Leo Triplet LHaRGB

[Padraic M]

First real multi-channel integration, using APP and broadband data from three nights of imaging of the Leo Triplet. Getting three nights in a row provided a real learning opportunity, including sorting out some issues with the mount and USB setup. I also upgraded PHD2 and switched to multi-star guiding. RMS averaging at around 0.8".

Total integration is 7 hours, comprising:
56x150s R
56x150s G
48x150s B
4x300s Ha Baader 3.5nm

Combined as LHaRGB in APP and processed with Starnet++, Gimp and Noise Ninja. Luminance channel created by integrating all channels.

SW Esprit 80, ASI1600MM Pro @ -20c.
HEQ5 Pro belt-modded and tuned.
Guiding with AA Starwave 50mm, ASI290mm mini and PHD2.
Imaging sequence controlled by NINA.

Constructive criticism invited.
