Deep Sky / Long Exposure Photography
IC1396, Emission Nebula in Cepheus
Sometimes you luck out when you’re “just testing”. I am still shaking out the kinks in my 350D workflow. I put the Ha filter back on the 350D last night. Focusing with […]

NGC7000, The North America Nebula in Cygnus
This is my first HaRGB shot. It’s a combination of grayscale luminance data that I captured while camping at Coyote Lake, CA over the weekend, and color data that I captured from […]

NGC7000, The North America Nebula, from Coyote Lake, CA
This is my deepest image yet of NGC7000, 5 full hours (15x20m). This is with my normal Levels-and-Curves treatment in Photoshop, but it’s the full FOV. This was first light for my […]
Long Exposure Photography / Techniques
Coyote Lake widefields
It is hard to describe how much fun I had shooting widefields from the tripod. A lot of the shots came up out of focus, and several more came up with star […]

NGC281, The PacMan Nebula in Casseiopeia
This is my first shot of NGC281. I attempted it a couple of years back, but came up essentially empty. Normally, the Casseiopeia Milky Way is not available until autumn, but I […]

NGC 6888, The Crescent Nebula in Cygnus, from Coyote Lake, CA
In retrospect, I probably should have shot RGB from the dark sky site and left Ha for the backyard. In addition, it was very windy, so I probably should have dumped Cassie […]

M57, The Ring Nebula in Lyra
The C9.25 finally brings some pixels to this tiny object. Shooting with a DSLR brings a different perspective on “useful astronomy targets” compared with most dedicated astrocams. In the beginning, there was […]

NGC6939, Open Cluster in Cygnus
Again, Cygnus is not really my first thought when it comes to open clusters (at least, not ones that seem to have no nebulosity surrounding them). But this cluster could rival anything […]

NGC6946, Spiral Galaxy in Cygnus
Cygnus is not generally the area of sky you think of when you think “hey, showpiece galaxy”. But here you go. NGC 6946 has been dodging me for years, so I decided […]

NGC4565, Edge-on Spiral Galaxy in Coma Berenices
Normally, I don’t go in much for edge-on galaxies. I just don’t think that I really get enough pixels to work with for the amount of effort that goes in. But NGC4565 […]

Polar Alignment Calculations
Here’s a page that derives Polar Alignment Calculations. (update 5/2020: the original site is gone, so I found the text on Wayback and am inserting it below. This is by the original […]

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 […]
