NGC 253 with Sloan r band filter

NGC 253 with higher resolution (stellar FWHM ~2arcsec) than my previous attempt some years ago (>3arcsec). The complex dust detail appears better defined by the increased resolution as a result of changing from a Lum filter to a Sloan r band filter which has a longer wavelength cut-off on the short wavelength end of the bandpass (~400-700nm for Lum, vs ~550-700nm bandpass for the Sloan r band). At this object's low elevation angle for me (~30deg), my thought was to reduce the blue wavelength contribution and thus decrease the dispersion through the atmosphere. I also tripled the total integration time over three nights of observation to give better SNR. You will likely need to go to one of the higher resolution image versions to see the dust details.

All acquisition and processing in Maxim with gamma stretch and unsharp mask.

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.
