NGC 6188 in Ara: H-alpha test by octane2 NGC 6188 in Ara: H-alpha test by octane2
My second ever CCD image.

On Saturday night I headed out to a mate's property for some dark skies.

I set up a lot quicker this time, and spent my time drift aligning, all good.

The goal was to devote the night in 10-minute sub-exposures to this region, through Hα and OIII to do a HαOIIIHαOIII blend mapped to LRGB.

However, the weather had other ideas. I ended up managing to get just one hour of data, all shot through increasing fog. The halos around some of the brighter stars are a testament to this.

Target: NGC 6188 and NGC 6200 down the bottom
Scope: Takahashi FSQ-106N
Camera: SBIG STL-11000M (operating at -40 degrees; no sweat)
Mount: Losmandy G-11
Exposure: 6x600 seconds, self guided through a 12nm Astronomik hydrogen alpha filter. The only calibration I've done is subtract dark frames. I didn't bother with making flats as I didn't think anything would eventuate from the session.

Captured through CCDSoft and processed entirely in IRIS, with salt and pepper added in Photoshop CS4.

Whew! An amazing picture, and you're so lucky to have stars like this - here in London, we consider ourselves lucky to see a helicopter! :lmao:
