Equipment: Telescope: TMB 92 SS f/5.5 with TSFlat2.5 Mount: GM2000QCI Guiding: Orion Short Tube 80mm with ATIK 16 IC-S Camera: SXVF-M25C Filter: IDAS LPS
Acquisition: Software: MaximDL 5 FOV, Image scale: 107.5 x 159.6 arcmin, 3.18 arcs/pixel Sub-exposures: 5h 50m (35 x 10min) + 4h 30m (27 x 10min) + 5h 15m (31 x 10min) lights Calibration frames: 50 x 20s EL flats. Masterbias
Processing: MaximDL 5: Calibration, SDMask stacking CS5: Mosaic construction, Curves and levels adjustments, GradientXterminator Comments: This picture is a horizontal mosaic of three shots. The weather during acquisition of the left part of the mosaîc was quite bad, so the quality is poorer than the other two parts. In general the picture is a bit noisy and more signal would have been necessary. This is my first experience with mosaics.
