What is Reddit's opinion of Celestron Collimation Eyepiece 1.25"?

From 3.5 billion Reddit comments

I also got one of these scopes. Is it possible to purchase better mounts?

Is it still hard to correct the optics with the right equipment? I was thinking about getting a collimator

I'd like to get into astrophotography eventually and a shaky mount will not work for that.

Thanks for the tip. I just bought this Collimation Eyepiece and will give that a try.

Glad to hear there is someone in the same boat as me! I will end up getting an additional eyepiece, but I would think that the one that comes with it would do way more than what I saw!

I'll take another look at the website when I have it here with me and just see what I can tell by just eyeballing it. Perhaps it is off far enough that I will be able to tell just by looking at it. Then I can fix it when the Collimation Eyepiece gets in.

This is the one I ordered.

Good choice?

Ordered! I also ordered a collimator as it did not come with one. https://www.amazon.com/dp/B00009R7RJ/ref=cm_sw_r_cp_apa_glt_fabc_5GACTY7HDPSEPT36CKRY

Is this the correct eyepiece? thank you

EDIT: What kind of scope do you have? I ask because the advice below only applies to Newtonian reflectors; collimation is a different procedure for refractors and Cassegrain telescopes.

While a collimation cap is a very cost-effective tool, I would highly recommend a cheshire collimating eyepiece (AgenaAstro, Amazon) if you can afford one. It works the same way as a collimation cap, but it also has thin wire crosshairs. These allow you to align the optics to a much higher degree of accuracy, or at least make it much easier to do so.

I find that an affordable laser is more trouble than it's worth (you have to collimate them before you can collimate your scope!), and reliable lasers are way too expensive (start at $120). I got a cheshire and it works great; it really is the quintessential collimation tool.

So with refractors, the lens are firmly mounted in place and should never move.

With a reflector, if you did the same thing the mirrors will break, so if you take a bumpy trip out to a dark site you you knock your telescope the wrong way, you need to collimate it.

Most of the time, the secondary mirror never needs to be collimated, but sometimes it does.

There are 2 things you can buy, a Cheshire eyepiece or a laser collimator. I personally prefer the latter due to ease of use, among other things.
