More mono learning fun; 1st (OSC) Helix was this time last year. After seeing John's (Oksa) recent RGB Helix I felt inspired as I thought the Helix was a purely NB target, not BB. So here is 11h 33m of Helix data which includes 7h 45m RGB and the remainder is Ha; the Ha was used as luminance and Ha proper. Twas integrated in APP and processed using PI's included noise reduction (TGV, MMT) and sharpening (deconv, MLT) tools and other histogram/curves tools ... final output had a light touch of NoiseX before some small tweaks in PS.
Love the cometary knots (globules) that are visible in the heart of the nebula. The background contains many little galaxies that some L data will (hopefully) bring out; I have more data to collect.
Details are: EdgeHD 8" with 0.7 R, ASI294MM, Antlia RGB, Optolong Ha
R - 54x180s = 2h 42mor
G - 54x180s = 2h 42m
B - 47x180s = 2h 21m
Ha - 76x180s = 3h 48m
