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.
