Description

Sharpless 171 acquired across several nights in SHO, blended with one night of OSC stars for good measure. This is a cropped in version of my NGC7822 post.

This is first light on the new ZWO ASI2600MM Pro and the Antlia 3nm filters, including my first ever image processed from SHO data.
