I believe I will go with this one indeed.

With all the support from Lady Fraktor and some other useful contribution I understood I need an alignment / collimation eyepiece. Is that still true for this telescope above? Would this one be ok?

It comes with a plossl 25mm, should I include a 17mm as well?

As you may realize I want to take advantage of the black weekend, so if there is anything that makes sense on this link pls help me to identify.

Good for you!
Great choice, I'm sure you will have a lot of fun with that telescope! Also keep in mind that it is not a "beginner's scope" but a quite serious scope in the sense that it will keep you entertained for many years to come.

Have fun!
Clear skies!
Steve

You will still need a collimation cap to make sure the secondary is square under the focuser tube, a laser (which I will still say is not the best when beginning) will not do this for you.
Enjoy the telescope and ask any questions that arise :)

Is the laser useless without the cap? ;(

I just asked them via email to add to the order, let see...

Isn’t it strange that they see so many telescopes and gear, but only have one collimation cap from a single brand (TS optics)?

Not entirely, no. But you need the cap to make sure the secondary mirror is well positioned.

Not really. They're an easy "do it yourself" project.

Yes and no, if your secondary is positioned properly the laser is quick and accurate.
If your secondary is not aligned, just using a laser is a big pain where you sit.

The collimation cap/ Cheshire will have you aligned in minutes without the laser.

As added information, the chances of your laser arriving in collimation (pointing out straight from the holder) are quite slim so you may want to do a search on how to collimate a laser collimator :)
