Here is a 140 minute H-a image of the Tulip Nebula.

Seeing was incredibly steady, about Pickering 5. That is extraordinary for my Northern Illinois site!
The image was taken with a Takahashi E-160 (f/3.3) astrograph aboard an AP-1200GTO. The camera was an SXV-H9, and the exposure was 14 x 10 minutes. Guiding with an MX-716 and NP-101. Astrodon 6 nm FWHM H-a filter. Acquisition AA 3.0, processing in ImagesPlus.
Thank you for visiting my site.
Clear skies,
