Hi, Just wondering whether collimation is necessary on a smaller Telescope like mine (https://www.astroshop.eu/telescopes/skywatcher-telescope-n-76-700-astrolux-az-1/p,5010#tab_bar_1_select)? If so, how often do you need to do it, and how do you know when it needs doing? Any other tips on how to do it are welcome.
I have been trying to get my SW 250P (f/4.7) to the best possible collimation as I couldn't manage to focus on any of the planets so far. I just collimated the scope to ready it up for tonight's session. Your feedback is much appreciated!
Hey guys,im currently on a school trip and brought my celestron firstscope with, tonight we ll be trying some dsos and maybe saturn and jupiter,the telescope itself is not collimated and dirty (on the mirrors)So I wanted to ask.in the scope, there is no primary adjustment screws,only the ones to take it off .Does that mean that its set , allowing me to take it off wash it and back on without having to recollimate the primary?
Guys , i am so frustrated .I can't collimate my newt. I m here with my chesire eyepiece trying to adjust the secondary but when i turn the centre screw, the mirror moves a lot and then shifts back to where it was. And turning the little screws arouns it ddnt so much either. I don't have much time before my session (2 hrs) pls help
As a farely new member and astronomer, I've decided to seek help for collimation.
The task seems pretty daunting at first but I think I got the basics down.
Unfortunately I cannot find any answers for the questions I have, so here it is: Is it 'normal' to see the focuser's end?
As you can see in the attached picture (poor quality, let me know if I should do another) we can see a rectangle at the left, the focuser.
I don't think I should be seeing this and I don't know what causes the problem since the secondary 'seems' to be aligned and the doughnut is dead center.
I'm using a XT10 and the focuser is all the way in.
Thanks for your precious time,
