So I followed you guy’s suggestions and it worked! The mirror is completely out of the focalizer! Can’t wait to use it tonight finally! Thank you so much to everyone that helped!

Thanks guys! I’m gonna try to move the focus tube out of the way of the secondary mirror. Slightly angry that this wasn’t exactly what I bought online, but if it doesn’t make me an expert on telescopes, nothing will lol

Thanks! I took some more photos of the telescope through the top, as well as some other angles: https://imgur.com/a/Sstk3kP this honestly feels like I got a little bit scammed. The website I bought it from did not mention anywhere that the telescope was homemade.

Well, it seems like my only option is to try to move the focus tube up. Thankfully, since everything is homemade, I think it shouldn’t be very hard to “customize” it. By the way, is there an answer button anywhere in this forum? I can’t seem to find another way to reply other than adding another comment

I think I might have used the wrong term in English. The way that this particular telescope is built (I later found out it was a self build by the person I bought from) has the secondary mirror touch a tube that leads directly to the eyepiece. I’m pretty sure the mirror tilted enough to go inside this tube. In Portuguese we would call it a “focalizador”. I’m not entirely sure in English, though. But it doesn’t seem like it’s supposed to move edit: looking at the other answers, yeah my telescope looks nothing like that lol. It’s a lot narrower, so there’s no space between the mirror and this tube that I described

No, it’s completely fixed. Unrelated, but thank you for adding a Portuguese translation, that’s very sweet hahah

hi there! It’s my first time ever posting here. A little while ago I started to look for my first telescope, and after a lot of research, I decided a dobsonian was the best recommendation for complete noobs. Unfortunately for me, name brand telescopes are very expensive in my country, so I ended buying a used dobsonian, with optics made by well known Brazilian ATM (Sebastião Santiago Filho). However when I received this telescope I noticed half of the view through the eyepiece was completely black, possibly obstructed. After investigating, I believe the secondary mirror found its way inside the focalizer, and the “obstruction” is the reflection of the inside of the focalizer tube. I’ve been in contact with the person that sold it to me, but he doesn’t seem to know how to solve the problem. Please excuse if the terms I used aren’t very clear, I’m freely translating from Portuguese. Here’s some pictures I took of the inside of the telescope: https://imgur.com/a/o545Cmm Does anyone have any idea how to fix this problem? I’ve tried messing with the angle of the secondary mirror, but it doesn’t seem to do much.
