M106, Spiral Galaxy in Ursa Major
Chasing all of the Spring Galaxies before they get away for another year. Who knew M106 had so many friends? IDs of the dimmer galaxies TBD. 90 minutes of exposure time brings […]

The galaxies around Ursa Major have been providing me with lots of opportunities to work on shooting stuff near the limit of the image scale I can really produce with Veronica and […]

M101, The Pinwheel Galaxy in Ursa Major
I attempted another 1-hour integration of M101. I think this really needs more integration time. I might be able to combine the hour from February and the hour from May into one […]
