Extension Tubes from TS
Different telescopes can have very different back focus distances. In most telescopes the focal plane is deliberately moved further out, allowing users to attach cameras and other accessories more easily.
Refractors always have a rather long back focus since they are usually used with a star diagonal or erecting prism.

The Problem:
As a result of this you often cannot directly focus the telescope if you do not use it with the above mentioned accessories. You would have to move the focuser further out, but you reach the end of the focus travel before reaching a focused image.

The Solution:
TS Optics extension tubes bridge the gap between the focuser and the focal plane. They are the ideal solution whenever the focus lies further outside than you can reach with the focuser.

The eyepiece is clamped firmly but without scratches through a brass compression ring. The advantage is that eyepieces are held more securely and the risk of the eyepiece being tilted out of the optical axis is minimized.
The extension tubes are machined from solid aluminium. They are black anodized. The 2" barrel has a safety undercut to prevent the extension tube from dropping out of the focuser accidentally.

2” Reduction adapter, 2” to 1.25” - 1.25” accessories for 2” focuser

An Omegon 2" reduction adapter allows you use 1.25 in. eyepieces in a 2 in. focuser. A compression ring centers the eyepieces and protects them “from damage. The adapter has a small length (10mm), allowing you to also use focusers with a short focus travel.

The advantages in a nutshell:

  • reduction from 2” to 1.25”
  • suitable for all 1.25" eyepieces
  • side lock screw
  • eyepieces are held gently in place by compression ring

Omegon 2" helical focuser - sharper planets in any telescope

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 Omegon 2" helical focuser is quick and straightforward, and you will then always be able to find the perfect point of focus.

The advantages in a nutshell:

2" helical focuser designed specifically for astrophotography
fits onto any 2" focuser
improves focusing precision
approximately 0.1mm focusing precision with 42mm of travel
comes with a M48 thread for your camera
The screw-less focuser for your telescope - it simply slides in

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.

Suitable for all 2" focusers

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.

Sharper focused planets via the helical mechanism

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.

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 0.1 mm. What about that for precision?

M48 thread for your camera

The accessory side of the focuser has a M48 thread for connecting your camera.

Our expert comment:


There are appropriate adapters for mating the M48 thread to the bayonet fittings of the various camera manufacturers. For example, the Skywatcher M48 Ring to EOS Bayonet

Alternatively, there is a flat adapter combination: T2 with Omegon M48 threaded ring

To connect an eyepiece, you will need the following adapter: Omegon M48 thread to 2 inch adapter
