The California Nebula by ARTstronomy retailer *GLASS*

This may be my new favorite. It's 145 minutes (29x300 seconds) worth of narrowband data (H-alpha and OIII) of the California Nebula (NGC1499). This emission nebula is glowing, thanks to the bright O star in the upper left retailer portion of the image. All data captured January 30, 2022.

Acquisition equipment used included a William Optics Redcat 71 telescope and a ZWO ASI183MC Pro and Optolong l-Pro narrowband filter. The telescope was mounted on a Sky-Watcher EQ6-R Pro Mount, and was autoguided using an Orion 60mm Guidescope and a ZWO ASI120MM Mini guide camera.
