Rosette Nebula
Target: Rosette Nebula Caldwell 49 in the constellation of Monocerous
Distance:5200 Light years
Object Type:Large spherical HII region 130 light years diameter
Date:25th and 26th March 2020
Location:St Helens, Merseyside. Bortle 8 sky at new moon.
Exposure:19x 240s Ha; 20x 240s OIII; 24x 240s SII, 30x 240s Darks with gain 2000 offset 20 temp 7-10 deg C.
Flats:30x 1.25s Ha flats, dark flats. 30x 1.0s OIII flats, dark flats. 30x 1.5s SII flats, dark flats. 15 deg C.
Integration:252 min.
Imaging:Altair Astro 60EDF, 1x Flattener, Zwo EFW mini filterwheel,Bader Ha, OIII, SII, Altair Hypercam 183M Pro.
Guiding:Altair MG32 mini guidescope, Zwo ASI120MC camera.
Mount:Skywatcher Star Adventurer Pro.
Software: APT,PHD2,Sharpcap Pro (polar alignment),Deepsky Stacker, Photoshop.
Unusually clear skies for two consecutive nights, free of aircraft con trails amidst the Covid 19 lockdown. This was my second attempt at getting enough data on this target to process in Hubble palette. On the previous attempt the clouds rolled in before I captured any SII data. As the season for this target was drawing to a close I was very pleased to get the opportunity to image it again.
