The Rosette Nebula, with its inner star cluster NGC2244
A pseudo-HDR image because it's the combination of several developments from the same stacking result (could not bring out the colored nebula and master the stars in a single dev).
Gear: Olympus E-PL6 with Skywatcher 130PDS and CC on Omegon EQ-300 tracking RA
Capture: 10 × 60s × 3200iso, no darks/flats
Processing: Regim 3.4, Fotoxx 12.01+
Site: 50km from Paris, usually Bortle 4-5
This is the SHO result of my first imaging object with the cooled Canon 40D.
Through out the imaging, the camera failed a number of times due to condensation buildup inside and so this is a result of two different 40D bodies and sensors. I captured some HAlpha data with the originally cooled 40D before it failed and the second half of the HAlpha, OIII and SII are captured with the second modded and cooled 40D
Exposures: SII: 30x1200s HII: 30x600s OIII: 30x900s ISO1600
Telescope: BOSMA Beta RE
Focal length: 500mm
Wrapping up in double layer goose feathers I braved the obsy last night. I planned a tour of Auriga with a view to chucking in some favourites. I set up the ED150 on the AZ EQ 6 and fitted the WO quartz diagonal accompanied by my ES 20mm 82'. I stuffed my Astronomik 1.25" UHC (bargain price thanks @FLO) in my pocket too. This set up required the retro children's playroom chair with the legs sawn down due to the position of Auriga. I spent about half an hour checking the plethora of open clusters sprinkled in or near the Milky Way. The sky was one of the best this season so it was a jewelled spectacle and the ED150 reveals such sharp colours enabling me to distinguish the cooler stars in some of the clusters particularly the occasional red giant. As Monoceros reached the meridian I moved to the open cluster associated with the Rosette. Now, for all my efforts over the years, the emission nebulosity has eluded my eyes but tonight with this newish 6" frac I was somewhat taken aback to see a doughnut appear in the view. Switching to a view with the UHC filter was nothing short of astonishing! It wasn't just there; I was falling into its centre. Texture, depth and dark globules were easily discernible. The extent was slightly larger than the FOV with the 20mm so I slewed slowly around and the perimeters and varying consistency of the Ha emission were easily picked out. I spent a long and happy time soaking this up; it was truly outstanding. Thoroughly recommended. I retired happily to the warm kitchen and toast.
Presenting my first attempt at Bi colour imaging. This is the Rosette Nebula (NGC2244), which is located in the constellation of Monoceros.
