Hi all,
I have a new ASI 1600 MMC Pro. Do not you know why are there horizontal lines (and diagonal) at short exposures (FlatField) ? Sample - attachment in jpg...
- Without flatfield panel is the same - bad
- Without filter wheel is the same - bad
Setup:
- native driver ZWO for ASI 1600 MMC Pro
- Sequence generator Pro
- exp. 0.32 s.
- driver setup
- highest dynamic range - default, USB Limit 40
- stretch in Pixinsight
- flatfield panel - https://www.gerdneumann.net/english/astrofotografie-parts-astrophotography/aurora-flatfield-panels/uebersicht-aurora-flatfield-panels-overview.html
