M7 M8 M20 Mosaic Final? Version

[avandonk]

This mosaic is made up of eight panels. Taken with the 300mm lens. The FoV is 15.3 X 7.9 degrees.

Each panel has 20x(15s, 30s, 60s & 120s) exposures at 1600 ISO at f/3.5. The usual HDR method. This is a total of 640 exposures for a total of ten hours. This is 48GB of tiff data. The 'new' computer an i7 920 with 12 GB of ram and sixty four bit operating system made the huge job of processing a lot faster and less tedious.

The original tif is about 750MB. Even though the data was collected over many nights, the fact that it had rained before the skies cleared each time meant transparency was very good. Collecting all data near the zenith also made gradients far less of a problem than usual. GradientXterminator was not used.

A magnificent image Bert. Well done. Sensational.

Those original file sizes are Skymapper like :eyepop:
Ditto what Greg said...and I have already said previously :thumbsup:

Great Bert!

The folds of dust across the scene remind me of a large scale fox fur nebula for some reason. Nice transitional glow toward the center of the galaxy too. More mosaics please! They can't be beaten with it comes to resolution coupled to a wide field vista. Thanks for sharing.

Bert - imagine all you could get from a darker site!!!? breathtaking

[multiweb]

That's awesome! Resolution and colours are excellent. One of your best. :thumbsup:

Beautiful mosaic Bert! Would look awesome on the wall!

The Universe is Fractal Jase. When dust and gas that is gravitationally bound no matter how weakly, is disturbed by stellar winds and supernovae and distorted by magnetic fields then it is not surprising that the same sorts of patterns emerge. The supernovae just add more material to this cosmic river. It is a bit like water flowing over rocks. We humans have evolved to recognise patterns as a means to survival. It has given us art music literature science etc. and all the other higher things that define who we are.

Simply a lovely vista, strangely in a previous thread, you didn't think your work was of malin competition quality ...... I disagree, and would like to see this in next years images, although perhaps the detail would be lost in their file size request.... If mosaics continue, that will need to change.

I agree with you Clive re Malin Quality (he usually awards a Milky Way expanse image too if it's good) but I still think it would look good even at a restricted size, one of the benifits of mozaics :thumbsup:

On ya Bert Malin :D

Bert....a lovely image, probably the best I have seen from you talented Sir.

Wonderful image Bert, the highlight for me being the dark nebulosity highlighted by the lack of stars.
