I am attempting to work my way around Cygnus, and intended to shoot the region near Sadr (IC1318). This region is large enough that even Pumpkin can only capture a piece of it. Rather than swing around “in the dark” to find the particular chunk I was looking for, I tried to do a web search to find widefield shots of the region, so I could aim more appropriately.
While looking, I ran across a photo of Sharpless 101 (Sh2-101), also known as The Tulip Nebula. There was some interesting nebulosity around the bright region, so I decided to try my hand at this object. Luckily, the Gemini has the Sh2 catalog onboard. So I pointed to the proper section of sky, laid in a sequence of 20min subframes long enough to keep running until sunup, and went to bed after it got started.
I woke up to a screaming mount (it goes beeeeeeeeeeeeeeep when it hits its “safety limit”), turned it off, and went to work. When I got a chance to process this image, this is what I had:
I love my Ha filter. 🙂
Another night, another ton of wispy yummy hydrogen clouds in the summer Milky Way.
