NGC2020 - Narrowband
Planewave CDK 431mm F6.8, FLI Proline 16803
5 x 600s in H-alpha
6 x 600s in OIII
3 x 600s in SII
All bin1x1, processing and editing done in PixInsight 1.8 and final tweaks in DxO PhotoLab 2.
Color palette mixing ratios aren't Hubble but something close : blues are oxygen, oranges are hydrogen, reds are sulfur.
Back in late September and early October 2018, I booked T32 in Siding Spring Observatory (Australia, part of iTelescope.net) over 3 nights to image a small part of the Large Magellanic Cloud through narrowband filters.
The telescope performed moderately well with some images slightly out of focus, but the most difficult part for me was dealing with column defects on the CCD sensor. I tediously listed 73 by hand, and some of them still show up after processing ... I was hoping to find the energy to find a solution and re-do it all, but after 6 months I give up ...
