Hi,
This was on Monday night from the Blue Ridge Parkway (NC). Celestron C9.25 working at 1480mm focal length with reducer, f/6.3. Canon 20Da at ISO 1600. 29 frames 3 minutes each for a total of 1h27. Autoguiding with Tak FS60, Phillips webcam and PHDGuiding software, Losmandy G-11 mount.
ImagePlus, Photoshop and PixInsight for image processing. The picture has been cropped 1/4 of the original size.
It's amazing what automatic guiding can do compared to manual guiding.
Thansk for looking !
