RST-135
rst135_03.jpg

The main body weight is only 3.3 kg.

Its ultra-compact body makes it possible to load "13.5kg" without weight.
If you use the optional weight shaft and weight together, you can load up to 18 kg!

 

The main body has a built-in home sensor, and the setting work efficiency such as alignment is very high. There is also a GPS function, which is very convenient for expedition photography regardless of domestic or overseas! It is also a dual mount that can be used as a German equatorial mount and an altazimuth mount.

Ultra-compact body that fits in the palm of your hand. Body weight is 3.3kg

It drives powerfully without the need for a balance weight. The weight that can be loaded when not using weights is 13.5 kg. A 10 cm class imaging system can be installed with plenty of room. The declination side can withstand a certain amount of imbalance, so you don't have to worry about parallelization, which is difficult to balance. (The photo shows two Redcat51s installed in parallel.)

The optional weight shaft is 18mm in diameter. It is compatible with Takahashi's balance weight, so those who have it can use it. To install, remove the metal cap from the main unit and screw it in. The length is 200mm.

Please use PoleMaster for polar axis setting. A dedicated adapter is included, so it can be used only with the main unit.

The declination head has 35mm pitch M8 screws (Takahashi standard) arranged as shown in the left figure.
It also indicates the orientation of the lens barrel setting. A diagram is printed. Install the lens barrel with the tip pointing in the direction of the arrow to set the home position correctly. It's nice to see such attention to detail in the product.

The included controller "Hubo-i SE" is lightweight and easy to hold. A combination of a large LCD screen, an easy-to-press cross, and a numeric keypad. Works with PC and star map software via USB cable or WiFi communication.

The LAN cable that connects the controller and the RST-135 main unit is a type with a protective cap at the tip and a cover that does not bend at the base. Such parts also have a sense of luxury and consideration for the user.

A fine screw is used for the altitude adjustment screw. Since the screw pitch is fine, it is possible to perform more precise adjustment work. (Updated from May 2020)
If you have an old specification product, we will introduce an upgrade kit, so please contact us.

The bottom of the RST-135 has M8 screw holes at 45mm intervals as standard (upper left photo), but a 3/8 inch adapter (lower right photo) is included as standard.

Optional half pillars are available for several types of tripods. The figure on the right is set on the K-ASTEC PTP-C22 carbon tripod half pillar. Other options include Gitzo3/4/5 series, iOptron tripods, and Avalon tripods.

rst135_014.jpg

The half pillar comes with a top plate like this that is fixed with 45mm pitch M8 screws on the bottom of the RST-135.

Body weight is 8.5kg

 

Despite this, the monster mount allows a maximum loading weight of 50kg.

Even a weightless machine can carry 30kg and easily move the EdgeHD14".


The main unit has a built-in home sensor, and the setting work efficiency such as alignment is very high, and there is also a GPS function, so it is very convenient for traveling regardless of domestic or overseas! It is also a dual mount that can be used as a German equatorial mount and an altazimuth mount.

It drives powerfully without the need for a balance weight. The loadable weight when not using weights is 30 kg. A 35 cm class Cassegrain mirror can also be easily operated. If weights are used together, a maximum of 50 kg can be loaded.

There are two types of optional weight shafts. In addition to the dedicated balance weight for 30mm diameter and 300mm length, you can also use the balance weight for Skywatcher EQ8, which has a slightly larger inner diameter.
(EQ8 weight shaft is 31.8mm)
Another 1.5" diameter by 11.8" length is compatible with ADM weights.

The declination head has a 35mm pitch M8 screw (Takahashi standard) in the center as shown on the left. There are also four M8 screw holes and four 1/4 inch screw holes on the φ76.2mm. It also indicates the orientation of the lens barrel setting. A diagram is printed. Install the lens barrel with the tip pointing in the direction of the arrow to set the home position correctly. It's nice to see such attention to detail in the product.(Dimensional drawing)
