M27 (Dumbbell Nebula): The Full APS-C Frame

Here's the full APS-C frame of an image I uploaded some time ago with about a 50% crop. Note that this "casual" image used no flats, darks or bias frames. However, I did use LENR and dithered (manually!) between every subexposure.

_Imager: Pentax K-3II DSLR. _Scope: Meade LXD55 SN6 6-inch f/5 Schmidt-Newtonian OTA on a Vixen GP-DX with SkySensor 2000PC. _Exposure: 8 minutes (30 x 16 seconds) @ ISO 1600. _Guider: Unguided. _Date: Sept 15, 2018. _Location: Near Bayfield, Ontario, Canada. _Sky Conditions: Bortle ~2.5, average transparency.
