Arrived in three days and I ordered late afternoon.

sourceSelector:'' This is necessary to compensate for the variation in mass and balance when using different eyepieces; the altitude bearings are of sufficiently low friction that without the removeable counterweights a heavy eyepiece will tend to tip the scope down, while a small eyepiece will allow it to rise. defaultImage: '', }, { Capture breathtaking photos with our affordable astrophotography cameras. }, { width: 200, Rotational adjustment is facilitated by a small flat machined into the end of the threaded rod, which allows it to be gripped securely with a small wrench; loosening the top nut slightly allows it to be rotated and held in the desired position while the nut is re-tightened. When used in conjunction with the azimuth ring, this allows the scope to be accurately aimed in alt-az coordinates. defaultImage: '', Below are a few common features and things to think about before making your decision and final purchase. Not sure how to choose a telescope? Cassegrain telescopes, such as Maksutov-Cassegrains, "fold" incoming light using two mirrors and a front "corrector" lens. Did you make this project? entityId: 15189,

These scopes will appeal to the more technically inclined. The four rectangular vanes are welded to a central segment of tubing, into which an aluminum reducer bushing is press-fit. Referring to the manual is highly recommended.

As we mentioned before, these things are big; think about what you’ll be using it for. This ring was cut from the same FRP panel as the bearings, and includes angular markings in single-degree increments. My shortest eyepiece is 5mm, but this level of magnification (250x) requires very still air and very good atmospheric transparency; on most nights I end up not going past the 9mm. entityId: 99799, The secondary spider is thin enough to minimise defraction spikes, but substantial enough to support the secondard mirror assembly well.
