Customer Support: Contact Info, Average Response Time

The best way to contact us is through our support platform, via the link below. We offer assistance in French, English, German, and Japanese.

Our team of experts based in Europe (South of France) is very responsive and will take the time to answer all your questions and help you out if you have concerns regarding your UNISTELLAR products.

During business hours, which are Monday to Friday from 9 AM to 6 PM CET/Paris time, we aim to reply to all non-technical queries within 48 hours when possible. For technical requests, it can take 72+ hours (excluding weekends and official holidays**). 

We do not have any direct phone lines set up at the moment as we are still a small business with limited staff capacity, however, we ensure that our team provides the best (human) customer support possible via our helpdesk platform. In certain cases, we might send you a text (if you are in the US) or schedule a phone or video call to resolve complex issues (after having received pictures and/or videos from your side when required).

Important: We kindly ask for your patience as we address your request. For privacy and efficiency, troubleshooting is handled directly through our support channel, not via social media or any staff personal/internal emails. Please note that sending multiple requests won’t expedite the process, as we handle inquiries in the order they are received and monitor response times closely.

Note: if you require any technical assistance, please include the serial number of your telescope systematically

*If you didn't receive an immediate automated confirmation of the receipt of your request (within 1-5 minutes), it means there is an issue out of our control. Please don't forget to check your junk mail or spam folders in case our messages have been blocked by your SPAM filter. Also, please keep in mind that, in addition, there can be some delays in response, depending on your time zone. Sometimes, we can respond when it's a deep night for you, and vice versa. Thank you for your understanding and patience.
