Horse Head Nebula in Ha

Hello,

These past moon days have been very crisp and clear, so i managed to accumulate 19 hours worth of Ha data on IC434/B33 (The Horse head) nebula.

I pushed my CGEM mount guiding at 0.1 secs/frame using PHD2 for 30mins subs and it seemed to handle the weight of the C11 and the 1700mm f.l. very well.

So here is a quick processing of the Horse Head Nebula in Ha.  Next i will take color images and blend the Ha with the red channel.

Technical details:

Mount: CGEM

OTA: C11@F6.1 1705mm

Camera: QHY12: 38x30min (19hrs), Ha 12nm Filter

Guide: PHD2, with a LodeStar at 0.1 seconds per frame.
