Vasya,
you can't remove lenses from optical system just like that - they are there for a reason.
This is why the stars look triangular.. very bad case of coma, those lenses you removed were there to correct this problem.

BTW, which telescope is that?

EDIT:
OK, I see.. it is LZOS 60mm.
Those lenses yopu removed are at the back end (eyepiece)?
So you took this photo in prime focus? Should be better - I used to have that scope long time ago and the objective optics was pretty good.
How about focus and alignment of the whole system?
