Galaxy NGC 4274
NGC 4274 is characterized by its overlapping outer arms, forming a ring structure. The inner arms begin near the edge of the bulge and they are bright and dusty, with dust lanes that more prominent at the near side. Outside the near-ring a set of fainter outer arms. These outer arms also form a ring. A third rings exists near the nucleus.

Solar Halo
EarthSky.org states that, “That’s why, like rainbows, halos around the sun – or moon – are personal. Everyone sees their own particular halo, made by their own particular ice crystals, which are different from the ice crystals making the halo of the person standing next to you.” (ref: https://earthsky.org/space/what-makes-a-halo-around-the-moon).

Sirius and the Pup
The snapshot shown was taken from inside SharpCap (v3.2) using a GAIN of 109 and exposure setting of 0.986 seconds. To help confirm this was the companion to Sirius, the camera was rotate to make sure the Pup rotated with the camera.
Using the CCD Calculator tool from Astronomy Tools (https://astronomy.tools/calculators/ccd), the resolution of the photograph was calculated to be 0.2"/pixel (using a 2.9 um CCD pixel size and a 3,048mm focal length). Measuring the pixel distance from the center of Sirius A to what I believe is Sirius B shows a calculated distance of 12.6 arc seconds, which is close to the predicted 11.193 separation provided by Stella Doppie.

The Dog Star and the Little Beehive Cluster
Located 4-degrees south of Sirius is the open cluster Messier 41 (M41). M41 has an apparent magnitude of 4.5 and is about 2,300 light years from Earth. M41 is also referred to as the Little Beehive Cluster, but I can’t find the exact reference. M41 was mentioned by Aristotle about 325 B.C. as one of the mysterious “cloudy spots” then known in the sky. (REF: Robert Burnham Jr., Burnham’s Celestial Handbook, 1978).

Meteorite Impact During Eclipse
There was some discussion after the recent total lunar eclipse about a possible meteorite impact occurring. After scrubbing my data, it looks like I captured it around the same time as it was reported. I haven't read anything recent confirming the impact, but thought I would share the images/dates/times so you can check your data.
