Hi all,
I managed to gather just 4 hours of Ha data a few weeks ago in a momentary break in the smoke haze. This is the first light with my new ZWO183MM-Pro and 7 position EFW with ZWO narrowband filters. I realised I haven't got the spacing between my new OAG and the camera quite right. I managed to get them both to come to focus by adding a spacer between the OAG and camera but it is too wide so the camera comes to focus pretty much at the zero position. This meant I had to manually focus. I'll grab a set of spacers from Bintel after the new year to fix that issue.
The details are:
Gain - 111
Offset -10
Temp - -15C
48x5 minute subs
WO Star 71, CEM40, ZWO183MM-Pro, ZWO 1.25" 7nm Ha filter
I can't wait to get more data on this target.
