When the focusing range of your telescope is insufficient, this sleeve extends the optical path by 30 mm. So you can easily reach the correct focus position for sharp images.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to the filter thread on both sides, you can use the sleeve not only with eyepieces and cameras, but also with accessories such as flatteners and reducers that require precise spacing. By combining several sleeves of different lengths, you put together a flexible solution for your setup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The extension sleeve is made of light and sturdy black anodized aluminum and fits into any 1.25\u2033 socket. This makes it an indispensable accessory for both visual observation and astrophotography.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Application<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Omegon 1.25\u2033 Extension Sleeve 30mm is ideal for correcting focus problems, achieving the correct image scale and setting the required backfocus when using flatteners and reducers.
