On the Move
As if surrounded by a celestial halo, space shuttle Discovery made its way towards the expansive confines of NASA Kennedy Space Center's Vehicle Assembly Building following a move from its processing hangar on Sept. 9, 2010. A metal sling will be carefully connected to the spacecraft and then operators will hoist it from transfer aisle to the high reaches of the 52-story building before lowering it into place beside the external fuel tank and twin solid rocket boosters. Crews then will connect the spacecraft giving the stack its familiar launch day form. Discovery is targeted to liftoff on the 11-day STS-133 mission on Nov. 1 at 4:40 p.m. EDT.

An updated tutorial by Vince Legge
I am referring throughout to the use of a German Equatorial Mount (GEM).
You will need a magnetic compass, one that you can read down to 1° increments, a device for measuring angles, and a little basic handyman skill but we’ll get to that as we work through the technique
Also you will need to determine the Latitude and

Tuning up a Synta Crayford focuser
Most of the earlier standard 2” Crayford focusers as fitted to Skywatcher/Orion and other Synta made scopes have a particular machining fault. Here’s an easy fix. The example pictured is from a refractor, but the same applies to reflectors. If you have one of these its worth taking a close look at it.

Marking Out and Setting Up Azimuth/Altitude Inscriptions On Dobsonian Type Telescopes
(Also a Quick and Easy Way Of Setting Your Telescope To North)
Hey guys, Nic here. As promised, finally got my act together, and have put this little piece to paper (as it were).
No stuffing around straight into it the process is pretty painless and not time consuming nor does it need a great deal of technical skill, but to help you out I will go through it stage by stage.

VENUS – A Quick non-complex Look!
Named after the Roman Goddess of Love and our nearest planetary neighbour after our own natural satellite the Moon, it orbits at a mean distance of around 108 million kilometres from the Sun.
The ancients saw Venus as a paradise, the home of the Goddess of Love and beauty etc. Some had it as a place of opulence with lush botanical growth and huge expanses of water filled swamp land, while others saw it as a vast desert (dune like) setting with large mountains and valleys.
The folk in highplaces and of different cultures

A Budget Home Observing Platform and Pier
I guess for most of us the ultimate dream is to have that big observatory in the back yard. Unfortunately though, too often it is just that; a dream that likely will never be fulfilled. There are more basic ways to make home observing simple and easy, though, on a surprisingly small budget.
