Sh2-234 IC417 The Spider and Fly Nebula

These two nebula are often over shadowed by their more frequently imaged neighbours (Flaming Star and Tadpoles) or often captured with a widefield view of this magnificent area of sky, losing their intricate detail. There are plenty of spiders in my obs too, time for a winter clean sweep!

About 10,000 light-years distant, both represent young, open star clusters formed in interstellar clouds and still embedded inglowing hydrogen gas. For scale, the more compact NGC 1931 "The Fly" is about 10 light-years across.

Captured with my WO FLT132 at F5.6; 10 Micron GM1000HPS; QSI683-wsg ccd' Astrodon 5nm Ha and LRGB filters; 12 x 1200s subs Ha, 12 x 300s each RG&B for a total of 7 hrs integration; December 2016.
