The silver heat reflecting paint that now adorns the observatory roof and south facing wall has made a considerable difference to the internal temperature, the sun has been beating down again today and the highest recorded reading was 27°C, a far cry from the 42°C seen previously – this is without the extraction fan that I’m going to fit, drawing out hot air from the roof space. Saturday evening was clear again so I had the chance to capture the OIII and SII data to finish off the wide field Sadr region, IC1318. I captured 30 frames in each filter plus a new set of flat frames for the OIII, I don’t seem to need them for Ha and SII – here’s the finished image.
Dark and flat frames used, processed in Deep Sky Stacker ( DSS ) and Photoshop CS5.
