TS - Laser Collimator
A simple, quick and precise way to collimate your Newtonian telescope.

Laserneu.jpg (31129 Byte)

The TS Laser Collimator - the thumbscrew to the right is the on-off switch.

Newtonian Laser Collimator - 1.25" Barrel Diameter

A well made all metal laser collimator machined from 40mm massive aluminium.

Mechanical Quality
Since the Laser pointer itself has a very thin wall and is quite delicate the massive body of the Laser Collimator serves as protectice cover. Once aligned the laser will not lose its collimation. You still can collimate the laser itself using three alignment screws.

Barrel
The Newtonian laser collimator has a long 1.25" barrel and a machined rim for proper alignment. These very relevant parts of the laser's function are CNC machined.

Tips for Use
There are two situations that you should try to avoid.

One of them is to insert the laser at a slight angle to the optical axis of the telescope. This happens sometimes when you put in the laser from the side. For this reason we recommend to turn the telescope so that the focuser will face up. Then you insert the laser without using the locking screws of your focuser. The laser will then sit on its CNC machined edge.

The second thing to consider is the on-off switch. This is implemented using a thumbscrew. Once the laser is switched on please stop turning the thumbscrew! Damage might occur otherwise.

The New 45° angled viewing port

NEW! - 45° Angled Viewing Port For Easier Viewing From The Rear of the Telescope

Rear Viewing Port
The viewing port allows you to see the progress of collimation from the rear of the telescope. You will not have to use the old "trial and error" method.

The Laser Itself Can Be Collimated
You do not have to rely on the factory's precision when it comes to the laser's own alignment. If you should notice that the laser dot forms a small circle when you turn the laser in the focuser you can adjust alignment yourself. Just remove the cap at the rear of the focuser and use the three alignment screws for collimation.
Please note: You should be very careful when doing this. The laser itself has a thin wall and can be damaged if you exert too much pressure.

The 45° angled view port allows you to see the collimation progress from the rear of the telescope. Even large Newtonians can thus be easily collimated by a single person.

A Short Manual - How To Use The TS Laser Collimator:

Step 1: Collimation of Secondary Mirror (see right image)
After checking the orientation of the secondary mirror with your unaided eye just insert the laser collimator. Then use the collimation screws of the secondary mirror until the laser dot is centered on the primary mirror.

A center marking is recommended for this.

Step 2: Primary Mirror Collimation (see left image)
Turn the laser collimator so that you can see inside the 45° angled view port from the rear end of the telescope. Then use the primary mirror collimation screws until the returning laser dot hits the center of the laser.

As you can see the collimation of a Newtonian telescope becomes perfectly simple with the TS Laser Collimator. You can check and if necessary correct the collimation of your telescope within a few minutes.

As a result you will always observe through an optimized telescope for optimal performance.

Chesire Collimation Eyepiece


Chesire - with precisely machined rim

View through the Chesire collimation eyepiece in a Newtonian - you can see the slight miscollimation.	View of a slightly miscollimated refractor. Both rings should be centered.

Chesire Collimation Eyepiece 1.25"

The Chesire collimation eyepiece is the classical tool for Newtonian and refractor collimation. Light is reflected into the telescope through the 45° angled surface. When looking through the small porthole of the Chesire you will see the separate optical components and the reflections thereon. A perfectly aligned telescope will have all reflections centered around each other.

A crosshair at the front end of the Chesire helps to know where the center is.

The Chesire has a broad rim that is precisely machined so that it will sit in the focuser in perfect alignment - if this were not the case collimation would be imprecise.

For a refractor alignment is just as easy. You will see one reflection for each glass-to-air surface. If the telescope is perfectly aligned all reflections will be centered - in general such a perfect collimation is not necessary, though. It is enough if the reflections are inside one another, they need not be centered.

Binocular Viewers

Observing with both eyes means a significant gain in your eyes' ability to see faint details. At the same time you will be more relaxed and can observe for longer periods without straining your eyes. Binocular viewing is helpful both for lunar, planetary and deep sky observing.

A nice side effect is that negative effects of seeing conditions do no affect the image as much. When watching with both eyes objects seem larger than with only one eye.

The light is split 50/50 for each eye. Despite that you will not notice a loss in image brightness - the human brain is able to add the images seen with both eyes and even see more detail than would be possible with one eye.

TS Glass Path Correctors For Binocular Viewers

Binocular viewers often require lots of extra back focus. Many telescopes such as Newtonians and many refractors do not have sufficient back focus to accomodate binoviewers. For those cases we offer two Glass Path Correctors that will extend the focal plane further out and will allow you to reach focus in such telescopes.

Glass Path Correctors Move The Focal Plane Further Out So That You Can Use Binoviewers In Almost All Telescopes

Depending on which binoviewer you use the glass path correctors magnify the image by a factor of approximately 2.7x.

Ronchi - Eyepiece 1.25"

1.25" Ronchi Eyepiece - A Tool For Testing Telescope Optics

The Ronchi Eyepiece is used like a normal eyepiece. It is inserted into the 1.25" clamp of your telescope and then "focused" with the focuser. The only difference is that you look at the image from both sides of the focus.

You will see several "bars" that describe the surface of the optics. Theoretically perfect optics (even though we haven't seen such optics before) have perfectly straight ronchi lines. The lines can be curved, distorted, ..., always hinting to various different optical aberrations.

Warning: While it is easy for everyone to see optical aberrations with the Ronchi eyepiece a lot of experience is required to judge how strong those aberrations are.

The Ronchi eyepiece has 10 lines per mm.

Starway Transport and Storage Cases
available for many astronomical mounts, telescopes, ...

High Quality Transport Cases from StarWay

Starway transport cases protect your expensive and delicate optical equipment ideally. The cases are specifically made for particular instruments and thus fit the telescope perfectly.

For this reason we order each case for you specifically. This results in a slightly longer delivery time, but this way you can make sure that you get the best possible product to suit your needs!

A particular hard foam was chosen to protect the telescope from impacts and to avoid scratching the tube while at the same time offering best possible rigidity and a long lifespan.


The cases are kept shut using robust buckles. The buckles have locks for safety.	Several of the cases have rollers for easier transportation. All cases have handles.	The foam of each case (except models for self adaptation) is individually cut out for each telescope model.

Specifications:
- robust aluminium cases with reinforced edges
- individually cut-out foam available for many different telescopes or mounts
- hard foam for ideal protection and a long life-span
- several of the cases have rollers for easier transportation
- robust buckles keep the cases securely shut. They have locks for safety.
- excellent protection from mechanical shock as well as against moisture.

Scope of Delivery:
Each case has foam inside. The foam is either without cut-outs for self-adaptation or has cut-outs for a particular instrument.

A few more Examples:


StarWay case for Celestron C14	StarWay case for EQ6	StarWay case for 8" Meade LX90

Dimensions and Prices:

The list below shows the approximate dimensions of each case. The examples show instruments that are compatible. Often other instruments of similar size can be used as well.

The cases for self adaptation are filled with foam that you can cut out yourself with a knife. Cutting the foam is very simple and this allows you to individually adjust a case for your particular instrument.
