Collimating the secondary mirror did not help. In the end, I tried to collimate the primary mirror using a cheshire. This was the wall projection of the 6 inch telescope with a laser with DOE attachment after trying to collimate the telescope traditionally using a cheshire and a artificial star only.
Cheshire collimation eyepiece – the classical collimation tool for Newtonians and Refractors. The Cheshire eyepiece has a small pinhole to look through and a crosshair eyepiece at the opposite end. Light enters the system through a porthole on the side and is reflected diffusely into the telescope by a
A Cheshire eyepiece is a tool for alignment of the optical axes of the mirrors or lenses in a telescope. Shape and position of various elements of the image, including a crosshair with most modern Cheshire eyepieces, enable an assessment of the optical collimation.
The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1in focusers or diagonals.Alignment is easy using the small opening on one end and thin cross hairs at the other end.
The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1?” focusers or diagonals. Alignment is easy using the small opening on one end and thin cross hairs at the other end.
SIMPLE INSTRUCTIONS ON COLLIMATING WITH A LASER 1. Primary mirror must have some form of centermark. Inexpensive lasers offer no advantage for collimation over a low-cost collimation tool like the common sight tube + cheshire collimation Eyepiece (which might work better).
Cheshire Eyepiece. The Cheshire eyepiece is the simplest telescope collimation device. There are plenty of makeshift solutions, like the film canister with the hole in the cap, but the best guide for making a decent one along with all the underlying theory can be found here.
54 €. Takahashi Cheshire collimating eyepiece for Epsilon astrographs, 1.25″ / 31.8 mm. When coupled with Takahashi Sight Tube (TKA00442) allows for a precise collimation of the Takahashi Epsilon astrographs.
Cheshire collimating eyepiece for accurate alignment of any Newtonian reflector telescope mirrors, ideal for ensuring the best optical alignment. Accurate collimation is essential for ensuring the best performance from reflector telescopes, this quality easy to use Cheshire eyepiece is the
Refractor Collimation Newtonian Collimation. Collimating your refractor is quick and easy when you use this 1.25″ Cheshire collimating eyepiece.
The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1?” focusers or diagonals. Alignment is easy using the small opening on one end and thin cross hairs at the other end.

Trust the collimation eyepiece over the laser. Physical collimation (using at least a sight tube, which is what your collimation eyepiece is, and a Cheshire eyepiece) is the only foolproof way of collimating a telescope. Here is a device which combines sight tube and Cheshire, though the little
