One more time that I`m amazed with the performance of my 450D Luís Campos monomod with TEC system. This image of the Rosetta nebula taken on Jen 21,2015 from my home front yard with strong street light and strong polluted skies. For this image I used Baader HA 7nm filter which blocks the light pollution, this image is made with 7 subs/light frames, each frame 15min, total exposure 105min, ISO-1600. No calibration frames added to this imaging session, to eliminate hot and dead pixels I used dithering, darks were not needed since this camera with its cooling system shows very clean images, flats and bias were needed but image shows very minor vignetting since the flattener does very good job on flattening. This is the first session followed by 3 more sessions needed to complete the results of this object, another 2 hours needed to complete HA filter followed by another session on OIII and another for SII. I can always add calibration frames in the followed sessions and combine them with this session since the cooling system is a temperature regulated. I had planes to image couple of more objects for the winter time but it seems it will do with this one only. The final results will come soon.
