My last astrophoto was of IC405, also known as the Flaming Star Nebula.  IC410 is a close neighbor of IC405 – a bit of it is showing at the edge of the IC405 photo.  This nebula is best known for a small feature near the center, known as “The Tadpoles”: Most of the data for this image was captured near the full moon, and even though it is all narrowband data (using 3nm filters), the moonlight and haze made the O-III frames pretty bad.  The S-II frames were also less than ideal, so I leaned heavily on the H-a data […]

Tadpoles in Space!

IC410 is an emission nebula in the constellation Auriga, and best known for the two little squiggly shapes that look like tadpoles.  It’s an interesting target at various degrees of magnification.  At very high magnification (and better atmospheric conditions than I ever see here) you can frame just the tadpoles.  A slightly wider view would include most of the surrounding nebulosity.  This view is a bit wider yet, to include some of the extended nebulosity below and to the right of the main portion.  A very wide view could include several other nebulas (see https://wa-chur-ed.com/ic405-410-and-417/). I captured this image in […]
