My spider is pretty tight. I’m pretty sure it’s the thick tape I used, the mirror is a bit loose , I was playing around with it before and noticed that the tape is too thick and it makes the secondary wobble. I got the poles to the correct length, so all eyepieces can reach focus, but I’m still having issues with the 10-6mm eyepieces, the higher I go in magnification the more the objects come out like a blob or blur. With the 25mm I can’t seem to get a sharp image, the bright stars are looking like arrow heads or seagulls. Could this be due to my secondary mirror being so scratched up as it was dropped on my driveway and has deep scratches everywhere? Or is it collimation? Or did I not let the mirror cool enough, my primary is 50mm thick, and I only had it outside for about 30 minutes before I looked through the eyepiece. And as I move up in magnifation it gets worse with each increase.

Thanks
Daniel
