Please take a look at the revised last paragraph of the sidebar to the right. To see what I’ve been up to lately with Stella the telescope (and with several of her big sisters around the world), click the Astrobin link there. Astrobin makes it easier for me to share not only my “finished” images […]

The pinwheel galaxy, whose proper designation is Messier 101, is not an easy object to photograph. It has little color, and efforts to boost the color that it does have usually ends up ugly. This time around I photographed it remotely using a 20-inch telescope at Mayhill, New Mexico, at 7,300 feet. Total exposure for […]

Mr. Pacman, AKA NGC 281, now has on his varicolored coat. Ain’t he pretty? Technically, this is a conventional LRGB image with the luminance (L) component replaced by the black and white hydrogen-alpha image shown in the previous post. I made 69 separate exposures totaling 7.5 hours of exposure time. Click on the image to […]

This deep space object is officially classified as NGC 281, but many know it better as the Pacman Nebula. It is rich in Hydrogen emissions, and this shot represents an exposure of a little over 2 hours through a narrow-band filter passing only the Hydrogen emissions. It makes a nice black-and-white photo, I think. Color […]

This is the last gasp of 3″ telescope Stella from my light polluted back patio until next spring. A dozen exposures through each of three narrow-band filters did a pretty good job of ignoring the light pollution from nearby parking lot and street lights and capturing the emissions from narrow bands of the visible spectrum […]

The little patch of sky I call the Sadr neighborhood has a lot going for it. It is not only positioned conveniently for me to view, but it sports a nice bright star (Sadr, or Gamma Cygni) plus some interesting patches of nebulosity. On the other hand, photographing it has been a challenge for this […]

Way up there in the eastern sky somewhere is a star named Sadr. I can barely make it out through all the light pollution, but I know it’s there, because my trusty telescope Stella dutifully bores a hole for me through the polluted atmosphere so I can peer into outer space. Even better, if I […]

The Pinwheel Galaxy is a popular target for amateur astrophotographers, and I am as about amateur as they get. For this shot I hired a telescope owned by iTelescope.net, located at Mayhill, New Mexico. Over three nights I collected several hours of red, green, and blue data. These were fed into the PixInsight processing program […]

This image was taken from Maui, Hawaii, by Dori Thorngren, my sister-in-law. She says, “Aloha! I used a Canon Rebel with a 75-300 zoom on a tripod. I took it at f/5.6, 1/3 second, ISO 1600, from our front door entrance. We started our viewing by watching the moon rise through clouds from an oceanfront […]

This should be the low point of my telescope mount Hypertune project. Everything has been taken apart, and the next step will be to smooth and polish the moving parts, apply fresh lubricant, and re-assemble them. My goal is to not have any parts left over or come up short at the end. And of […]
