Description

This is one of the images where I don't know what to do with it. I've captured the data for this object during a single night in April 2023. During that session, I was experimenting with a new capturing and control software (no names here but let me assure you that these experiments convinced me to stick with NINA) and so I had some struggle capturing the data properly, which leads to an imbalance in the color channels w.r.t to the amount of data. Nevertheless, as we'll see that's less of an issue as one might expect.

What are we seeing here is NGC2681, a galaxy about 12.5 Mpc away from Earth (according to NED). From its shape, it's called a lenticular galaxy, which is a class of galaxies between spiral and elliptical. Based on the distance, it's diameter should be approximately 55 kLy. Researchers dispute how many spiral arms one might identify in this object (I guess there's a positive correlation between good will and number of spiral arms). The object has been studied with the HST but not in all visible wavelengths which would permit the development of a comparable color image.
The galaxy doesn't seem to show a significant color tint except for the core region with a typical yellowish/reddish tone.

With respect to my image, might place the argument that more data might have helped, but it turns out that this object isn't Miss Universe from an aesthetic point of view. Reference images here on AB (not so many actually) and also over the internet show that the detail lies in the luminance channel and only in a form that you'd need HST or a large scope with adaptive optics to show details in the galaxy's core. Therefore, multiples of the collected data might not push it over the finish line. Hence the title: What to do with the image? Trash it? Push it (in the sense of more data)? or Show it?

I finally chose to show the object as only few here on AB ever captured it and so at least it contributes to the collection of possible "reference" images.
