M16, M17, M20 and reprocess M8

Post by weixing »

Hi,
Saturday night was quite good... although had a layer of high cloud, but no large cloud flying in 90% of the time when I'm imaging. I start slightly earlier and manage to took 3 objects that night. :mryellow:

All the images of the 3 objects (M16, M17 and M20) use the same settings:
Lens: Canon EF 400mm F5.6L + 1.4x (@F8.0)
Camera: Canon 450D Mod + Astronomik CLS EOS Clip-Filter
Mount: Vixen GPD with Single Axis Motor Drive
Location: Tampines, Singapore
Images: 60 images x 1 minute exposure @ ISO1600
Orientation: Right - West, Left - East, Up - North and Down is South.

All images are crop to 8R (3023x2421) and resize to 720x577, so all have same field size (~1.6 x ~1.28 degree)... can see the relative size of which objects. I also reprocess the M8 Lagoon Nebula and crop to the same as the rest.

Below are the images:

M16 Eagle Nebula

M17 Swan Nebula

M20 Trifid Nebula

Have a nice day.

Beautiful! Shooting them in Singapore makes it even more challenging and thus more rewarding!

Very nice! These are the kind of images that I show my non astro friends and they are amazed that this can be imaged and seen from our challenging Singapore skies.
