Tadpoles are twisted trails of interstellar matter in the IC410 hydrogen cloud. In the same moment these are must have in every astrophotographer portfolio. In this season I decided to make up on this target as well. But not in usual HST narrowband palette, because I am missing Sii filter (there is photometric V filter in my wheel). So I figured out HaOiiiRGB composite, and you can see the outcome below. In the foreground in the middle of the frame you can see NGC1893 open cluster that is responsible both for the shape and for excitement of the IC410 hydrogen cloud.
I collected photons to this image in December 2016 and January 2017. It is total 360 minutes of hydrogen alpha band, 200 minutes in oxygen III band and 3x12x3 minutes of RGB frames. All made at my suburban backyard with 130mm refractor and QHY163M camera with EQ6 mount.
