Jellyfish nebula

Here's an image taken using the Dwarf3 in alt-az mode. I programmed in an unattended sequence last night lasting 3 hours using the duoband filter. I did boost the gain to 180 to help with the nebulosity.

This image was created from around 640x15s subs. I haven't got to grips with the eq mode yet. There was substantial rotation but the Dwarf produced a reasonable stack at the end of the process. Fortunately it has a large field of view, over 2 degrees in width, so I was able to crop out the low signal sections.

I restacked the subs in FBPP and then processed the master in Pixinsight. I can see a hint of the nebula at the head of the Jellyfish, which I haven't managed to get before.
