Sh2-101

Popularly called the Tulip Nebula, the glowing cloud of interstellar gas and dust in Cygnus is catalogued as Sh2-101. It is about 8,000 light-years away and 70 light-years across.

I started imaging this target towards the end of M20 data acquisition marathon. I wanted to capture details of its core and the bow shock at 2350mm focal length so I opted for a 2 panel mosaic. With bortle7 skies, I needed a large integration across both panels at F/10 speed. In the end, I had to crop almost 50% of the top panel because signals were weak there and not contributing to the overall image. May be next year I will collect more data of the top panel and also more panels towards the right to complete bow-shock.

It was a very long project. I hope you will like it
