The classic edge-on spiral, the Sombrero Galaxy, Messier 104, in Virgo. This object is always low in my home sky so tough to get a clean, sharp image of it, but this night, April 20, 2020, was as good as it gets for me. It looks like there is a little asteroid trail to the left of M104. I left it in. This is a stack of 6 x 10-minute exposures with Astro-Physics 130mm apo refractor at f/6 (with the 6x7 field flattener) and Canon EOS Ra camera at ISO 800.
The Sombrero Galaxy, Messier 104, in Virgo. This is an object low in my home sky but taken on a fairly clear spring night, April 23/24, 2022 as part of testing the Sky-Watcher Evolux 82mm telescope. The field of view is 4.3° by 2.8°. This is a stack of 15 x 6-minute exposures at f/5.8 with the Evolux 0.9x reducer (so 475mm focal length) and Canon EOS Ra at ISO 800. Sub-frames dithered with MGEN3 auto-guider. No darks applied. Residual chromatic aberration removed with Camera Raw Defringe.
