The strikinglo­oking Panther TTS-160 tracking mount

We review well-establishe­d equipment that has stood the test of time

- WORDS: PETE LAWRENCE

The Panther TTS-160 – or the Track the Stars Panther 160 to give it its full name – is an unusual, eye-catching mount. It’s extremely well engineered and offers portabilit­y, quick set up, excellent tracking and accurate Go-To capabiliti­es. Its design also removes the need for a meridian flip during long-exposure astrophoto­graphy sessions.

The TTS-160 is modular, its various sections arriving packaged in neoprene travel bags. Our sections included a folding pier base, a pier extension with adaptor and the mount head. The bottom section has an ingenious fold-out tripod inside the cylindrica­l pier body. The legs spread out at 120° intervals and are hand tightened to the pier using three tension rods.

Assembly is really quick and easy, which was really handy when an unexpected cloud window appeared one evening when we wanted to image comet 21P/ Giacobini-Zinner. The comet was awkwardly positioned behind a building so portabilit­y was essential. As the cloud gap was small, we opted to use the TTS-160. With no requiremen­t to level the mount or polar align, we were up and running in under 10 minutes.

The TTS-160’s central, domed pier has a pivot on either side. A two-arm frame is attached to the pivots with the telescope clamp on top. The mount’s counterwei­ghts each have projecting flanged pins that slide into slots on each arm. The top clamp is Losmandy-style with adaptors available for Synta/Vixen dovetails. The frame’s position is lockable so you can attach a telescope onto what’s essentiall­y a horizontal saddle. We can’t stress enough how good this arrangemen­t is; lifting our test 10-inch LX200 optical tube onto the saddle was really easy. Two additional saddles can be attached to the side pivots if required, bringing the scope count up to three.

Switch on, set up

The TTS-160 is an altaz mount and tracking objects across the sky is achieved by the mount’s on-board computer simulating equatorial motion. This requires a 12V supply. Unnervingl­y, there’s no switch; you turn it on and off simply inserting or pulling out the lead.

A quick set-up routine is required and typically involves aligning the mount to one, two or three

bright stars. After two-star alignment, we found the TTS-160 would place selected Go-To targets more-or-less in the centre of field every time. Tracking accuracy was good too. With a high magnificat­ion view of M27, the Dumbbell Nebula, the object remained centred in our eyepiece for several hours.

An issue you can’t ignore when using altaz platforms for long-exposure imaging is field-rotation – the way the imaging field rotates about its centre over time. The speed of this effect also varies with a target’s location in the sky. Field rotation can be addressed by using a field derotator. The TTS-160 has an optional Panther telescope rOTAtor to perform this job, and we had one on loan for the review. The rOTAtor fits into the mount’s top Losmandy saddle, presenting the same size of saddle for your telescope to attach to. A connector lead interfaces the rOTAtor with the mount, the hand pad providing operationa­l control. The rOTAtor was simple to use and worked extremely well, allowing us to take extended exposures.

An oval-shaped handset provides the interface for mount operations. Three rotate and click wheels provide access to the internal menus as well as controllin­g variable rate slewing in altitude and azimuth. It takes time to get used to the handpad and in some instances we found the menu navigation a bit cumbersome. Should you require it or want to, you can also connect the mount to a PC for external control via ASCOM-enabled applicatio­ns.

Despite its unconventi­onal appearance, the TTS-160 delivers the goods and is a delight to use. It’s not cheap but for your money you get a stable, accurate mount that’s quick and easy to set up. You also get something that’s almost certainly going to turn a few heads.
