Hi
We had three clear nights in a row last week so as it was work day decided to do one filter per evening, the image below is the result and the specifics are also listed. Bit disappointed that the running man never came out clearer but that could be conditions, the integration time is made up of 80% of the exposures filtered on quality measurements.

Scope : APM-LZOS 130/780 F6
Mount : Skywatcher EQ6-R
Flattener/reducer : Massimo Riccardi 0.75x for LZOS so scope at F4.5 for this image.
Camera: ASI 1600MM PRO + ZWO 8 Position Filter Wheel
Filters : Ha / OIII / SII Baader 7nm
Guiding : Altair 60mm Scope + GPCAM 290M
Control : Eagle 2 Pro + Sesto Senso + Ecco for Dew Control
Software SharpCap Pro : for Image Capture, Live Stack Preview and Polar Alignment / PHD for guiding / EQMOD via EQDirect Cable / Stellarium
Processing via Astro Pixel Processor and Photoshop CS

Exposures : Ha 36 x 180s + 76 x 45s, OIII 60x 120S, SII 52 x 120S all at Gain 75 Offset 30 at -20C 1x1 Binned
Total integration 389 minutes

Hi Brian,
No it's not Hubble it is Ha Red, Oiii Blue and Sii Green with a bit of blue and green added in APP basically to achieve an image that I was visually happy with rather than anything scientific :D as we want to do a print of it for the wall.

Cheers
Nick
