Product description: Omegon premium Moon filter - to ensure that your lunar observing is fun Does the Moon appear far too bright when observing it through your telescope? The Omegon Moon filter reduces the brightness and increases contrast. It screws easy into your eyepiece, permitting relaxed observing and stopping the Moon from dazzling you. The advantages in a nutshell: Omegon neutral density filter - tones down moonlight for more comfortable observing neutral image - the Moon retains its natural appearance high contrast - discover thousands of craters and fine structures for your eyepiece - fits onto any 2" eyepiece with a filter thread The Moon is too bright - tone it down a bit The Moon can be so bright that you can easily read a newspaper by its light at night. But anyone looking through a telescope will note just how bright the Moon really is. It often irritates the retina and dazzles the eye in unpleasantly. No wonder - the full Moon is 25,000 times brighter than the brightest star in the night sky. So having a neutral density filter is definitely an 'ace up your sleeve' when observing the brighter lunar phases. Filter with 25% light transmission This filter is ideal for smaller and medium-sized telescopes up to a diameter of 150mm. The 25% light transmission reduces the brightness of the moonlight, allowing you to observe the Moon at any time - in comfort and without glare. Polished glass for a clear view You are purchasing a first class product with the Omegon Moon filter - a polished glass filter held in an anodised aluminium mount. The filter glass has been ground and stained throughout the entire glass volume. This avoidance of using a superficial coating means that it cannot wear out, even after many years of use. A Moon filter belongs in the eyepiece case of every amateur astronomer. But, above all, it is a must for comfortable lunar observing.

TS Optics Non rotating helical focuser with M48 connection A true helical focuser like this works like a camera objective - when you turn the focusing ring, neither the lens nor the camera (or eyepiece and diagonal) will rotate. The only motion is in and out. The advantage of this helical focuser is the fine adjustment, possible in part due to the fine pitch of the focusing ring's thread, and in part due to the large diameter of the ring. In the case of this helical focuser, virtually backlash-free movement and graduated markings on the focusers allow repeatable return to the focus point simply by noting the focus position reading. Advantages at a glance no rotation of the diagonal or camera - the only motion is in and out precisely adjustable limitedly self-locking wide focus range: 40 mm 51 mm minimum height, 91 mm maximum height easy adaption to the telescope tube and the camera good solution for telescope or objective self construction M48x0.75 (2" filter) threads at both sides, with all adaption possibilities generous clear aperture of 45 mm also suitable as variable M48 extension 51 mm to 91 mm for the perfect working distance two screws for locking the drawtube Wide focussing range and short length The Helical focuser has a wide focussing range of 40 mm, but it is very short, with a minimum height of only 51 mm. So you can use the focuser on telescopes or telephoto lenses with little space to the focus point, like Newtonians. Accessories This focuser is not suitable for heavy accessories, it will tilt. The main use is with small CCD cameras for planetary photography, 1.25" eyepieces and lightweight 2" eyepieces. Delivery contents Helical Focuser with 2 locking screws
