NGC 2174, Emission Nebula in Orion
One of those objects that just doesn’t get much press. This is a huge nebula, the size of M42, and well-placed in the sky, between the foot of Gemini and the head […]

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, […]

B33, The Horsehead Nebula in Orion

Special Guest Star takes the mount at Hilltop O
The Astro Jedi needed somewhere to store his light sab—- I mean, bucket, and I was only too happy to accommodate him. I have decided that I need to come to a […]

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 […]
Trixie 2017 – tube mods
I finally got around to cutting the MTA-UTA tubes to length; the only eyepiece that would come to focus with the focuser spacer in place is the Televue 55mm Plossl. If I […]
