Description: This image is processed from a completely new subs captured with my brand new Chroma SHO 3nm filters. Although the total integration is only 4 hours, the difference in overall contrast and stars size is impressive compared to the previous versions (A and B) captured using old filters with 14 hours integration time. In addition, there is no halo around Propus (Eta Geminorum) star. Last 6 Ha subs are captured under almost full Moon.

Description: More SII exposures were included in this image and drizzle integration was applied. Total integration is now 6 hours.
