Product description

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

( 5 / 5 )

Not only it looks great but it also feels great! It is made on a very high level. The threads are very precise and rotation of the focuser goes very smoothly. It is very interesting that it is practically the only 2'' focuser on the market. I found one but is dedicated so not usable if for example You use Canon camera or so. Let's be honest,..it is not cheap but considering the quality it offers the price is ok! It is beautifully anodized as from outside same from inside. No reflection when pointed toward some stronger light source although I would prefer even more mate finish from inside, that said, I meant even less reflective than it actually is. All in all great thing for precise focusing. I am very happy with it. Just bear in mind to get some spare rings of appropriate size in case You need focus shifting. All in all HIGHLY RECOMMENDED, good job Omegon!!
