I have long ago exhausted my own pool of data and are waiting for astrodarkness to return in a month or so. Fortunately, the group of Norwegians that has set up the SkyEye remote obsy in Spain (see
https://www.astrobin.com/users/SkyEyE/) has kindly let me work on their excellent Ha and RGB data of IC405 collected in February. Thanks a lot guys!!
I put extra emphasis on the blue central structure making sure it did not get overwhelmed by the strong signal in the red and Ha channels. I did not use the Lum data provided as the stars in the Ha and RGB data looked better. Instead I used a bit of Ha as Lum (Ha also mixed 50:50 into the red channel). Aligning and Deconvolution in PI. All the rest in PS CS5. I also made an experiment of only processing the green and blue data to see what it would look like without the Ha/Red signal (although I added RGB data to the stars) and I post that one separately.
Info: TS Optics Photoline 130 f/6.62 with a Moravian G3-16200 on a 10 Micron GM2000 HPS II. Focal reducer:APM Riccardi 0.75x. Astrodon Blue Tru-Balance E-Series Gen 2: 25x300", Astrodon Green Tru-Balance E-Series Gen 2: 25x300", Astrodon Red Tru-Balance E-series Gen 2: 25x300", Astrodon Ha 3nm 50mm: 190x300". So totally 22.1 hours.
Comments and suggestions most welcome of course. It was for example quite difficult to decide how dusty I would make the image - the Ha data contained a lot of it.
