Planetarian

I took out both the primary and secondary mirrors. The primary is in perfect condition. The secondary doesn't seem cracked either although when shining light on it from the side, I can see a very thin half circle half way to the middle of the surface, but this could be a little scratch on the surface only. Otherwise when looking at the mirrored image, can't see any problem. As my laser collimator I ordered, hasn't arrived yet, I tried to do it with a star. I got the concentric circles when defocusing, but one side of the circles were stretched (oval), then I realised that probably the secondary mirror needs to be rotated a little. By the end the stars looked much better, didn't see two of them this time but they were always a little stretched to a certain direction depending on how I moved the secondary mirror. Couldn't test the double image problem on planets as they have gone out of sight by the time I finished messing with the mirror. Anyway I don't have practice yet with alignment using a star so I'm gonna wait for the collimator.

All right, I'm gonna try to remove the mirror later and see from close.

Well, I've inspected the primary mirror and can't see any signs of damage. I'm gonna wait for the laser collimator that I ordered to see if that helps.

No, I was viewing outside.

The cap has one hole in the middle with a smaller cap. I normally remove the entire cap when using it.

Hi, I've got a 76/700 newtonian telescope. The problem is that I see double images. When I try to focus, the two images get closer and closer to each other, and when they are very close, each of them are sharp, but when focusing further, they become one, but the image is blurry. There is a strange thing tho, that when seeing two very close sharp images for example of Saturn, then if I cover half of the front opening of the telescope by my hand, one of the images disappear, and I'm left with the other, sharp image. Same problem with the stars, when they seem sharp, all of them are doubled. I collimated the telescope with a pinhole cap (I'm gonna use a laser collimator soon to double check it). I'm using good quality coated plossl eyepieces with different focus lengths. All of them act the same way, so I'm assuming the problem is with the telescope optics. The primary mirror is not chipped or anything, the secondary seems to be silvered on it's surface so that seems fine too. So can this be an issue still with collimation?
