¾ Moon, Moonset at 02:15
Location: Trier, Germany

Equipment:
Telescope: TMB 92 SS f/5.5 with TSFlat, with dew heater
Mount: CGE, selfguided with ST-4000XCM
Camera: SBIG ST-4000XCM
Filters: Baader H-a 7nm

Acquisition:
Software: CCDSoft V5
FOV, Image scale: 102.8 x 102.8 arcmin, 3.01 arcs/pixel
Sub-exposures: 1h 20min (8 x 10min) light frames at –30°C,
50 x 10min dark frames

Processing:
Calibration, stacking, extraction L-channel in Images Plus 3.75,
curves and levels adjustments in CS3, noise reduction with Carbonis Actions,
SMI enhancement and High Pass sharpening in CS3

Comments:
This is the first attempt to make a H- image with the TMB under high Moon conditions.
Too short exposure time. Only through the SMI technique it was possible to bring the
details of the nebula.
