Navigating Tariffs: Due to the current volatile tariff environment and associated logistics challenges, O'Telescope is unable to fulfill shipments to the United States. Orders submitted with a U.S. shipping address will be refunded, with the payment gateway transaction fee deducted. This restriction does not affect BackyardEOS or BackyardNIKON, which remain available as digital downloads.
Inventory closeout sale, everything must go. Up to 35% off. Some conditions apply.
We are closing our inventory side of the business and focusing solely on software - going back to our roots so to speak. No store coupons required, all prices have been marked down. First come, first served, until quantities last. We are no longer placing orders with manufacturers. Absolutely no rain checks. We reserve the right to cancel and refund orders at our sole discretion. We do our best to maintain our inventory accurate, but mistakes do happen, if you purchase an item that is no longer in stock, you will be refunded. The sale does not apply to some higher-end items such as 10Micron. Prices subject to change without notice. ALL SALES ARE FINAL.
Occasionally, we find a box under a box under a box in the back of the warehouse with hidden treasures, and when we do, we add these items on the site, so even though you may not find what you're looking for today, it could automagically appear next week.
