As most of us in the Four Points area and beyond have experienced in recent months, traffic heading west-bound on RM got worse after re-striping took place on May 9, The change shortened the right turn lane for traffic headed north on RM and changed the use of lanes causing driver confusion. The change was intended to allow safe turns into the center lane from area businesses which previously had to contend with the traffic racing toward the RM intersection. They are doing this soon to avoid overlap with school starting in mid-August. Note: TXDOT is also working to complete re-texturing of RM with a safer texture coat before school starts for the fall this was originally planned for May but was delayed due to technical issues with the texture mix.

Telescope Making Links - Supplies and Components
A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularized by John Dobson in and credited with vastly increasing the size of telescopes available to amateur astronomers. Dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large, portable, low-cost telescope. The design is optimized for observing faint, deep-sky objects such as nebulae and galaxies. This type of observation requires a large objective diameter i.
There are many good Instructables here about making your own backyard Dobsonian telescope. Many of us start in the 8-inch to inch range, and spend many long nights cruising around the Cosmos checking out the sights. Eventually, however, many of us are afflicted with a longing called " aperture fever " -- the desire to have a much larger telescope, that can gather just a few more bits of light from the Cosmos. Ever since I started out in amateur astronomy, I have named my telescopes. I always knew I was going to build a large telescope, and had waffled around with names.
