Caldwell 44 (aka NGC 7479)

All I had were problems shooting this target. Sadly I made a drastic error when I did not take the correct flats after the first imaging session, so I ended up with significant flat field correction errors when I tried using the second night flats. Also I got these weird color artifacts which is why I cropped the image quite significantly. I had to push the black point hard to hide the flat field errors. Ah well live and learn. This is Caldwell 44 / NGC7479. It is pretty small, 4.1′ × 3.1′ in size. It is a 105 million light-years away. I was itching to try a small galaxy without waiting for galaxy season. Last galaxy season I was using the AT130EDT and I felt that galaxies that are in the 20-40 million light years range were doable, anything farther was too small to tackle. So it is encouraging that now I can extend my reach to things that are now 100 million light years away and still get away with a decent picture.

I had to crop it significantly and push the background blackpoint just to get all the artifacts out unfortunately.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

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.
