collimating AstroMaster 114
With a tube length of 46 cm and a focal length of 100 cm, probably the AstroMaster 114EQ is not a classical Newtonian but uses a fast (e.g. f/4) spherical primary mirror and a corrector lens built into the base of the focuser to reduce spherical aberration and increase the effective focal length (e.g. to f/8.8).
This is a variant of the Jones-Bird design of some custom telescopes.
There is some doubt about how well the corrector actually works in budget-priced telescopes.

Most collimation instructions (e.g. Seronik or Carlin) assume a classical Newtonian design.
Jones-Bird collimation is similar in theory but more complicated in practice.
In particular, the corrector hinders the use of a laser device.
Try a collimation cap; anything that fits a 1.25 inch focuser is fine.
You can even get decent results with a homemade one.
If you decide to invest in a Cheshire sight tube, it can be used with any Newtonian reflector.
