Description

SH2-129 or "Flying bat nebula" , a pretty big nebula in Cepheus, close to Alderamin.
In future, I hope to gather some OIII data to reveal the Ou4 "Squid nebula", a recently (2011) discovered PN.
------------------------------------
Utilizing every cloudless night, even a moon polluted one...
My first attempt to gather some photons at full Moon. It seems to work.
Moon was in the south, the target in the north.
A 2% difference in the illuminated part of the Moon seems to have a huge influence on SNR.

It is also the first light for the iOptron SmartEQ Pro mount. The guiding works pretty well. I tested it
up to 30min.

----------------------------

Rev. B : additional 5h of Ha, drizzle & de-conv
Tried to aquire some OIII but the signal is VERY weak. For OU4 one need to bring the big guns :-)
