Product Description

This product is designed to directly replace the handset in the Skywatcher Autofocuser kit and is the next step for our Focus RF unit, as this version has:

USB interface
Socket for our temperature probe
ASCOM focuser driver software
Software application to configure and control the focuser
Ability (with optional adaptor) to control stepper motor focusers as well as DC motors

It allows you to focus the telescope remotely from up to 20m away, without any trailing wires that will always wobble the telescope a little while you are trying to focus.

Extremely simple operation with 8 buttons arranged in 4 rows of 2. The top 3 left buttons turn the focus one way and the top 3 right right buttons turn it the other way. The buttons at the top are slowest, down to the fastest ones at the bottom. Buttons 7 and 8 select "Continuous" or "Step mode".

Power can be provided from our high quality Mains power supply

Specification:
DC Jack (2.1mm, centre positive) for 12V external PSU (not included)
Outputs via RJ22 connector
Reverse polarity protected
Operating voltage range: 9V to 14V
Current in standby: 28mA
Maximum motor drive current: 1A
Red indicator (slow flash) for power on
Green indicator for RF activity
Dimensions: 66 x 66 mm

Customer Reviews

10/10  Excellent device  Bought this along with a skywatcher autofocuser to fit to my Sky Mak 150 OTA fitted with a Vasco Ribiero Adaptor kit to do auto-focussing. The 4tronix Focus RFU connects in N.I.N.A. and it all works really well. I am able to perform remote autofocus in N.I.N.A and get a very good curve. Happy man.  (09/08/2023) Michael - Morpeth
