What's going on here? ISRO: Pital Crater - Picture from Mars Color Camera (MCC) 23-04-2015 http://buff.ly/1IOF9YN http://buff.ly/1IOF9YO
Pital crater is an impact crater located in Ophir Planum region of Mars, which is located in the eastern part of Valles Marineris region. This  image is taken by Mars Color Camera (MCC) on 23-04-2015 at a spatial resolution of  ~42 m from an altitude of 808 km. Wall of the crater and chain of small impact craters are clearly seen in this image. This crater is having the diameter of ~40 km.

One thing about astrophotography: there's always more to learn. There's always room for improvement.

So tonight was gonna be the night I first saw and imaged C/2015 G2. Because I forgot I live in a valley. Try again when it's further east.

Practice makes a little bit less imperfect!
Centaurus A - NGC 5128 http://buff.ly/1e4ZOLp
Image captured over two nights, total integrated exposure time of 26 minutes Captured through Celestion C8 with f/6.3 focal reducer Canon EOS 1100d, driven in tethered mode by APT 158 x 10sec, ISO800 light frames Processed in Iris: pre-processing with bias, dark and flat field images, stacked using COMPOSIT2 algorithm, colour balanced, levels set in logarithm mode. Big improvement over my first attempt at capturing this famous galaxy!

Working on my best-yet CenA image. Captured 360+ frames so far (over two nights), of which I've discarded about 200 (mostly tracking errors, bad atmospheric distortions). The second evening's seeing was worse, the sky was more transparent so that that batch of images are brighter and blurrier. Interestingly, my stacks so far have still made the result better than just using the first evening's sharper frames. Starting to look as if the solution to all life's problems really is "Integrate more data. More data! MORE!"

RT SmithsonianAirSpace: TDIH 1973: #Skylab, 1st U.S. space station, was launched. Skylab Orbital Workshop on display: http://buff.ly/1EKHtbT http://buff.ly/1EKHr3H
The orbital workshop is the largest component of Skylab, America's first space station. It houses the living quarters, work and storage areas, research equipment, and most of the supplies needed to support a succession of three-man crews. Two complete Skylab space stations were manufactured and equipped for flight, and one was launched into Earth orbit in May 1973. After the Skylab program was canceled as effort shifted to Space Shuttle developme...

Introduction
This is the g+ page for Urban Astronomer, a South African based website which tries to help those of us interested in the stars to learn a little about astronomy. How to observe?  What are those things you showed me in your telescope?  What are professional astronomers learning about the universe while I enjoy the view?
