The Eagle Nebula

This is an image of M16, the Eagle Nebula in Serpens. Taken through the WO GT-102, it was put together using 10 x 5min RGB images shot on an Atik 460ex SOC camera, and 12 x 10min through a hydrogen-alpha filter on an Atik One.

The problem with imaging from this latitude at this time of year is that it never really gets dark. However, narrowband imaging can still work well, especially with the murky light-polluted southern horizon I have.

This shot of the Eagle Nebula, M16, in Serpens Cauda. was taken with an Atik 314L+ through a 7nm Baader H-alpha filter on my SkyWatcher MN190. It’s a stack of 16 x 5 min exposures, processed in ImagesPlus 5.

One of the best things about observing in the summer is that it never really gets cold outside at night. One of the worst things is that it never really gets dark… However it’s the only time we get chance to see some of the treasures of the southern ecliptic. This is an image of M16, the Eagle Nebula, situated in the constellation of Serpens, close to its borders with Scutum and Sagittarius. Taken through the MN190, it’s composed of 6 x 5min exposures through Hα (mapped to red),  SII (green) and OIII (blue) filters. Although I took care to focus before I started, the stars are a bit bloated, I suspect because  its altitude was just 20° above the horizon.

Having had some success with M17, I thought I’d try and have a go at M16, which is just to the north of M17. They’re both in quite a difficult region of the sky for me in some respects – both low down, and once they’ve passed the meridian the wall of the observatory starts to get in the way! So this image is a composite of just 9 x 5min exposures through the hydrogen alpha filter, prcessed as ever with ImagesPlus. I’m really quite pleased with it, given the small amount of effort that went into it; plenty of detail, and the Hubble-famous Pillars of Creation are clearly visible in the centre.

And is it just me – or does this look a lot like the Orion Nebula?!!
