Description

Tried something new this morning, what else to do at 6am on a Sunday morning

Taken with my 294MC Pro and L-Enhance, I reprocessed my NGC 7000 data for HOO. I say HOO, but it's more SHO, however the Sii channel wasn't used.

Processing details:-

After my usual stacking and back ground extraction, I extracted the 3 channels Ha, Oiii and Sii. Sii was thrown away. I then used linear fit to match the Ha levels to the Oiii. I carried out some noise reduction on both Ha and Oiii (Oiii more so as it was noisier.

I then combined the 2 using pixel math with Ha to Ha, Oiii to Oiii and made a synthetic Siii using 0.2 x Oiii + 0.8 x Ha. I then stretched the image, did some colour calibration, star reduction, more noise reduction and finally exported to Lightroom as a TIFF.

Hope you like it
