Clouds, wind, and rain prevailed on the East Coast.
While I was planning future astronomy sessions, I rummaged through my hard drive and found this image from March of this year.
It's the Sombrero Galaxy, M104, and it's one of my favorites.

The imager that I used was my ZWO ASI224MC.
The image was created using electronically assisted astronomy techniques. I used SharpCap to perform the image capture and used its live stacking capability. Exposure time of each frame was only 2 seconds and 110 frames were stacked.
So, this image was fully formed in 220 seconds. No post processing necessary. I just selected "Save as viewed" from SharpCap's live stacking menu.
While the image is pretty, it does illustrate one of the shortcomings of my imager. Some of the stars are bloated. This is a consequence of cranking up the gain and the exposure time so that dimmer parts of the object can be seen -- parts of the object and nearby stars are overexposed.
I'm thinking that I need to upgrade from this imager to one that has greater sensitivity, a "deeper well," and a greater field of view. 🤓
If I do this, I will need to revisit all of the objects that I've ever imaged and do a compare and contrast analysis . . .
Next time? More Mars? I want to capture lots of Mars images as it shrinks into the distance from us.
