The Rigel Aline Collimation cap offers a convenient and affordable means of collimating a Newtonian telescope.
If you simply look down the focuser drawtube it is hard to tell where to place your eye. If you look Into Your telescope through an Aline and you will see a bright white circle surrounding your eye's pupil, making it easier to center the primary and secondary mirrors.
Fits firmly into the focuser and features a convenient highly reflective inner surface.

It may just be me but as a spectacle wearer I can find it awkward to keep my eye correctly positioned and the edge of the primary in the field of view when using a Cheshire (it usually ends up as one or the other). Because the Aline cap lets me get my eye closer to the focus tube I find it makes it much easier to see that the primary is correctly centred. I still use the Cheshire, as I find the crosswires help with the fine tweeks, but the Aline cap is so quick and simple to use as a check of the basics before and after using the Cheshire.

It's a collimation Cap, so not a lot more I can say other than it worked as expected and the item arrived quickly with the usual great service from FLO.

Firstly, FLO service, perfect ad normal.
This Aline works well and does exactly what it claims. Easy to use, but still comes with instructions.

Been using a DIY collimation cap since I got my 200P and never been too happy that my collimation was any good. This turned up yesterday and it made the task so much simplere, the silver inside surface makes positioning the primary mirror centre spot very easy.
