IC 1727 and NGC 672 in Triangulum (Michael Feigenbaum)

IC 1727 and NGC 672 in Triangulum

Here we have a crack at this very nice pair of galaxies located in Triangulum, IC1727 and NGC 672. These two galaxies lie about 24 million light years away and appear to be interacting. NGC 672 is a barred spiral and IC1727 is somewhat irregular which may be because of the interaction with NGC 672.

I imaged these over the last month or so as time allowed and decided to try to do some Hα integration to see if I could pull out any of the star forming regions. I used the popular continuum subtraction technique of Vicent Peris to see what I could do with this but with one difference. I decided to subtract the luminance data from the Hα rather than just the red channel because I reasoned that it might be more effective in isolating the signal. It seemed to work OK but still, this is a rather small set of objects, both being about 6 arc minutes wide and so resolution with a 9.25" telescope might be a little bit lacking.

I tried to be very conservative with the color in this one and really, I was not all that pleased with the color in an overall sense. But still, an interesting set of subjects and I think definitely worth the time and effort.

When I posted this, I set the custom plate solving to plate solve for PGC, SDSS objects and quasars. In a field like this, I am always surprised by how much stuff is in a typical field. To that end, I did very little in the way of star reduction because you never know what you might be reducing and to me anyway, I like the idea of finding the tiny quasars and tiny galaxies more than I care about tiny stars.

Anyway, I hope you like this one, clear skies and good health to everyone!

Description: Re-processed from scratch. I never liked this image very much so I thought I would try to see if i could do a better job processing it.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
