Still Testing the AM5

August 20, 2022

Here's the Tulip Nebula (Sh2-101), top center, and some of the surrounding cloud structure in Cygnus. This is 23 x 240 second (4 minute) exposures in Hydrogen-alpha (6nm Astronomik narrowband filter), no calibration frames. I'm still testing out the new ZWO AM5 mount, and the Tulip is a nice deep sky target for Ha. Gear notes: William Optics SpaceCat 51 Apo refractor, ZWO ASI1600MM-Pro cooled monochrome camera.
