what have i done wrong with this image?
this is a shot of the horsehead. it is my first time with flats and bias frames. this has been stacked in DSS and processed in PS. i am learning to drive DSS and PS.
6x 15 min exposures
6x 15min darks( in know i need more)
10x flat
10x dark flats
10x bias
i experimented with different settings in deep sky stacker. but did not keep a very good track on all the settings. the thing is that this image has tonnes less noise than the other stack settings except it seems to have this overlapped rectangular frames at various angles. any ideas what may have caused this, as i am very happy with the image(compared to the others which were way noisier and seemed to suffer vignetting despite the flats) or what DSS settings to use.
i stacked with a mosiac setting
\median kappa sigma clipping
dark,flat and bias left on average
alignment on automatic
