My favorite object.
It was taken on 10/02 from Doughton Park, NC, on the Blue Ridge Parkway. Total exposure is 1h30min, 30 x 3min, Canon 20Da at ISO 1600.
Takahashi epsilon 160, F=530mm, f/3.3. Losmandy G-11, guiding with PHDGuiding and Takahashi FS60 with Phillips ToUCam.
Calibrated, aligned and stacked with ImagePlus, histogram stretched with Photoshop.

Thanks for looking !

Absolutely spectacular. I can try forever and never get close to this.
