**Sirius Optics is still open for business. As the situation is changing on a daily basis, check our website for the most up to date information.**
We are currently dealing with a larger-than-usual volume of online and in-store sales, and while we endeavour to dispatch same-day, processing may take an extra 1-2 business days.

At this time, to ensure best health standards are upheld, we will not be allowing customers to handle binoculars, spotting scopes, and telescopes in the showroom
Visit this page for updates on the measures we are taking to combat COVID-19.

We would like to remind our new customers to please review our store policies regarding placing orders, change-of-mind, and order cancellation, before placing an order with us.
