Reprocessing Owl and Surfboard Galaxies

I captured this early 2020 with my ZWO ASI183MC OSC.

Pixinsight have just released WBPP 2.2.0 and I thought I would run some old data through the new script to see what it could do. One of the features is to split the RGB image into separate greyscale frames and align all 3 channels to avoid the colour fringing you sometimes see at the edge of field - especially on scope like SCTs which sometimes show red fringe on one side of a star and green on the other side.

So I ran the Owl and Surfboard (I think it is also called The Hockey Stick Galaxy too) and was pleased with the results.

 

Camera: ZWO ASI183MM

Telescope: William Optics ZS73 with 1:1 flattener

Filter: IDAS D2

Frames: 92 x 240 seconds 6.13 hours

I believe the Hockeystick NGC 4656 is a different galaxy Terry, usually associated with the Whale galaxy NGC 4631 in Canes Venatici.

 

You captured a lot of detail in the galaxy, the bar across the Owl is clearly visible also, reminds me of a button.
