NGC 6744 from Wiruna

This represents 95mins worth of 5min shots with the QHY9 from the South Pacific Star Party. It was late (and cold!) on the 2nd night, and I was getting a bit tired and lax with my tracking/balance which has smeared the stars a bit and made it hard to get any more detail in the galaxy. Great object and glad I had a go.

* Scope: Skywatcher 8" Newt with Baader MPCC
* Imaging device: QHY9 with QHY LRGB filters
* Mount: HEQ5Pro
* Guiding: Orion SSAG, 9x50 finderscope, Maxim, 1.3sec exposures
* Exposure details: LRGB 35:20:20:20, -25 degrees
* Stacking method: PixInsight, bias/darks/flats, separate LRGB stacking, deconv on L only
* Summary of post processing: Pixinsight deconv, stretches, curves, colour cal, noise, resized to jpg
* Darkness of imaging site: Excellent
* Date(s) image taken: 1:46 to 4am 15/5/10
