Deep Sky / Long Exposure Photography
Two targets, all 20m subframes, woot!
Thus begins a new era. First, a little history. When I built the observatory in Newark, CA, the light pollution was so bad that the sky never got darker than about brownish-pink […]
Deep Sky / Long Exposure Photography
OK, I need to stop shooting 5m subframes.
I decided to go after The Owl Nebula, as I’ve only gotten one shot of it previously, despite years of hunting in Ursa Major. So I caught half an hour of it, […]

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 […]

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 […]
