M64, The Black Eye Galaxy in Canes Venatici
After 4 overseas trips in 4 months, I finally had some time to really get some time under the stars and get back to the “spring” galaxies that I’d raced to catch […]

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, […]

NGC 2403, Spiral Galaxy in Camelopardalis
This was the second night out with the Gemini. I decided to take the GOTO out for a spin. It did well. *Very* well. I punched up NGC2403 because my DSC program […]

M101, The Pinwheel Galaxy in Ursa Major
I tried for 2 hours on M101, but ran out of time at 90 minutes. This isn’t a particularly spectacular image, but it’s unguided, and the GOTO was working like a charm […]

M51, The Whirlpool Galaxy in Ursa Major
First light for my brand new Gemini mount. M51 is quickly turning into “the M42 of spring”; an easy to shoot, easy to find target that distracts me from other nearby objects. […]

M106, Spiral Galaxy in Ursa Major
Another first-light image from the Gemini. I was having fun with the GOTO on the Gemini. It was bringing up targets really easily. I decided to try this big galaxy, to see […]

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 […]
