WebThe Bird-Jones design allows having a physically small telescope with a long focal length. The Celestron PowerSeeker 127EQ has a focal length of 1000mm even when it is much smaller. It is using a permanently mounted Barlow lens in the focuser to increase the focal length which is degrading the quality of the image. WebThe 114 is a flawed bird-jones telescope with bad optics. Avoid! The 130 is better but still pretty small for that price. I would avoid both. The mount's not even ideal. For $399 you can get a much more capable telescope with a larger aperture, e.g. a 6" or even 8" dobsonian ( Links on what to expect in different telescope aperture sizes ).
