About this product
Supplied with pre-installed Rowan Belt Mod Upgrade.
A Rowan Belt Mod upgrade replaces the HEQ5 Pro's original spur gear drive train with timing belts. This reduces spur gear errors, which reduces tracking errors. Slewing is also much quieter (the 'grinding' noise that regular spur gears produce is significantly reduced). The pulley ratio is the same as the factory gears so Sky Watcher SynScan hand controller functions are unaffected.
We also offer the pre-fitted Rowan Upgrade together with a clean & regrease. The wheel and worm gears are removed, cleaned, regreased then refitted. Backlash is adjusted to the minimum necessary to function. (Mounts using the Worm & Wheel system require some backlash). Is a clean and regrease necessary for a new HEQ5 mount? Probably not. The days when you might find swarf and thick black gluey grease in a HEQ5 are long gone but we are still occasionally asked for a clean & regrease so we offer the service. Over 90% of the improvement comes from the Rowan upgrade alone.
The HEQ5 Pro mount is considered by many to be Sky-Watcher's 'sweet spot'. A mount costing less than £1k with an impressive combination of ease-of-use, stability and tracking performance. It is probably the mount most recommended to someone wanting to begin astrophotography.
The SynScan computerised handset's two-line illuminated LCD screen is easy to read and navigate. One-star, two-star and three-stars alignment routines are available and are easy to use. All work but three-star alignment is the 'gold standard' because it corrects for cone error. Once aligned, SynScan Go-To will automatically place objects in the eyepiece field-of-view wherever they are in the sky. Think Sat-Nav for astronomers! You can also control the mount from a laptop or desktop PC via the handset's RS-232 serial port (cable available separately) or, even easier, connect the mount directly using a Lynx Astro EQDIR adapter.
Similar to Sky-Watcher's larger EQ6 Pro, the HEQ5’s counterweight shaft slides neatly into the body of the mount for easy storage and transportation. It also has a built-in polar alignment scope which makes it easier to align the polar axis of the mount to the Earth’s axis of rotation (whilst not strictly necessary for Go-To pointing accuracy, tracking is improved if the mount is polar-aligned). Looking through the polar scope you will see a graphic that enables you to offset quickly and easily from Polaris to the true north celestial pole.
Compatible with EQMOD using a Lynx Astro EQDIR adapter.

I was looking to upgrade my EQ5 pro to HEQ5pro since adding extra kit had increased the load somewhat. Several suppliers do a Rowan upgrade, but I finally chose to go with FLO. I placed the order on a Monday morning and was amazed to find it was ready for shipment on the Wednesday. Fantastic upgrade to EQ5 - the HEQ5+Rowan is so much smoother and quieter and of course nearly doubles the maximum load over the EQ5. Looking forward to much more reliable guiding from now on.
Great service from FLO.
Additional payment for Regrease Option

When I first received my HEQ5 mount, there was quite a bit of friction in the RA and DEC movements. I returned the mount for the Regrease option. The mount now moves freely. Along with the Rowan Belt upgrade, I would recommend also purchasing the Regrease option.

I would have given 5 stars but I've experienced cloudy skies since receiving the mount. Because of that, I haven't been outside to gauge the mount's performance.
Go figure. I will say that the shipping was fast. I mean FAST! I live in the States, and within one week the mount arrived here in Michigan. I purchased the mount with the Rowan Belt mod installed. It is very quiet. Also, even with the extra cost of the mod and figuring in shipping, it was at a lower cost than if I had purchased it from a U.S. outlet.
I would recommend First Light Optics.

This is my first mount with any sort of tracking and I'm seeing things I wasn't even getting close to before. I wish I'd bought one years ago! As you would expect with a Sky-Watcher mount it's solid and accurate, without being too heavy to move in and out of the house. Great service too from FLO who answered all my questions very promptly.
Wonderful Mount very quiet

Bought this a few days ago delivery from FLO was as always excellent. The belt drive upgrade really makes it quiet compared to noisy gears. Looking forward to many hours imaging ...once the included clouds disappear
