A Horse in Ha
A few clear hours last night so with the moon around picked the Horsehead Nebula (IC 434) / Flame Nebula (NGC 2024) and surrounds for some H-alpha imaging.
ASI294MM Pro @ 0°C
102mm ED F7 + 0.8x flattener/reducer (F5.5 @ 560mm)
7mn Ha filter
AZ-EQ5 Pro
Orion 50mm Mini guide scope, ASI120MM-S guide camera
36 x 300 sec lights - 3 hours total.
32 x darks
30 x flats & dark flats
Captured using APT with PHD2 for guiding. Stacked with ASTAP & stretched in Photoshop.
Maybe one day I'll get the right weather to get the RGB data to go with it, but the way it's been I will probably have time to save up for my other NB filters before then...
Cheers,
Mark
