect collimation and in perfect condition. Every single Horizon® scope sold is thoroughly checked even down to each thumb screw on the scope to make sure all is well before shipping.
A In house Zygo test report is supplied as standard with the Horizon 60mm.
The interferometer is essentially a measuring instrument. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. From this, we can adjust the position of the test optic and the reference sphere to obtain a perfectly calibrated system. The more central the laser to the test optic and then on return, the better and more accurate reading and measurement we can take. This takes a lot of adjustment to get the best results from the optical surface. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. We will aim to provide 0.95 Strehl or higher.
The 60mm ED also features a CAA (camera angle adjuster). This means you can rotate your camera to get the perfect orientation without having to rotate the complete telescope. This will improve accuracy when switching between visual and imaging and vice versa. The focuser is made from CNC machining ensuring high quality and robustness whilst keeping the precision, ideal for the astrophotographer. The focuser on the Horizon® 60 is compatible with a lot of popular motorfocusers including the Pegasus FocusCube. The focuser also features a 10:1 fine focus knob enabling you to get the perfect focus, every time.
The main purpose of the Horizon® 60 is for widefield astrophotography. The focal length of just 360mm will provide a massive field of view with superb colour correction and sharpness thanks to the high quality doublet glass. If you are imaging very widefield targets, then there is also a matching 1.0x Horizon® 60 Flattener to ensure a completely flat field edge to edge. A full range of adaptors is available to get your camera perfectly spaced. The CAA can be left on the OTA to provide full rotation when using the flattener.
If you want to use this scope for visual, then you will need some accessories to go with it. We recommend a high quality 2" diagonal, finder and some eyepieces to get you going. If you are wanting to use this scope for visual work too, then please contact us and we can put a package together. Why not take advantage of the tack sharp optics for some breath taking widefield views of the stars!
One of the nice features of the 60mm ED is that we have designed the kit to make it usable straight out the box. We have attached a longer bar so you will can achieve a perfect balance every time, as well as a synta style finderscope base. This will accept most standard finders as well as our all new RVO 32mm Horizon® Guidescope.
The scope comes complete in a high quality hard travel case. There are additional cut outs in the foam to accept the 32mm Horizon® Guidescope too so you can comfortably house this in your case for safe travel and storage.
The scope is available as either an OTA only or a full imaging package paired with the Horizon® 60 1.0x Flattener and the all new 32mm Horizon® Mini Guidescope. Click here for the full package on our website.
