Trial period

We are so confident in our CCD cameras that we offer a 30 day trial period. If you are not satisfied for any reason with your purchase of a CCD camera, you may return it within 30 days for a full refund, on the condition that it is in it's original packing and is not damaged. All cameras are tested before despatch and upon arrival. If the camera is not in the same condition as it was when it was dispatched, it will be returned to you, at your expense, and no refund will be given. Our decision is final.

Cancellations of custom built products

Some of our products are currently only built to order. This means that there is a period where we have already invested in materials and tools but the customer still has no product. The customer may cancel their order without penalty within 1 week of placing the order or 45 days after the scheduled shipping date has expired (if we are late). The customer may cancel the order at any other time without financial penalty but the refund will only be issued once the ordered item has been re-allocated to another buyer or 45 days has passed.


All new cameras are covered by a 24 month warranty against faulty materials or workmanship as per EU regulations. Modified cameras are guaranteed against workmanship and materials of the modification for 12 months, please be aware that despite the items being brand new, modification voids the original manufacturers warranty. While we will carry out modifications of your own equipment, due to the inherent risk in modifying complex electronics, we accept no responsibility for losses directly related to the modification. By entering into an agreement for us to modify your camera, you accept that it is at your own risk.


We ship worldwide. All items are sent via recorded & insured shipping. Depending on stock levels delivery may take up to 14 days within the EU and up to 30 days internationally. It is your responsibility to check the condition of the package upon arrival, if it is damaged or has been opened, do not accept it. All items are thoroughly tested before shipping, in order to clear up issues with shipping it is essential that you do not accept damaged packages. Free shipping does not apply to special offer products.

Rebuilt cameras and payment

By placing an order for a rebuilt camera such as our Ultimate series there are special requirements. A customers camera shall be sent in for a rebuilt entirely at the owners own risk. JTW Astronomy is not responsible for damage due to the inherent risks of rebuilding existing hardware. In the event of a cancellation we will return the deposit and camera to you with no charges provided that rebuild work has not already begun. Once the camera is in process the deposit is no longer refundable, the camera will be rebuilt to its original specification and shipped back to the customer. We will not replace the camera with a new or refurbished model in the event of a customer cancellation. If the cancellation is deemed to be required by JTW Astronomy, there will be a full refund of the deposit and a new camera shipped out to the customer.
