Early Diagnosis of SSc in the General Rheumatology Clinic - Pilot

The goal of this observational pilot data acquisition study is to establish if target users can obtain diagnostic quality images in the clinic, from participants with Systemic Sclerosis (SSc), and SSc spectrum conditions. The main questions it aims to answer are: * Can a range of healthcare professionals, including non-specialists, use the capillaroscopy image acquisition system to take high quality images that can be used to create a clinical report? * Can the investigators collect user and patient feedback on the usability of the capillaroscopy system, to help develop the software and to develop the clinical report * Which microscope light source, from four different light wavelengths is better to see the blood vessels in skin with more melanin content. Participants will be asked to attend a single clinic visit where they will undergo a brief, non-invasive nailfold capillaroscopy examination, using the software-guided capillaroscopy system. Participants and rheumatology healthcare professionals will be invited to take part in one or more focus groups and interviews, to collect feedback and to contribute to the development of the image acquisition software and the clinical report.
