you looking for an inexpensive focuser that is as high-precision and
backlash-free as a Crayford? That is exactly what the Omegon 2" Helical
IF focuser provides. The high-precision mechanics ensure very sensitive
and precise focusing. The inner focusing mechanism also means that this
focuser does not rotate attached accessories, but raises and lowers them
- just like an elevator.
- helical focuser with inner focusing
- 30mm focuser travel / 70mm focuser length
- precision focusing
- inner tube does not rotate
- large, grippy focus wheel - also great when wearing gloves
What makes a helical focuser a viable alternative?
a Crayford focuser, the helical focuser design has a large focusing
wheel. This means it is also very easy to operate in cold weather when
wearing thick gloves. You don't have to fumble for it in the dark as it
is easily found almost immediately. The design means a helical focuser
is lighter compared to other focusers, and this can be crucial when you
are trying to balance the telescope. This helical focuser lets you focus
precisely. It also requires less maintenance than a Crayford focuser,
since there are no ball bearings and no need to adjust it.
Your accessories will remain right where you want them
simple helical focusers have the disadvantage that they rotate during
focusing, which means that your accessories also rotate. The Steeltrail
helical focuser is designed completely differently: The inner 2" barrel
moves in and out with millimetre precision and your camera or eyepiece
will always remain exactly in position.
Everything stays secure: enormous carrying capacity
helical focuser can carry a heavy eyepiece such as a huge 31mm Nagler,
or a hefty camera with absolutely no problem. It can take virtually any
accessory that you wish. This enormous load-bearing capacity is inherent
in the design, meaning the focuser tube cannot slip.
Simple adaptation to a Newtonian telescope
a suitable adapter to the focuser via an 80mm dovetail ring. Many
amateur astronomers have a Skywatcher telescope and want to upgrade it.
Up to now they had a problem however: there was no suitable adapter
available for Skywatcher dimensions. But now our optional Omegon adapter (not included in delivery contents) lets you attach your new focuser to your Skywatcher telescope in only a
couple of minutes.
Omegon Steeltrail focusers
We offer Omegon Steeltrail focusers in three different versions:
- Crayford for Newtonian telescopes
