IC342, an invisible object

IC342 is a large, bright, nearby galaxy that would be “naked to the invisible eye” if it weren’t for the dust in the way.

Here’s a five-minute exposure, with a gratuitous satellite:

Do you see a galaxy? Maybe if you squint and sacrifice a pint of Haagen-Dazs?

But curiosity — perhaps more exposures could tease out something?

Here are 41 images like the above, stacked up and combined:

It looks like a galaxy! I should note that these images were taken on a night with excess moonshine, in hazy suburban skies.

Three of the 41 exposures had satellite trails, but they disappeared in the average.

There is an overall red tint to the photo. It’s probably not natural, but rather an artifact of the anti-pollution filter I am using.

Markarian’s Chain, most of it

There are many more galaxies that I can’t resolve.

The cluster extends widely past this field of view.  Poor framing — if I had tilted the camera I could have included more of it, and the “chain” moniker would have been more obvious.

Oh Dear, NGC3718 yet again

Well, I managed to collect a few more photons from NGC3718, and the result is marginally better. Marginally: the black of space is a bit smoother:

I can skip over to Google and find a hundred images of this object with more color and detail, but the process of collecting light in the cold dark yourself makes it all real.

Here’s an annotation of a less-processed version:

The dust in NGC3628 is more evident in this version; in fact, details are better throughout. I haven’t quite figured out why.

I collected all of the sub-images during bright moonlight. Maybe in a week or two, I will post a better rendition. This picture has just a hint of whispy spiral arms at the edges, which I might be able to capture.

Gold and red swirley photo
Happy accident.

Was this deliberate? I don’t remember. Something was moving, and something wasn’t.

The grain in this grayscale image is an accidental discovery, and it reminds me of pictures shot with Tri-X many years ago.

I used to push Tri-X to ISO 800 or 1600 in my little Olympus OM-1. I liked the grain, and more, I enjoyed the freedom of taking pictures in dim light.

I took this picture a couple of weeks ago — my first visit to the Valley since before the pandemic. It’s winter, and it is a little threadbare and worn. But there are still climbers on El Cap:

My wife says sometimes that she would like to be reincarnated as a rock. I’m not sure about the mechanics of that, but here is a nice rock:

One could let the fever dreams of twisted humanity flow by; in a few hundred thousand years they will resolve.

Black Eye galaxy

Here is a small target for my telescope. The “black eye” is discernible, but only on close examination can any other structure be seen. It’s sometimes called the “Evil Eye” galaxy; this Hubble View makes that case very well. The idea that there are two counter-rotating stellar populations is mind-boggling.
