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.

We haven't had much in the wy of winter yet, though I'm told there's a cold front on its way. After the summer we had, I was hoping for positively arctic weather, but alas, global warming seems to have kicked in now.

He looks slightly older than his early thirties; I must assume he has managed to avoid the wrath of established interests thus far.

Sitting through the cold the last few nights. M16, M17 and the Cat's Paw nebulas. The last one did not come out well and need more data I think. Actually, all of them will do well with more. I will work on that tonight if the wind is not too strong.

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.

Two very bad pictures of M27 or the Dumbbell nebula. Last night, 39 photos of 120 seconds stacked in an App called Nebulosity. A few tweaks in Photoshop to no avail. Take me out the back now before I do more damage.

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.

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. WTF!!

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.

Nothing short of astounding really... that we can "directly" observe such immensity.
