IC434 Horsehead and NGC2024 Flame Nebula's

So had hoped for three clear nights as wanted to get to near 20hrs of data but as usual the British weather was not going to play ball but had two nights so better than nothing
. The first night was a full moon and it was bleeding close to the target as usual, but the Antlia Quad Filter did a pretty good job knocking the moonlight back, the second night was better as the moon was further off target, so even better contrast achieved in the data.
So the Image is 247 x 3min subs so 12hrs 21 mins of integration time the data was captured through Sharpcap as usual although this time I had one instance doing the actual capture and a second instance running a live stack from the folder camera which worked a lot better as I just let a script cycle on the one instance taking 4 subs / dither repeat three times then Autofocus then back to the start and repeat over and over. The instance running the live stack also had the ZWO-EAF as hardware to allow me to adjust focus on PHD2 as the Instance running the script was using the Esatto.
After capturing the frames were reprocessed through PixInsight and Affinity phot for finishing off, so the session was 247 x lights at 3 min, 100 flats I used the same flats for both nights, 1 master dark, 1 master Bias.
