Description

Three hours total integration: 36 x 300 sec lights at 240 gain; 13 darks; 15 bias; 15 flats.

Captured in N.I.N.A. under Bortle 4 skies at Turner Mountain Nov 16-17, 2020

Calibrated, stacked, cropped in Nebulosity, Photometric Color Calibration and stretching applied in Siril.

William Optics FLT98 618mm f/6.3 with TeleVue 2X PowerMate

ZWO ASI071MC camera

OAG guiding

It became obvious in the processing that the total time on this fabulous large target - the Bubble Nebula - is way short of what's needed. My effective f/ ratio with the PowerMate is 12.6, and with a 4 inch telescope, I'll need 20 or more hours when I try this again. Next fall?
