... NGC 281 (Sharpless 184) is a bustling cradle of star formation about 10,000 light years away. ... The central stars are being formed from the surrounding gas, which emits a large amount of hydrogen alpha (Ha) light after being excited by stellar radiation. ... The dark areas overlaying the brighter ones in the middle of the image are dense clouds of gas known as Bok Globules. ... 4) Image registration . ...

... The source exhibits a mas-scale structure which, according to the USNO multi-epoch monitoring at 2.3 and 8.4 GHz over the period from 1994 July through 1998 April, undergoes considerable changes in the brightness distribution and positions of the major structural features. Our image is qualitatively consistent with the structural pattern of the source. ... We note a difference of ~90 in position angles of secondary components in our image and the 5 GHz VLBI image by Shen et al. 1998). ...

Here are two images of SN 1998ey in NGC 7080. The discovery image (Dec.5th) was stretched quite a lot and only just visible above the noise. It was a 30 sec. exposure with a 30cm f/6.3 SCT and Starlight Xpress ccd in bright Moonlight and mist. I was very lucky to have detected it under these conditons as it was at mag. 17.0 or a little fainter. ... Back to 1998ey .

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
