National Geographic CF114 1.25" adapter for DSLR/mirrorless cameras

thingiverse

The National Geographic CF 114mm telescope is a fun budget entry level telescope, but the focuser is quite large. I could not get my camera in prime focus to actually focus on planets and stars. The top of the focuser is just a piece of plastic that is screwed onto the plastic drawtube. I modeled a replacement in TinkerCAD, giving it a smaller profile on the draw tube and actually extending the 1.25" adapter that is part of it. This results in about 15mm more inward travel and a more secure fit for eyepieces. Now I can focus on objects in the night sky and take photos without using a barlow lens. The images are of the Orion Nebula and the Pleiades. Here's a link to the telescope on Amazon: https://www.amazon.com/National-Geographic-Explorer-Reflecting-Telescope/dp/B07L139D2B/ref=as_li_ss_tl?crid=24CUDZV4LQ6OE&dchild=1&keywords=national+geographic+telescope&qid=1610586939&sprefix=national,aps,224&sr=8-3&linkCode=sl1&tag=drcameron-20&linkId=10946fa0d041e9c80bbeead05e051046&language=en_US. It often goes on much better sales.
