Product Description

Astromania Telescope Focuser 2 Inch, Double Telescope Helical Focuser 2inch

Whether you're using a telescope focuser 2 inch setup with a DSLR or telescope eyepiece, this helical focuser telescope accessory ensures critical focus is achieved every time for giving the precision and stability needed for sharp focused deep-sky images
This 2inch helical focuser fits onto any 2 inch focuser for offering universal compatibility with many telescopes; This double helical focuser connects seamlessly to your existing focuser regardless of whether using astronomical telescopes with 2" focuser
This focuser delivers approximately 0.1mm focusing precision with 39mm of travel dramatically improving focusing precision over standard focusers. Such fine control is critical for high-magnification astrophotography during astronomical observation
The generous 39mm of travel allows to reach focus with a wide variety of cameras eyepieces and barlow lenses; Helical focuser makes it simple to find perfect focus even when using focal reducers or field flatteners that require extra back-focus distance
The telescope accessory side of the telescope focuser has a M48x0.75 male thread for connecting DSLR/mirrorless cameras with T-ring for making it a true astrophotography helical focuser via M48-T2 telescope adapter that is not included (ASIN: B01DIRJ72I)
Helical focuser 2 inch unit is suitable for both refractors and Newtonian telescopes and is also particularly useful with Schmidt Cassegrain telescopes; Widely compatibility makes it a top choice as a telescope focuser as choice for astronomy enthusiasts
The rotating mechanism allows very smooth and continuous focusing and without any play for ensuring that once focus is set and it holds firmly in place; It is essential for both visual observation and long-exposure guiding
The precision-machined double helical focuser design adopts black aluminum alloy for long-lasting using; It works perfectly with a M48-thread camera adapter or a simple 2 inch eyepiece, making it an essential upgrade for astronomy enthusiasts

One of the biggest challenges in photographing the Moon and planets is precise focusing of the object. Not all telescopes are well equipped for this. Equipping your telescope with the Astromania 2" helical focuser is quick and straightforward, and you will then always be able to find the perfect point of focus.Many telescopes have a focuser which does not allow very precise focusing. Especially difficult jobs such as focusing on a planet can be a real challenge. This helical focuser elegantly overcomes the problem. It is suitable for both refractors and Newtonian telescopes, but is also particularly useful with Schmidt-Cassegrain telescopes. You need to do nothing more than to connect it to your existing focuser.The helical focuser has a 2" barrel. This allows it be inserted into the focuser just like an eyepiece. Its separate focusing mechanism now takes over the job of precision focusing.Once the helical focuser is attached, simply turn the oversized focusing knob - which you can control easily even with gloves on in winter. The rotating mechanism allows very smooth and continuous focusing, and without any play. Your new focuser does exactly what you tell it to.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 0.1 mm.There is a flat adapter combination: Astromania T / T2 Male Thread 48mm to 42mm Female M48 to M42 Telescope Adapter.
