Hello stargazers, I am using a Newtonian telescope (114mm/900mm) that has a 0.965" (24.5mm) focuser. My eyepieces are all 1.25" (31.8mm), so I use an adapter to make them fit. Yet, because the adapter adds distance between the eyepiece and the primary objective, does using an eyepiece adapter affect the way that my focuser works? Thank you for your advice.

Great, thank you both, @vlaiv and @Franklin, I put the o-ring in place and the finder scope sits much more snugly now! And that's good to know about the extra papers, I actually realized now that I took the extra little circular papers out to the bin this morning with the rest of the packaging, and I'm glad to know I haven't made a catastrophic mistake. 😅

Hello stargazers, I recently was given a 114mm/900mm Newtonian, and I am very satisfied with it. I just have two quick questions about its assembly: 1) I attached my finder scope using the two bolts on my main telescope's tube, but the mount for the finder scope came with a small rubber band around it, shown in the picture below. Does anyone know what this little rubber band is for? 2) My Newtonian has a small circular piece of black paper behind its primary mirror, shown in the center of the picture below. The telescope also came with a whole stack of papers the same size that were just loose in the box. What are these small circular papers for? Should I leave the one behind the primary mirror that is currently there? Is there any reason to keep the other pieces of paper that are the same size? Thanks for the help!

Thanks Elp, I appreciate your advice! Do you think the threaded steel bar needs to be the same diameter as the holes in my counterweights? These are my two weights, and both have a 25mm hole, and a screw on the side to tighten them to the rod, but I'm concerned that if the rod is thinner than 25mm, they won't be stable.

Hello, thank you in advance for your assistance! I recently received a Konus Super Polar System equatorial mount as a gift, which I will use with my 114mm/900mm reflector scope. The mount is in great shape, but it is missing the counterweight shaft, nut, and flange. I would really appreciate your advice on replacing these! You can see a lot of pictures of the exact type of mount I have here. I believe that this mount is similar to an EQ3.2, or the same as a Celestron CG4 or CG5. The hole in the mount where the counterweight shaft screws into is 15mm across, and the interior holes in the two counterweights that came with the mount are 25mm across. Here is a picture of my mount: Here is a picture of the manual, showing the pieces I am missing: And here are a few pictures from the internet of the same mount, but showing what I am missing: the counterweight shaft, "toe-saver" nut, and the flange (the reverse cone shaped connector): I have found a 25mm diameter counterweight shaft that I could order online, at this link. But, will this be able to screw into the 15mm hole in my mount? Additionally, the flange on this looks entirely different, but to be honest I am not sure how necessary the flange really is. I would appreciate your input on if I should even worry about finding a similar flange. I did find a replacement counterweight shaft that I could order that has a similar looking flange, but this is only 20mm in diameter, linked here, but I assume that would not work with my counterweights that have a 25mm hole. Please be aware that I am located in Italy, so I am intending to order from a European site to make shipping easier. I have also seen some people with the same mount who have done a DIY counterweight shaft, and this is why I am posting on this forum. If the options above won't work, how would you recommend that I make a new shaft and flange myself? In this image, I see someone using two large nuts where the flange goes, but does this give the necessary stability? TLDR: What do you recommend I do for a mount with a 15mm hole for the counterweight shaft, and two weights that have 25mm holes in them?
