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.
