NGC7822 in HA

[RichLD]

Captured on 21/09/2017 - I've been fiddling around with the widefield dual rig and currently have it set up as a double HA device - after calibration I resized the QHY9m files to match the QHY163m subs in good old Registar.

QHY163m - 20 x 600s (bias, darks, flats)

QHY9m - 15 x 900s (bias, darks, flats)

2 x Nikkor ED180 camera lenses at f/3.6 (using aperture masks to avoid diffraction spikes)

HEQ5 (guided)

Baader 7nm HA filters

Captured using SGP

QHY9m subs resized with Registar

Registered and stacked using PI (Linear Fit)
