NGC891 (Silver Sliver Galaxy) last night, 80% of 160x180s exposures. First test of the new ASI2600mc pro with replacement fan deployed (see prior post). More info on this target here: en.wikipedia.org/wiki/NGC_891. A definite improvement over those elongate stars I was getting from imbalanced fan.

1/2: PSA: Do you get oblong stars like this but have good guiding? Are you using a ZWO cooled camera at long focal lengths? Is the elongation independent of exposure time? The problem is likely an imbalanced fan in the camera (in my case a brand new ASI2600mc pro).

Here is another screen capture this morning from the Mauna Kea Live webcam. Lasers are used to create an artificial laser guide star used for correcting for atmospheric turbulence. This technology is called adaptive optics and is a crucial tool for modern ground-based astronomy.

This morning, I brought up the webcam at the Subaru Telescope, Mauna Kea, HI. The image was spectacular, so I am sharing the screen shot I took. Here is a link to that webcam for those interested. www.webcamtaxi.com/en/usa/hawai...

An amateur star-gazer’s pain,
Who wished for the skies clear again,
Sat watching the rain,
With a hopeful refrain—
“Let me glimpse through this clouded domain!”

M81 (Bode's Galaxy) this morning. I had an hour to kill before sunrise so gave it a shot. 48 minutes total exposure in Bortle 6 light pollution. Just tossing this out as an example of squeezing in all the dark you can in an imaging session. A "shot in the dark" maybe?

After a bit of a hiatus from astrophotography, I gave my new camera (ASI2600mc Pro) a spin around the block last night (09/17/2025). Here is M31 (Andromeda Galaxy) with very little post processing. 120 X 180s exposures (stacked best 80%). C9.25 Edge with Hyperstar V4.

For something different, and good for a change! There has been a die off of starfish on this particular section of Oregon coast over the last few years. I am very happy to report that they are making a comeback. But slowly. Lessons learned. There is really hope for lost causes.

No surprises there. Russia has invested in Little Marco and they expect something in return.

A brain-cleanser after witnessing that vanity parade yesterday. Tide pools on Oregon Coast taken a few days ago. Evolution suggests that at one time in the distant past, we crawled out of these. I am thinking at this point that we did not get far, but I remain hopeful.

I just finished up a third night on M82 (Cigar Galaxy) en.wikipedia.org/wiki/Messier.... About 9.5 hr. total exposure. I then applied the Hubble Ha-OO palette to the final image and did a comparison. My image on the left, a Hubble image on the right. No complaints but I now want an orbiting scope!

This is M27 (Dumbbell Nebula). Six-hours total exposure from my backyard on 05/07 and 05/08 2025. M27 is a planetary nebula (nebulosity surrounding a white dwarf) at a distance of about 1360 light-years. Dual narrow-band filter and Ha-OO Hubble palette. More here: en.wikipedia.org/wiki/Dumbbel...

The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula approximately 2,030 light years away. Estimated to be about 8,000 years old, it was formed from the outflow of material from the stellar wind of the central star. Six-hour exposure on 04/21/2025 from my backyard.

This could be an image of your 401K blowing up, our economy blowing up or our democracy blowing up. Nope. It is Messier 3 (NGC 5272), a rather spectacular globular cluster consisting of a half-million stars. Took it last night. Here is more info on it. en.wikipedia.org/wiki/Messier_3. Stay strong.

This is M100 (The Blow Dryer Galaxy) It is 55 million light-years distant. The light that hit the camera sensor started its journey at the same time that Earth was undergoing mass extinctions in the oceans due to global warming. History may repeat itself. en.wikipedia.org/wiki/Messier...
