Description

Here's an Ha shot of Simeis 57, known as the Propeller Nebula, for apparent reasons. I was aware of it in the wide field Borg image of HIP 99749, and elected to capture it with the 132. Shot over two nights after Cygnus had transited, the 3.5nm Ha filter delivered great data despite a very bright Moon. I will wait for Luna to not be a factor to collect OIII and SII data for future renderings.
