Especially difficult jobs such as focusing on a planet can be a real challenge. This helical focuser elegantly overcomes the problem. You need to do nothing more than to connect it to your existing focuser. The Focuser has A Fixed Orientation A further advantage is that the accessories, like a camera, do not rotate with the focuser. Therefore the orientation of the image remains unchanged. Via the optional adapter T2i-T2i ( Asin:B01NCS8RW6 ), the focuser can be easily attached to any male T2-thread, so the connection to your telescope becomes child's play. Setting scale - for finding the optimal focus position again A graduated scale always shows you the focus position you have just set. Once you've found the perfect point of focus, then you just need to remember this setting on the scale - you will then always be able to find it in future. The scale itself is similar to the millimetre markings on a ruler, but each marking here moves the focuser by only around 0.05 mm. Sharper focused Planets Via The Helical Mechanism Once the helical focuser is attached, simply turn the focusing knob with Anti-slip texture - which you can control easily even with gloves on in winter. The rotating mechanism allows very smooth and continuous focusing, and without any play. Adjustment Accuracy: 0.05mm The accuracy can reach 0.05mm, 10mm focusing stroke, and more precise focusing. Will meet your need for precise focusing during photography or, lightweight and portable, it's more convenient to carry and use. Brass Ring Design 1.25" accessory collar with brass compression insh to prevent the marring of your telescope accessories, will not scratches your expensive eyepiece or zenith mirror, safer and easier to use.
