About Explore Scientific Extension Ring Set

It's time to enhance your photography and videography experience with the M48x0.75 Extension Ring Set, Black by Explore Scientific. This set includes five extension tubes, ranging in length from 30mm to 5mm, each equipped with an M48x0.75mm thread connection. These tubes are expertly designed to adjust the distance between your camera and the focal plane of your telescope or corrector/field flattener, providing you with the flexibility to capture your desired shots.

Each individual tube in this set features both an internal and external M48.0.75 thread, also known as the large T2 photo thread or 2.0-inch filter thread. This design allows for the use of camera-specific bayonet adapters or color and nebula filters, enhancing the versatility of your equipment.

The set includes five distinct tubes with steps of 30, 20, 15, 10, and 5 mm, providing a range of options to suit your specific needs. The larger free inner diameter of 45.0 mm effectively prevents undesired vignetting of the camera sensor, ensuring your images are clear and unobstructed.

With an outer diameter of 50.65 mm, these extension tubes can be mounted directly in any 2-inch diameter eyepiece adapter. Made from black anodized aluminum, these extension rings are not only durable and lightweight but also resistant to corrosion and wear, promising longevity even with frequent use.

In essence, the M48x0.75 Extension Ring Set, Black by Explore Scientific is a professional, high-quality, and reliable choice for photographers and videographers seeking to enhance their equipment and capture the perfect shot.
