Flaming horse

[jacko61]

here's Monday night's efforts on the horsehead and flame nebulae. First decent night here since mid november so despite having a permanent set up I took quite a while to polar align and calibrate my guiding in PHD2.  The first sub I took was awful - hazy and distorted. After some investigation and stripping down I found condensation BETWEEN the two lenses in the Flat 73A which took some effort to clear (held it near the shed heater and then wrapped a dew strap around it).  As a result I only managed 2 and a 1/2 hours of 3 minute subs but I'm reasonably happy. 

WO ZS73 plus Flattener,  ZWO ASI2600MC pro,  Skywatcher EQ8r pro.  50 x 180 second subs captured and processed in APT, PHD2, DSS, STARTOOLS, STARNET and GIMP.
