Hi
I started this object at the beginning of the month and managed to get the Ha and OIII data but as usual the clouds and rain came in so I have had to wait until last night when the weather forecast was cloud all night but the sky looked promising when I took Hunter and Gunner out for their last walk of the evening so I got everything set up and managed to get 3 hours of SII data. It was taken with
Takahashi FSQ106ED at f5
Starlight Xpress SXVF H36
5nm Ha, OIII and SII filters
Paramount ME
Auto guided by Starlight Xpress Lodestar and OAG using dithering
Exposures were 12x20 minutes each for Ha and OIII and 9x20 minutes for SII mapped to the HST palette so SII:Ha:OIII = R:G:B
All sub frames were fully calibrated with darks, dark subtracted flats and bias frames
The Ha and (Ha+OIII) versions can be seen on the 'Nebulae 2' page of the image gallery on my website

Thanks for looking
Best wishes
