Another reference image with the SW120 Esprit.. I really need to go back to PSD to mix in Ha with galaxies. My attempt to do so in PI is lacking. This was again at the native F/7.2 from a pretty bright suburban location. Almost can get into the faint clouds.. Thinking that next year the 6120 camera will make that a bit easier. Of course heading to a good dark location make sense too. Hard to leave the comforts of home.
Just trying to learn some new tools! This version had the RGBL masters built using LocalNormalization tools in PI. Also, rather than adjust color using spiral directly as white reference I used PhotometricColorCalibration tools. No Ha in this one at all.. 81x300L; 26x300B; 27x300G; 32x300R.. Black point a bit high to show all the dust in the region - somewhat poorly..
Another pass with PCC color calibration. Better noise reduction and a bit darker. Also got a little more saturation in the galaxies. No Ha data.. This was 81x300L; ~30x300RGB. SW120 F/5.2 with Riccardi 0.75 reducer. Gotta gt to a darker location to best show the dust.
