Horsehead Nebula (IC 434) in Bicolour

[AnakChan]

Despite having a new camera this year, I've hardly produced any images as most of the year has been on learning how to use the new toys. I thought I better produce one more image before the year end, and with the Horsehead Nebula in Bicolour. So here's my version of of it with Hα & Oiii taken in mid Dec. I wanted to capture in landscape to get the wall as much as possible but the flare from Alnitak is a bummer. I should probably should have framed it better.

Image capture details are as follows :-

• Takahashi µ250CRS @ native 2500mm F10
• Vixen AXD Mount
• ASI6200MM/EFW/ZWO filters
• -10C 100 Gain 50 Offset
• ASI174mm mini guide cam on ZWO OAG M68
• 63x 5 min Hα over 2 nights
• 48x 5 min Oiii over 2 night
• (Total 9.25hrs)
• 30x flats of each filter
• 30x flat dark matching for each filter flat
• 50x darks
• Acquisition managed by N.I.N.A.
