NGC 7380 and the "Wizard Nebula", start of the new project





NGC 7380, Sh2-142 , the "Wizard Nebula", locates in constellation Cepheus about 7000 light years from Oulu, Finland. The open star cluster has a catalog number NGC 7380. It's a relatively young cluster, about 5 million years. Nebula spans some 110 light years.

There is only 1h 20 min. H-a light for the object, due some technical problems. Ones again, I spend most of the night by fixing my ***** scope.
Seeing was better than usually, FWHM about 2,5".
I'll shoot much more H-alpha data and other NB channels, S-II and O-III later.
Image is very noisy due the short exposure time.

Technical details:

processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Levels and curves  in PS CS3.

Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 6Hz
Image Scale, 0,75 arcseconds/pixel
Exposures H-alpha 4x1200s, binned 1x1
