FocusMax – relearning the V-curve

M104, The Sombrero Galaxy in Virgo
Finally! A Virgo galaxy. I’ve had some kind of mental block about shooting in Virgo, so I finally forced myself to shoot down here. M104 is on the edge of being too […]

M81, Spiral Galaxy in Ursa Major
Like M42 is a “tester” object for winter, M81 is a tester object for the spring. It’s big and bright and there’s lots of detail to bring up. In addition, if well-framed, […]

M82, Spiral Galaxy in Ursa Major
This is a “freebie” version of M82. It was way off in the badly vignetted border of the above M81 images (M81 was centered). But once I applied flat frames to the […]

M63, The Sunflower Galaxy in Ursa Major
This time I went nuts and punched up 4(!) hours on M63. That’s by far the most I’ve ever done. This was unguided, while I was still testing out the new mount. […]

M81, Spiral Galaxy in Ursa Major
I decided to quit messing around with trying to get both galaxies in the field at once, and just concentrate on getting a good shot of M81. This is a 3-hour integration, […]

Dome shutter is motorized again!
I finally decided to bite the bullet and fix the shutter motor. Things went sideways last winter, and I’ve been opening the shutter manually (and tying it shut with rope, so we […]
