Like A Sketch... by ZeSly
Like A Sketch...
This one will probably not be very popular, and yet ... I made this picture without conviction penultimate morning at Pehoe Lake while, as every morning, mountains timidly came out of the mist. It should be one of those pictures we made just to see, saying it would give anything good and we will forget it very quickly.

But when I saw it on my hard drive on the Sunday following the stay, at home, I loved it. It took me three days to find in which part of the Cuernos it was located. I have no picture at wide angle to locate it. This peak is always in the clouds.

There a strange perfection in this image. It is very noisy but perfectly clear. The result of abstract adjustments following night shots attempts yesterday: ISO 2000 and 1 / 4000s. But the noise is beautiful, kind of grain. Looks like a drawing made with a soft pencil or fusin on rough paper.

Now I think this s one of the best photo I could do in Patagonia, if not THE best.

M42 - The Great Orion Nebula by ZeSly
M42 - The Great Orion Nebula
The Orion Nebula is the most famous nebula in the sky. It is the Great Princess of Winter Nights. It is easily visible unaided eyes just below, or above if you're in southern hemisphere, the Orion's Belt and can be recognized with a simple binocular. In fact the Orion constellation in its entirety is a large nebula which M42 is just the most luminous part. It is also a star nursery : observation with the Hubble Space Telescope reveal protoplanetary disks inside. It is located at a distance of 1,350 light-years and is estimated to be 24 light years across.

Unlike a novice might think, this is not an easy photographic target. Especially when you want to show everything. That is to say, the trapeze at the very very bright center and all the dust and vaguely ionized gas that surrounds it.

First difficulty: it happens in winters. And recent winters have been mostly rainy. Thank you global warming. Before, we had beautiful sunny days and negative temperature guaranteeing us clear nights. It's been 4 years that I expected to be able to point the FSQ to it. And it does not happen as expected.

To acquire all the extreme dynamics of this part of the sky you have to mix different exposure times. I had done some testing in October and I was surprised to see the trapeze completely burned on 30s exposures. We must come down to 10s and again, it's limit. For the weaker parts, I made 5min exposures, 10min would not be luxury.

Last difficulty: it is low on the horizon that does not leave much time along the night to acquire all the necessary exposures before it is in the turbulence and light pollution. Especially as the sky was diffusing light that night with 20.7 SQM. I've seen better.

I had the idea to make two night from 21 to 23 December last year, but the telescope has been covered by dew the first night and I foolishly forget to turn the heaters on. The second night was much more dry, curiously.

I finally acquired 34 exposures of 5 minutes and 14 
exposures 10 seconds. I wished I have more. It should have been doing 5s, 30s and perhaps poses 10 minutes exposures and then a second night would not have been too much.

For the processing, I can appreciate the power of PixInsight even it is not easy to tame. Several day of "work", I had to made it twice.

34 exposures of 5 minutes and 14 exposure of 10 seconds for the bright heard.
