Hi
Actually had a night of good seeing / transparency so had the first real outing with the new scope and the second go with narrowband imaging on the Rosette Nebula the details of equipment / Software /settings are below, still need to tweak the flattener in a bit probably by 0.1 - 0.2mm to fully correct to the corners.
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 22 x 180s , OIII 30 x 180S, SII 37 x 180S all at Gain 200 Offset 22 at -20C 1x1 Binned
Assigned as Hubble Palette R = SII G= Ha B= OIII
