Take your astrophotography to the next level with the T-Adapter, specifically designed for EdgeHD 9.25"", 11"", and 14"" optical tubes. This indispensable accessory threads seamlessly onto the rear cell of your EdgeHD telescope, providing a secure and stable connection for your 35mm Dslr camera. By attaching your camera to the prime focus of your EdgeHD telescope using this T-Adapter, you can capture breathtaking terrestrial images and short exposure lunar and planetary photographs with unparalleled clarity. Moreover, this T-Adapter is not just limited to short exposure photography. It's also perfectly suited for long exposure deep-sky photography when paired with a separate guidescope, allowing you to delve into the mysteries of the cosmos like never before. Please note that both a T-Adapter and T-Ring are required to mount a 35mm Slr camera to your telescope.
