Great stuff! Now is the perfect time of year for sky viewing - pity you can't do it without freezing solid though. :-)

Long Johns, tracksuit pants and a pair of jeans. Long sleeve vest, T-shirt, 3 jackets. Wool lined hat with ear flaps and one of the jackets got a hoody that goes over the hat. Gloves and 2 pairs of socks in hiking boots. You sit out there for 4 to 5 hours, so it still gets cold.  |

But it is warming up a bit lately. At least around these joburg parts.

After the summer we had, I was hoping for positively arctic weather, but alas, global warming seems to have kicked in now. Tweefo is astronomy geek Jesus: He froze for our grins.
He looks slightly older than his early thirties; I must assume he has managed to avoid the wrath of established interests thus far. |

The Eagle nebula is a bit clearer. I took more photos at a higher ISO and added them to the other day's pics.  |

My best Trifid nebula so far. 50 Exposures of 120 seconds each at ISO 800. The object is now high in the early evening. All my previous attempts were through a thicker part of the atmosphere.  |

This image of M42 took me from 12:30 to 3 am on Wednesday night to do the imaging. I took 50 pics but only used 17 in the end, so this is about 38 minutes worth of data.  |

The Tarantula nebula. This is almost 3 hours of data taken over two nights from my backyard. According to the Bortle light-pollution scale, Middelburg rates at 5-6. It came out rather colourless. When I took pictures from a dark site in the Freestate, I got lovely green tones, and that was with only 40 minutes of data. Looks like I need another 3 hours to add to this.  |

NGC 253 or the Sculptor galaxy. Also called the Silver Dollar galaxy. Far too much noise. This astrophotography comes with a very steep learning curve.   Nothing short of astounding really... that we can "directly" observe such immensity. |
