RB-Focuser Merlin 3.0 Electronic Focus Motor

We present the following evolution  of our  innovative autofocus solution for astronomical telescopes, designed by and for astrophotographers. Our new flagship the   RB-Focuser Merlin 3.0, completely made in Spain using in its entirety CNC machining process in Aluminum. Brings the ability to all hobbyists to get a high-end electronic focus motor with the best performance  that allows auto focus the  telescope without moving it to bright stars and with impeccable precision far above the well-known Bahtinov mask. 

More power, sensors and connectivity, the RB-Focus Merlin 3.0 comes packed with a variety of useful sensors including a digital thermometer,  Sensorless AutoHoming ™ and antennas that allow connection via bluetooth in order to reduce cables and weight in the image train, in addition to a Dual Core processor that performs autofocus tasks independently from those of refreshing data on the screen and internal functions, so always being asked to focus despite busy doing other calculations.

Manual control through a mobile APP, we stop using analog controls and old boxes with push buttons.  The RB-Focus Merlin has the option to connect with your mobile allowing people to focus even when they are doing visual or planetary.

Our Sensorless Feature  AutoHoming ™  Now without the need for sensors, it allows the telescope's focuser to be automatically calibrated in various directions, as before, if the focuser tube is accidentally moved or the tube is to be manually collected at the end of the session to put the equipment in a bag Don't worry about transportation, our ultra-precise home position auto-sensing system will return the tube to the last focus point applied by the capture program, which avoids position losses and the need to remember which is the tentative point of focus of the telescope. . In addition, through the innovative detection system by study of  magnetic fields  We will be able to determine if the focuser mechanism has the correct tension to avoid product slippage.

It has a resolution of 16000 steps per revolution or only  0.7 micron, it is on par with the best options available in the market, for a price that is affordable for all. In addition to clockwork precision, its DirectDrive ™ or direct drive technology avoids play problems in mechanical drives well known in other products and allows the telescope to be focused manually when a computer is not available. Additionally, we introduce our ultra-quiet motor system, InteligentSilentDrive ™, which actively adjusts motor force as needed while maintaining completely noise-free operation.  By working with the ASCOM and INDI standard, it is compatible with the most popular capture software on the market such as APT, SGP, NiNa, Voyager, KStars, EKOS and others. It comes with a simple controller that allows you to configure the product in a short time and adapt it perfectly to any route, regardless of the focuser that your telescope carries. All this technology presented in a small and discreet module of just 7 cm high and 280g.

We broke the myth that autofocusers are for advanced users with dedicated monochrome cameras, the product has been tested and is just as effective in dedicated color or DSLR cameras from the most basic to the most advanced models, opening the possibility to every astrophotographer with A telescope either reflector or refractor to fully automate your photography sequences.   

The integrated LCD IPS screen now with automatic shutdown, allows you to check the correct operation of the electronic focuser at all times, see the saved settings and monitor the movements you are making in real time without having to look up the value on the computer.

Products of this nature usually come with pages and pages of configuration packed with parameters, which makes the process of fine-tuning them very tedious and ends up taking astrophotographers away from the great advantage of having a self-focusing telescope. In view of this we have adapted the software to work with basic and easy-to-understand minimum settings.  by anyone related to the world of astrophotography without losing the functionality and control of more complicated devices, making once and for all one of the most advanced techniques in astrophotography available to all users.

We are not just another company, we are astrophotographers and we understand how difficult it is in itself to get into this hobby, so we are willing to help with any inconvenience and doubt that may arise when configuring the product, remote assistance and to the extent if possible we can even help you with the configuration and set-up at no additional cost.
