Last summer I took the Criterion 6000 out and looked at Saturn and found some flaring and I couldn’t get Jupiter or Mars to resolve (I think I was looking at Mars) so I thought it needed collimation. Last night I took the tele out, polar aligned, tested the drive motor and all seemed good. I then set Aldebaran on tracking, defocused on lowest power and noticed the secondary shadow was slightly off center. I thought I’d try my first ever attempt at collimating and just made things worse . . . way worse.
Things that happened . . .
1) I tried following the manual by putting the star on the edge of the FOV in the direction of the shadow and adjusting the screw opposite that direction by fractions of a turn. Unfortunately, the way the shadow was and the way the screws/housing were oriented there was no exact opposite screw so I started adjusting the one nearest.
2) Upon adjusting the secondary screws the secondary housing slipped under the torque and rotated clockwise. I twisted a little more until it tightened to a stop.
3) Things got worse. The defocused star moved around the FOV so I tried compensating, but then the circle halo became oblong/elliptical shaped. I tried getting the egg back to a circle and the shadow centered but then the halo went from egg-shaped to like a delta (or semicircle) shape.
4) I got it back into an eggish shape with the shadow a little off center, but then clouds rolled in.
5) I fought through the clouds and the sky cleared up but my further attempts proved futile and the halo is now kind of like a gumdrop shape with the shadow a little off center to the top.
I am wondering if when the housing slipped it cause the halo to take on different forms.
I fear that by adjusting the screws so much I have damaged the corrector lens
I fear I have placed the things so out of alignment it will take a telescope repair person to fix it (which I have yet to find in my area).
I have literally working myself into nausea thinking about how bad I messed up and if it can’t be fixed.
In hindsight I feel like the telescope was never out of collimation but my wanting everything to be perfect and perfectly centered has caused significant harm
Can someone please tell me that everything is going to be okay and help me get my telescope healthy again?
What the FOV roughly looks like (see attached - hope the attachment works)
